Til tider kan din Enhedshåndtering^{(Device Manager)} på din Windows 11/10-computer rapportere en fejlkode. Hvis du ser en hardwarerelateret fejl, vil dette indlæg hjælpe dig med at identificere årsagen og vise dig, hvordan du løser problemet.

Hvis nogle af dine enheder ikke fungerer korrekt, kan det måske hjælpe dig at køre hardware- og enhedsfejlfinding ,  Windows USB-fejlfinding osv. Men hvis det ikke gør det, skal du muligvis finde ud af fejlkoden forbundet med dit problem og manuelt gå til specifik fejlfinding. I dette indlæg vil vi dele, hvordan du løser enhedshåndteringsfejl^{(Fix Device Manager Error)} .

Sådan finder du fejlkoder^{(Error Codes)} i Enhedshåndtering^{(Device Manager)}

For at finde ud af fejlkoden skal du åbne Enhedshåndtering^{(Device Manager)} , dobbeltklikke på den enhedstype, der har problemet. Højreklik derefter på den enhed, der har problemet, og klik derefter på Egenskaber^(Properties) . Dette åbner enhedens dialogboks Egenskaber . ^(Properties)Du kan se fejlkoden i området Enhedsstatus^(Device) i denne dialogboks.

Du skal muligvis opdatere eller installere enhedsdrivere , køre  hardware- og enhedsfejlfinding eller udføre systemgendannelse^{(perform System Restore)} som anbefalet i løsningerne.

Kode 1^{(Code 1)} : Denne enhed er ikke konfigureret korrekt

Hvis du modtager Device Manager- fejlkode  1 – Denne enhed er ikke konfigureret korrekt^{(Code 1 – This device is not configured correctly)} , betyder det, at den pågældende hardware ikke har nogen drivere installeret på computeren, eller at driveren ikke er konfigureret korrekt til, at enheden fungerer. For at løse problemet skal du fra Win + X Menu åbne Device Manager > Right-click på den hardware, der forårsager problemet, og vælg Egenskaber.

Klik^(Click) på Opdater driver^{(Update Driver)} . Dette vil internt kontrollere med Windows Update for at installere den seneste fungerende driver til den pågældende hardware. Hvis problemet fortsætter, enten fordi der ikke var nogen ny driver eller endda den seneste ikke virkede, skal du opdatere den manuelt.

Da opdatering af driveren ikke virkede, bliver du nødt til at downloade driveren fra OEM^(OEMs) 's websted manuelt. For at vide, hvilken version af driveren der er installeret, skal du gå til Egenskaber^(Properties) og kontrollere driverens version. Gå til OEM- webstedet og download enten en ældre version eller en ny version og installer den manuelt.

Kode 3^{(Code 3)} : Driveren til denne enhed kan være beskadiget

Hvis du modtager kode 3^{(Code 3)} for nogen af ​​dine enheder, betyder det, at du enten har et registreringsproblem eller et problem med lav hukommelse. Den fulde fejlmeddelelse siger -

Driveren til denne enhed kan være beskadiget, eller dit system er ved at løbe tør for hukommelse eller andre ressourcer. (Kode 3)^{(The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3))}

For at løse dette er der et par løsninger:

• Tjek hukommelse:^{(Check Memory: )} Åbn Jobliste^(Task) , og se, om du har ledig hukommelse. Hvis ikke, kan du lukke nogle applikationer, som bruger meget hukommelse. Du kan også tjekke systemressourcer^(System) og indstillinger for virtuel hukommelse og prøve at øge den.
  Hvis dette heller ikke hjælper, så bør du tænke på at øge RAM'en^(RAM) . Dette vil hjælpe dig med at starte og bruge flere applikationer.
• Afinstaller og geninstaller driveren:  ^{(Uninstall and reinstall the driver:  )} Nogle gange bliver enhedsdriveren ødelagt, eller endda poster i registreringsdatabasen er forkerte. Du kan prøve at afinstallere og derefter geninstallere drivere. Hvis det ikke hjælper, kan du prøve systemgendannelsen for at gå tilbage til et punkt, hvor driveren virkede.

Kode 9^{(Code 9)} : Windows kan ikke identificere denne hardware

Hvis du ser fejlkode 9^{(Code 9)} , kan Windows ikke identificere denne hardware; så er der et problem med den pågældende hardware eller enhed. Den fulde fejlmeddelelse vil sige

Windows kan ikke identificere denne hardware, fordi den ikke har et gyldigt hardware-identifikationsnummer. Kontakt hardwareproducenten for at få hjælp.^{(Windows cannot identify this hardware because it does not have a valid hardware identification number. For assistance, contact the hardware manufacturer.)}

Ugyldigt enheds-id^{(Invalid Device ID)} betyder, at operativsystemet ikke kan genkende hardwaren. Selvom du måske forsøger at opdatere driveren til den hardware, vil det ikke virke.  Windows installerer kun drivere til de enheder, det genkender. Så den bedste løsning er at kontakte hardwareleverandøren og få den udskiftet så hurtigt som muligt.

Kode 10^{(Code 10)} : Denne enhed kan ikke starte. Prøv at opgradere enhedsdriverne til denne enhed.

Fejlmeddelelsen genereres, når Enhedshåndteringen^{(Device Manager)} ikke kan starte hardwareenheden på grund af forældede eller beskadigede drivere eller midlertidig hardwarefejl.

Denne enhed kan ikke starte. Prøv at opgradere enhedsdriverne til denne enhed. (Kode 10)^{(This device cannot start. Try upgrading the device drivers for this device. (Code 10))}

Så hvis en simpel genstart ikke løser problemet, skal du muligvis   afinstallere/opdatere enhedsdrivere og køre hardwarefejlfinding^{(Hardware Troubleshooter)} eller USB-fejlfinding .

Ifølge Microsoft formodes OEM'er^(OEMs) at  vise den nøjagtige årsag ved hjælp af FailReasonString- nøglen. Men hvis hardwarenøglen ikke indeholder en "FailReasonString"-værdi, vises meddelelsen ovenfor.

Kode 14^{(Code 14)} : Denne enhed kan ikke fungere korrekt, før du genstarter din computer. For at genstarte din computer nu skal du klikke på Genstart computer^{(Restart Computer)} .

Når du modtager en  Device Manager- fejlkode  14^{(Code 14)} , betyder det, at denne enhed ikke kan fungere korrekt, før du genstarter din computer. Fejlmeddelelsen udvides til:

Denne enhed kan ikke fungere korrekt, før du genstarter din computer. For at genstarte din computer nu skal du klikke på Genstart computer. ^{(This device cannot work properly until you restart your computer. To restart your computer now, click Restart Computer. )}

For at løse dette skal du blot genstarte din computer. Du kan enten genstarte ved at gå til Start > Shutdown > og vælge genstart eller bruge Alt + CTRL + Del til at genstarte din Windows 10 -pc. Hvis du sidder fast på en af ​​dem, skal du bare trykke på tænd/sluk-knappen i et stykke tid, indtil din pc lukker ned. Tryk derefter på tænd/sluk-knappen igen for at genstarte din pc.

Kode 18^{(Code 18)} : Geninstaller driverne til denne enhed.

Nogle gange vil en enhed fejle eller holde op med at fungere. Når du tjekker deres fortegnelse i Enhedshåndtering^{(Device Manager)} , vil den vise fejlen-

Geninstaller driverne til denne enhed (kode 18).^{(Reinstall the drivers for this device (Code 18).)}

Du kan enten geninstallere driveren ved manuelt at søge efter opdateringen eller fjerne driveren først og derefter vælge at installere den igen.

• Åbn Enhedshåndtering^{(Device Manager)} , og vælg den pågældende enhed. Højreklik på den, og vælg Opdater driver^{(Update Driver)} . Dette vil starte Windows Update -tjenesten og lede efter en opdatering. Hvis det er tilgængeligt, vil det installere det.
• Den anden metode er, hvor du vælger at afinstallere. Højreklik^{(Right-click)} på enhedsadministratorens enhed og vælg afinstaller, når installationen er færdig, vælg scan for hardwareændringer fra det øverste punkt.

Dette vil finde den enhed igen, og denne gang vælger at installere driveren manuelt. Du kan prøve at downloade driveren fra OEM -webstedet, og når du bliver bedt om at angive driverens sti, browser og vælge den driver du downloadede.

Kode 19^{(Code 19)} : Windows kan ikke starte denne hardwareenhed

Hvis du ser en kode 19- ^{(Code 19)} fejlmeddelelse^(Error) for en enhed i enhedshåndteringen, betyder det, at enhedens konfiguration er ufuldstændig eller beskadiget i registreringsdatabasen. Den fulde fejlmeddelelse ville sige -

Windows kan ikke starte denne hardwareenhed, fordi dens konfigurationsoplysninger (i registreringsdatabasen) er ufuldstændige eller beskadigede. (Kode 19)^{(Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19))}

Den primære^(Primary) årsag til, at dette sker, er, når mere end én service er indstillet til et drev, og der er en fejl ved at åbne servicenøglen eller hente servicenøglen fra driveren. Når jeg siger servicenøgle^{(Service Key)} , betyder det, at chaufføren har en nøgle til formularen-

HKLM\SYSTEM\CurrentControlSet\Services\DriverName

Hvis dette forsvinder eller ikke er defineret korrekt, vises denne fejlmeddelelse.

Der er to måder at rette det på. Den første er at afinstallere og geninstallere en driver . Den anden metode er at gendanne din Windows 10-computer  til et punkt, hvor denne enhed fungerede korrekt.

Kode 21^{(Code 21)} : Windows fjerner denne enhed

Denne  fejlkode 21^{(Error Code 21)} dukker op, når Windows er i gang med at fjerne en enhed, men processen er endnu ikke fuldført; denne fejlkode er normalt midlertidig og forsvinder med tiden, men hvis det lykkedes dig at få dine skarpe øjne på dette, så genstart din Windows 10 -pc et par gange for at fjerne dette.

Når det er sagt, hvis det stadig ikke løser det for dig, kan du:

• Prøv at udføre en ren opstart af Windows 10 -pc'en, og genstart derefter med normal tilstand.
• Kør Hardware^{(Run Hardware)} and Devices Troubleshooter , og det skulle hjælpe dig med at slippe af med disse meddelelser.

Denne fejl er noget, du bør være mindst bekymret over.

Kode 22: Denne enhed er deaktiveret

Hvis du modtager denne fejl i beskrivelsen af ​​enheden, der er angivet under enhedshåndteringen, betyder det blot, at enheden er blevet deaktiveret.

Denne enhed er deaktiveret (kode 22)^{(This device is disabled (Code 22))}

En enhed kan deaktiveres af mange årsager. Det kan skyldes, at Windows gjorde det, da det stødte på et alvorligt problem eller blev deaktiveret af brugeren i Enhedshåndtering^{(Device Manager)} .

For at løse dette problem skal du finde enheden deaktiveret i enhedshåndteringen, højreklikke på den og vælge indstillingen "Aktiver enhed." Om et øjeblik vil dette starte guiden Aktiver enhed^{(Enable Device Wizard)} . Følg instruktionerne, og enheden vil være online igen.

Kode 28^{(Code 28)} : Driverne til denne enhed er ikke installeret

Hvis du modtager en fejl for en af ​​enhederne på din computer, betyder det blot, at du skal installere drivere manuelt. Der er en række årsager til, at en driver muligvis ikke er installeret til en enhed.

Driverne til denne enhed er ikke installeret (kode 28)^{(The drivers for this device are not installed (Code 28))}

Inden du installerer det, kan det være en god idé at downloade driveren manuelt fra OEM eller hardwareleverandørens websted. Når overførslen er fuldført, skal du følge denne:

• Åbn Enhedshåndtering^{(Device Manager)} ( WIN + X + M , og find den pågældende enhed.
• Højreklik^{(Right-click)} på enheden, og slet den fra systemet.
• Gå nu tilbage til toppen af ​​enhedshåndteringen, og højreklik for at starte Scan for hardwareændringer for at geninstallere driveren.
• Computeren vil bede dig om at angive stien til driveren. Naviger^(Navigate) til den OEM -fil, du downloadede.

Bemærk: Nogle gange er udførelse af EXE -filen alt, hvad du behøver for at installere hardwaredriveren.

Kode 29:^{(Code 29:)} Denne enhed er deaktiveret, fordi enhedens firmware ikke gav den de nødvendige ressourcer.

Ofte bliver en enhed deaktiveret med Device Manager Error Code 29 , fordi enhedens firmware ikke gav den de nødvendige ressourcer. Dette er et hardwareproblem på lavt niveau, der kræver adgang til BIOS .

For at løse dette problem skal du først notere enhedsnavnet og derefter genstarte din computer. Tryk på DEL- tasten eller F12 . Dette fører dig til BIOS. Søg nu efter enhedslisten, og denne enhed er i en deaktiveret tilstand. Hvis ja, aktiver det.

Hvis det stadig ikke virker, skal du muligvis tjekke fabrikantens^{(Manufacturers)} oplysninger om enheden for at se, om der er givet specielle instruktioner til at konfigurere den i BIOS .

Kode 31^{(Code 31)} : Denne enhed fungerer ikke korrekt

Hvis din enhed, der er angivet i Enhedshåndtering^{(Device Manager)} , viser en fejlkode 31^{(Error Code 31)} , betyder det blot, at enheden ikke fungerer korrekt, fordi Windows ikke kan indlæse de nødvendige drivere til denne enhed. Selvom du muligvis genstarter din computer flere gange for at se, om fejlen bliver løst, bliver du nødt til at geninstallere driverne igen, hvis den ikke gør det.

• Åbn Enhedshåndtering^{(Device Manager)} , og højreklik derefter på den enhed, der har dette problem.
• I menuen, der vises, skal du vælge Opdater driver^{(Update Driver)} for at starte guiden Hardwareopdatering .^{(Hardware Update)}
• Selvom Windows Update burde finde en stabil driver til dig, skal du downloade nye drivere fra OEM - webstedet og opdatere den manuelt, hvis den ikke kan.

Kode 33^{(Code 33)} : Windows kan ikke bestemme, hvilke ressourcer der kræves til denne enhed.

Hvis du modtager Windows ikke kan afgøre, hvilke ressourcer der kræves for denne enhed ( kode 33^{(Code 33)} ) fejl for en enhed, betyder det, at BIOS - oversætteren, der bestemmer, hvilken type ressourcer enheden kræver, har fejlet. Beskeden vil også sige:

Windows kan ikke bestemme, hvilke ressourcer der kræves til denne enhed.^{(Windows cannot determine which resources are required for this device.)}

Den eneste udvej er at bruge Setup Utility til at nulstille alt eller opdatere BIOS^{(Update the BIOS)} . Du skal downloade den seneste BIOS -fil fra hardwareleverandøren og derefter opdatere den. Udover dette kan du også prøve at konfigurere^(Configure) , reparere eller udskifte hardware.

Hvis disse ikke hjælper, skal du muligvis købe ny hardware.

Kode 34^{(Code 34)} : Windows kan ikke bestemme indstillingerne for denne enhed

Mange enheder på Windows bruger ressourcer til at udføre det, de skal gøre. Mens Windows automatisk kan bestemme ressourcen for hver af disse enheder, får du en fejlkode 34^{(Error Code 34)} , hvis den fejler . Fuld fejlmeddelelse^{(Full Error Message)} inkluderer-

Windows kan ikke bestemme indstillingerne for denne enhed. Se dokumentationen, der fulgte med denne enhed, og brug fanen Ressource til at indstille konfigurationen. (Kode 34)^{(Windows cannot determine the settings for this device. Consult the documentation that came with this device and use the Resource tab to set the configuration. (Code 34))}

Bemærk: En ressource er binære data, som du kan tilføje til en Windows-baseret applikations eksekverbare fil. Det kan være i form af IO, Memory eller noget andet.

Mens Windows kan finde ud af og bruger automatiske indstillinger, er det muligt at konfigurere det manuelt, hvis det ikke virker. Du skal dog bruge en manuel konfiguration af enheden. Du kan enten finde eller bede OEM 's supportteam om at hjælpe dig med hardwaredokumentationen for instruktioner om manuel konfiguration af enheden.

Når du har konfigureret, skal du genstarte din computer og derefter kontrollere, om den fungerer fint. For manuelt at ændre ressourceværdierne skal du skifte til enhedens ressourcefane^(Resource) i Enhedshåndtering^{(Device Manager)} . Skift fra automatisk til manuel, og følg dokumentationen.

Kode 35^{(Code 35)} : Din computers systemfirmware indeholder ikke nok information

Beskeden er:

Din computers systemfirmware indeholder ikke nok information (kode 35)^{(Your computer’s system firmware does not include enough information (Code 35))}

Det vises på en af ​​enhederne; det betyder, at din computers firmware ikke har tilstrækkelig support eller drivere til at konfigurere og bruge den korrekt. Kort sagt, BIOS er forældet og skal opdateres.

Når det sker, mangler MPS eller Multiprocessor System- tabellen, der gemmer BIOS - ressourcetildelingerne, en post for din enhed og skal opdateres.

Jeg anbefaler dig at downloade den seneste BIOS -opdatering fra din computers OEM - websted. Du bliver nødt til omhyggeligt at finde ud af den rigtige BIOS -opdatering til din computer, hvilket afhænger af bundkortets version.

Kode 36^{(Code 36)} : Denne enhed anmoder om en PCI - afbrydelse

Denne enhed anmoder om en PCI - afbrydelse ( kode 36^{(Code 36)} ) for at blive vist på enhedsstatus, når den anmoder om en PCI - afbrydelse, men er konfigureret til en ISA - afbrydelse og omvendt. Dette er lidt af en teknisk fejlkode, hvor du skal bruge en administrator eller en person, der forstår dette problem og træffe passende foranstaltninger.

Fuld fejlmeddelelse går som—

Denne enhed anmoder om en PCI-afbrydelse, men er konfigureret til en ISA-afbrydelse (eller omvendt). Brug venligst computerens systemopsætningsprogram til at genkonfigurere afbrydelsen for denne enhed.^{(This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer’s system setup program to reconfigure the interrupt for this device.)}

For at løse dette skal du ændre indstillingerne for IRQ reservationer i BIOS . Da BIOS varierer for hver OEM , er det bedst at se hardwaredokumentationen eller kontakte din computers producent.

Hvis din BIOS leveres med et opsætningsværktøj, kan du ændre indstillingerne for IRQ - reservationer. I sjældne tilfælde kan BIOS'en^(BIOS) have muligheder for at reservere visse IRQ'er^(IRQs) til PCI- eller ISA -enheder.

Kode 39^{(Code 39)} : Windows kan ikke indlæse enhedsdriveren til denne hardware

Når Windows bruger en enhed, indlæser den sin driver i hukommelsen og kommunikerer derefter med enheden. Dette er ligesom uden en driver; du kan ikke køre bil. Hvis du modtager en fejlkode 39 for en enhed, betyder det, at Windows ikke er i stand til at indlæse enhedsdriveren. De fulde fejlmeddelelser siger

Windows kan ikke indlæse enhedsdriveren til denne hardware. Driveren kan være beskadiget eller mangler. (Kode 39)^{(Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39))}

Den eneste anbefalede løsning til dette er at geninstallere driveren til den pågældende enhed. Du kan også prøve at fjerne enheden helt og derefter udføre scanningen for en hardwareændring og derefter installere driveren. Nogle gange er der de nyeste drivere tilgængelige med OEM'er^(OEMs) , og det giver mere mening at bruge den nyeste driver til den enhed.

Kode 40^{(Code 40)} : Windows kan ikke få adgang til denne hardware

Hvis du får Windows kan ikke få adgang til denne hardware ( kode 40^{(Code 40)} ) fejl på en af ​​dine enheder, betyder det, at Windows ikke kan få adgang til den hardware. Denne fejl vises kun, når enhedens servicenøgle eller undernøgleoplysninger i registreringsdatabasen mangler eller er registreret forkert. Den eneste måde at løse dette problem på er at geninstallere enhedsdriveren manuelt.

• Åbn enhedshåndteringen, og vælg den pågældende enhed.
• Højreklik^{(Right-click)} på enheden, og vælg Afinstaller^(Uninstall) i menuen, der vises.
• Vælg derefter Handling^(Action) på menulinjen, og vælg Scan for hardwareændringer for at geninstallere driveren.

Når enheden er fundet, vil Windows Update Service finde og installere nye drivere. Men hvis du har downloadet en stabil version fra OEM- hjemmesiden, kan du vælge at installere den manuelt.

Kode 41^{(Code 41)} : Windows indlæste enhedsdriveren, men kan ikke finde hardwaren

Det vises for de enheder, der har tilsluttet en ikke-plug and play-enhed og har installeret driveren. Mens enhedsdriveren til hardwaren indlæses uden fejl, kan Windows OS ikke finde hardwareenheden.

Den eneste løsning er at fjerne og finde enheden manuelt. Følg trinene for at geninstallere det:

• Åbn Enhedshåndtering^{(Device Manager)} ved hjælp af genvejstasten Win + X + M
• Højreklik^{(Right-click)} på den enhed, som du har kode 41- fejl^(Error) for .
• Vælg Afinstaller^{(Select Uninstall)} i menuen, der vises.
• Når det er fjernet, skal du klikke på computerikonet og højreklikke.
• Vælg nu Scan for hardwareændringer for at geninstallere driveren.

Når den finder enheden, vil den bede dig om også at installere driveren. Du kan enten installere driveren, downloade manuelt fra OEM - webstedet eller lade Windows søge^{(Windows Search)} efter det. Post denne fejl skal være løst.

Kode 42^{(Code 42)} : En dublet enhed, der allerede kører i systemet

Nogle gange bliver Windows forvirret på grund af en identisk underproces, hvilket resulterer i fejlkode 42^{(Error Code 42)} . Når du kontrollerer enhedens status i Enhedshåndtering^{(Device Manager)} , vil den sige-

Windows kan ikke indlæse enhedsdriveren til denne hardware, fordi der allerede er en dublet enhed, der kører i systemet. (Kode 42)^{(Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42))}

Fejlen kan også opstå, når en enhed med et serienummer opdages på en ny placering, før den fjernes fra den gamle placering.

Den eneste måde at løse dette på er at genstarte din Windows -pc, og det vil automatisk sætte tingene på plads igen.

Kode 44^{(Code 44)} : En applikation eller tjeneste har lukket denne hardwareenhed

Hardwareenheder^(Hardware) styres af operativsystemet, applikationen^{(Application)} og endda tjenester. Da de fuldstændigt kan interagere med enhederne, genstartes de for at sikre, at operationen er glat. Det kan dog ske, at enheden lukkes ned og aldrig genstartes. Det er her du får fejlen -

En applikation eller tjeneste har lukket denne hardwareenhed (kode 44).^{(An application or service has shut down this hardware device (Code 44).)}

Det er interessant at bemærke, at fejlkode^(Error) 44 kan vises når som helst. Det kan være under programinstallation eller under Windows-start^{(Windows Startup)} eller endda lukke ned. For at løse dette er alt, hvad du skal gøre, at genstarte din computer, og det skulle løse det.

Men hvis dette heller ikke løser problemet, kan det være et korrupt register. Du kan bruge en registry cleaner til at slippe af med alle beskadigede og ugyldige poster. Genstart derefter din computer for at se, om problemet er løst.

Kode 46^{(Code 46)} : Windows kan ikke få adgang til denne hardwareenhed

Nogle gange er enheden, selvom den er angivet i Enhedshåndtering^{(Device Manager)} , ikke tilgængelig for Windows . Hvis du får denne fejlmeddelelse som en pop-up, betyder det normalt, at en eller anden proces forsøgte at få adgang til den, men mislykkedes, fordi systemet lukker ned.

Windows kan ikke få adgang til denne hardwareenhed, fordi operativsystemet er ved at lukke ned. Hardwareenheden skulle fungere korrekt, næste gang du starter din computer. (Kode 46)^{(Windows cannot gain access to this hardware device because the operating system is in the process of shutting down. The hardware device should work correctly next time you start your computer. (Code 46))}

Den gode nyhed er, at du ikke behøver at løse dette problem, men når du genstarter systemet, vil applikationen eller processen få adgang til det igen og få arbejdet gjort.

Bemærk: Denne fejlkode er kun indstillet, når  Driver Verifier er aktiveret , og alle programmer allerede er blevet lukket ned.

Kode 47^{(Code 47)} : Windows kan ikke bruge denne hardwareenhed

Den mest fremtrædende ting, du vil huske ved at bruge en USB -enhed, er Safe Eject . Når du gør det, hvis du kommer til at se fejlkode 47^{(Error Code 47)} for en sådan enhed, betyder det, at den er ved at blive udstødt. Den fulde fejlmeddelelse for et sådant scenarie er:

Windows kan ikke bruge denne hardwareenhed, fordi den er forberedt til sikker fjernelse, men den er ikke blevet fjernet fra computeren. For at løse dette problem skal du koble denne enhed fra din computer og derefter tilslutte den igen. (Kode 47)^{(Windows cannot use this hardware device because it has been prepared for safe removal, but it has not been removed from the computer. To fix this problem, unplug this device from your computer and then plug it in again. (Code 47))}

Selvom processen næppe tager nogen tid, men i tilfælde af at den sætter sig fast, og Windows stadig forbereder enheden til fjernelse eller trykker på en fysisk udløserknap, så følg nedenstående metode.

Du kan enten tage stikket ud og tilslutte det igen (sørg for, at der ikke er nogen filkopiering eller flytning i processen), eller du kan genstarte din computer for at nulstille denne status.

Kode 48^{(Code 48)} : Softwaren til denne enhed er blevet blokeret

Denne fejlkode 48 dukker normalt op, når du opgraderer fra en funktionsopdatering til en anden. Hvis en enhed med en enhed under intern test rapporteres at skabe et problem, og OEM'en^(OEM) ikke tilbød en opdatering, vil du se denne meddelelse.

Softwaren til denne enhed er blevet blokeret fra at starte, fordi den er kendt for at have problemer med Windows. Kontakt hardwareleverandøren for at få en ny driver. (Kode 48)^{(The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48))}

Den eneste rigtige løsning er at installere en kompatibel driver, der fungerer med den aktuelle version af Windows . Du bliver nødt til at tjekke med OEM for at vide, om der er en ny opdatering. Hvis ikke, kan du prøve at installere den eneste driver med kompatibilitetstilstand for at se, om problemet løser sig for dig.

Kode 50^{(Code 50)} : Windows kan ikke anvende alle egenskaberne for denne enhed

Hver enhed kommer med flere funktioner. Driverne sørger for, at Windows kan identificere hver af disse egenskaber for at gøre brug af dens funktionalitet. Men hvis du får fejlkode 50^{(Error Code 50)} for nogen af ​​enhederne, betyder det, at Windows ikke kan anvende alle egenskaberne for den pågældende enhed. Den fulde fejlmeddelelse^(Error) inkluderer

Windows kan ikke anvende alle egenskaberne for denne enhed. Enhedsegenskaber kan omfatte oplysninger, der beskriver enhedens muligheder og indstillinger (såsom sikkerhedsindstillinger, for eksempel). For at løse dette problem kan du prøve at geninstallere denne enhed. Vi anbefaler dog, at du kontakter hardwareproducenten for at få en ny driver. (Kode50)^{(Windows cannot apply all of the properties for this device. Device properties may include information that describes the device’s capabilities and settings (such as security settings, for example). To fix this problem, you can try reinstalling this device. However,we recommend that you contact the hardware manufacturer for a new driver. (Code50))}

Den eneste måde at løse dette problem på er at geninstallere enheden og derefter genindlæse driverne igen. Hvis det er muligt, skal du finde den nyeste version af driveren fra OEM^(OEMs) 's websted og installere den manuelt.

• Højreklik^{(Right-click)} på enheden på listen, og vælg at afinstallere.
• Scan derefter for nye hardwareændringer i enhedshåndteringen.
• Når den finder ud af ny hardware, har du mulighed for at geninstallere driveren manuelt.
• Når den er installeret, genstart din computer til Windows kan anvende alle indstillingerne.

Kode 51^{(Code 51)} : Denne enhed venter i øjeblikket på en anden enhed

Det er muligt, at enheder skal vente på, at hinanden enten udfører noget arbejde eller bare skal være i rækkefølge. Hvis du får fejlkode 51, betyder det, at enheden i øjeblikket venter på en anden enhed eller et sæt af enheder for at starte. Sagen ved situationen er, at der ikke er nogen løsning, og du er nødt til at lade være, som den er. Medmindre enheden fejler, har du virkelig ingen løsning. Hvis problemet fortsætter meget længere, kan det være en god idé at genstarte din Windows 10-computer.

Du kan også kontrollere, om andre enheder fejlede i Enhedshåndtering^{(Device Manager)} , på grund af denne enhed er gået i intern ventetid. Genstart din computer, eller ret en anden enhed for at løse dette. Sørg også for at køre hardwarefejlfinding .

Kode 52^{(Code 52)} : Windows kan ikke bekræfte den digitale signatur for driverne

Hvis du får en fejlmeddelelse, der siger: " Windows kan ikke bekræfte den digitale signatur for de drivere, der kræves til denne enhed. ( Kode 52^{(Code 52)} ), så betyder det, at chaufføren kan være usigneret eller beskadiget. Den fulde fejlmeddelelse lyder som-

Windows kan ikke bekræfte den digitale signatur for de drivere, der kræves til denne enhed. En nylig hardware- eller softwareændring kan have installeret en fil, der er signeret forkert eller beskadiget, eller som kan være skadelig software fra en ukendt kilde. (Kode 52)^{(Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52))}

Du har muligvis downloadet en usigneret driver fra et sted og prøvet at installere den. Hvis det ikke er tilfældet, er driverfilerne blevet beskadiget på grund af en eller anden grund. I begge tilfælde skal du geninstallere driveren igen. Sørg for at downloade det fra enhedsleverandørens^(Device) websted.

Kode 53^{(Code 53)} : Denne enhed er reserveret til brug af Windows -kernefejlfinderen

Kernel Debugging hjælper en med at finde ud af problemer i detaljer, så hvis du ser kode 53^{(Code 53)} på en enhed, der er angivet under Enhedshåndtering^{(Device Manager)} , betyder det, at den er reserveret til brug af Windows -kernedebuggeren i varigheden af ​​denne opstartssession. ( Kode 53^{(Code 53)} ). Dette sker for det meste, når en it-administrator eller en person, der har tilstrækkelig viden om Windows 10 Kernel Debugging , forsøger at fejlfinde problemer omkring enheden.

For at løse dette problem skal du have administratorrettigheder og adgang til kreditkommandoen. Skriv og udfør i kommandoprompten bcdedit /debug off. Når du har deaktiveret Windows -kernefejlfinding, vil det tillade enheden at starte normalt.

Kode 54^{(Code 54)} – Denne enhed har fejlet og gennemgår en nulstilling

Nogle gange skal Windows eller selve enheden genstarte. Selvom det normalt er hurtigt, men hvis det lykkedes dig at fange en enhed i en sådan tilstand, giver det fejlkode 54^{(Code 54)} . Dette er en intermitterende problemkode, der tildeles, mens en ACPI - nulstillingsmetode udføres. Selvom det automatisk løser sig selv om et stykke tid, hvis enheden aldrig genstarter på grund af en fejl, vil den sidde fast i denne tilstand, og systemet skal genstartes. Så genstart blot din Windows 10 -pc og tjek enhedens status igen i Enhedshåndtering^{(Device Manager)} . Det burde være væk for altid.

Jeg håber, at dette indlæg hjælper dig.

You may have to update or install device drivers,  run the Hardware and Devices Troubleshooter, or perform System Restore as recommended in the solutions.

Code 1: This device is not configured correctly

If you receive Device Manager error Code 1 – This device is not configured correctly, it means that the particular hardware in question has no drivers installed on the computer or the driver is not configured properly for the device to work. To resolve the issue, from the Win + X Menu, open Device Manager > Right-click on the hardware causing the issue, and select Properties.

Click on Update Driver. This will internally check with the Windows Update to install the latest working driver for that hardware. If the problem persists, either because there was no new driver or even the latest one did not work, you will need to update it manually.

Since updating the driver did not work, you will have to download the driver from the OEMs website manually. To know which version of the driver is installed, go to Properties and check the driver’s version. Go to the OEM website and either download an older version or a new version and install it manually.

Code 3: The driver for this device might be corrupted

If you are receiving Code 3 for any of your devices, it means you either have a registry issue or low memory issue. The full error message says –

The driver for this device might be corrupted, or your system may be running low on memory or other resources. (Code 3)

To resolve this, there are a few solutions:

• Check Memory: Open Task manager, and see if you have free memory. If not, then you can close some applications which are consuming a lot of memory. You can also check on System resources and virtual memory settings and try increasing it.
  If this also doesn’t help, then you should think of increasing the RAM. This will help you launch and use more applications.
• Uninstall and reinstall the driver:  Sometimes, the device driver gets corrupted, or even registry entries are not right. You can try uninstalling and then reinstalling drivers. If that doesn’t help, you can try the system restore to go back to a point where that driver was working.

Code 9: Windows cannot identify this hardware

If you see Error Code 9, Windows cannot identify this hardware; then there is a problem with that particular hardware or device. The full error message will say

Windows cannot identify this hardware because it does not have a valid hardware identification number. For assistance, contact the hardware manufacturer.

Invalid Device ID means that the OS fails to recognize the hardware. While you may try to update the driver of that hardware, it will not work.  Windows Only installs drivers for the devices it recognizes.  So the best solution is to contact the hardware vendor and get it replaced as soon as possible.

Code 10: This device cannot start. Try upgrading the device drivers for this device.

The error message is generated when the Device Manager can’t start the hardware device due to outdated or corrupted drivers or temporary hardware failure.

This device cannot start. Try upgrading the device drivers for this device. (Code 10)

So if a simple restart doesn’t resolve the problem, then may have to  Uninstall/Update Device Drivers and run the Hardware Troubleshooter or USB Troubleshooter.

According to Microsoft,  OEMs are supposed to display the exact cause using the FailReasonString key. However, if the hardware key does not contain a “FailReasonString” value, the message above is displayed.

Code 14: This device cannot work properly until you restart your computer. To restart your computer now, click Restart Computer.

When you receive a Device Manager error Code 14, it means this device cannot work properly until you restart your computer. The error message expands to:

This device cannot work properly until you restart your computer. To restart your computer now, click Restart Computer. 

To resolve this, simply restart your computer. You can either restart by going to Start > Shutdown > and select restart or use Alt + CTRL + Del to restart your Windows 10 PC.  In case you are stuck on either of them, just press the power button for a while until your PC shuts down. Then press the power button again to restart your PC.

Code 18: Reinstall the drivers for this device.

Sometimes a device will fail or stop working. On checking with their listing on the Device Manager, it will display the error-

Reinstall the drivers for this device (Code 18).

You can either reinstall the driver by manually checking for the update or remove the driver first and then choose to install it again.

• Open Device Manager, and select the device in question. Right-click on it, and choose Update Driver. This will initiate Windows Update service, and look for an update. If available, it will install it.
• The second method is where you choose to uninstall. Right-click on the device manager’s device and select uninstall once the installation is complete, select scan for hardware changes from the top item.

This will find that device again, and this time chooses to install the driver manually. You can try to download the driver from the OEM website, and when prompted to provide the driver’s path, browser, and select the driver you downloaded.

Code 19: Windows cannot start this hardware device

If you see a Code 19 Error message for a device in the device manager, it means the device’s configuration is incomplete or corrupted in the registry hive. The full error message would say—

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

The Primary reason for this to happen is when more than one service is set for one drive, and there is a failure opening the service key or retrieving the service key from the driver. When I say Service Key, it means that driver has a key to the form-

HKLM\SYSTEM\CurrentControlSet\Services\DriverName

If this goes missing or is not defined properly, this error message shows up.

There are two ways to fix it. The first is to uninstall and reinstall a driver. The second method is to restore your Windows 10 computer to a point where this device was working properly.

Code 21: Windows is removing this device

This Error Code 21 shows up when Windows is in the process of removing a device, but the process is not yet complete; this error code is usually temporary and goes away with time, but if you managed to get your sharp eyes on this, then restart your Windows 10 PC a couple of times to remove this.

That said, if it still doesn’t resolve it for you can:

• Try performing a clean boot of Windows 10 PC, and then reboot back using normal mode.
• Run Hardware and Devices Troubleshooter, and it should help you get rid of those messages.

This error is something you should be least bothered about.

Code 22: This device is disabled

If you are receiving this error on the description of the device listed under the device manager, then it simply means that the device has been disabled.

This device is disabled (Code 22)

A device can be disabled for many reasons. It could be because Windows did it when it encountered some serious problem or was disabled by the user in Device Manager.

To resolve this issue, find the device disabled in the device manager, right-click on it, and select the option “Enable Device.” In a moment, this will start the Enable Device Wizard. Follow the instructions, and the device will be back online.

Code 28: The drivers for this device are not installed

If you are receiving an error for one of the devices on your computer, then it simply means you need to install drivers manually. There is any number of reasons that a driver might not be installed for a device.

The drivers for this device are not installed (Code 28)

Before installing it, you may want to manually download the driver from the OEM or the hardware vendor’s website. Once the download is complete, follow this:

• Open Device Manager (WIN + X + M, and find the device in question.
• Right-click on the device, and delete it from the system.
• Now go back to the top of the device manager, and right-click to initiate the Scan for hardware changes to reinstall the driver.
• The computer will prompt you to provide the path of the driver. Navigate to the OEM file you downloaded.

Note: Sometimes, executing the EXE file is all you need to install the hardware driver.

Code 29: This device is disabled because the firmware of the device did not give it the required resources.

Often, a device gets disabled with Device Manager Error Code 29 because the firmware of the device did not give it the required resources. This is a low-level hardware problem that will need access to the BIOS.

First, to resolve this issue, make a note of the device name, and then restart your computer. Press the DEL key or F12. This will take you to the BIOS. Now search for the devices list, and this device is in a disabled state. If yes, enable it.

In case it still doesn’t work, you may have to check the Manufacturers’s information about the device to see if there are special instructions given to configure it in the BIOS.

Code 31: This device is not working properly

If your device listed in Device Manager shows an Error Code 31, it simply means that the device is not working properly because Windows cannot load the drivers required for this device. While you may restart your computer multiple times to see if the error gets resolved, if it doesn’t, you will have to reinstall the drivers once again.

• Open Device Manager, and then right-click on the device which is having this issue.
• On the menu that appears, choose Update Driver to start the Hardware Update wizard.
• While Windows Update should find a stable driver for you, in case it cannot, download new drivers from the OEM website and manually update it.

Code 33:  Windows cannot determine which resources are required for this device.

If you receive Windows cannot determine which resources are required for this device (Code 33) error for any device, it means the BIOS translator that determines the kind of resources required by the device has failed. The message will also say:

Windows cannot determine which resources are required for this device.

The only way out is to use the Setup Utility to reset everything or Update the BIOS. You will have download the latest BIOS file from the hardware vendor and then update it. Apart from this, you can also try to Configure, repair, or replace hardware.

If these don’t help, you may have to buy new hardware.

Code 34: Windows cannot determine the settings for this device

Many devices on Windows use resources to execute what they are supposed to do. While Windows can automatically determine the resource for each of these devices, in case it fails, you get an Error Code 34. Full Error Message includes—

Windows cannot determine the settings for this device. Consult the documentation that came with this device and use the Resource tab to set the configuration. (Code 34)

Note: A resource is binary data that you can add to a Windows-based application’s executable file. It can be in the form of IO, Memory, or anything else.

While Windows can figure out and uses automatic settings, it is possible to configure it manually if it doesn’t work. However, you will need a device manual configuration. You can either find or ask the support team of OEM to help you with the hardware documentation for instructions on manually configuring the device.

Once you have configured, reboot your computer, and then check if it is working fine. To manually change the resource values, you need to switch to the device’s Resource tab in Device Manager. Switch from automatic to manual, and follow the documentation.

Code 35:  Your computer’s system firmware does not include enough information

The message is:

Your computer’s system firmware does not include enough information (Code 35)

It appears on one of the devices; it means that your computer’s firmware doesn’t have enough support or drivers to configure and use it properly. In short, the BIOS is outdated and needs to be updated.

When it happens, the MPS or the Multiprocessor System table that stores the BIOS resource assignments is missing an entry for your device and must be updated.

I recommend you to download the latest BIOS update from your computer’s OEM website. You will have to carefully figure out the right BIOS update for your computer, which depends on the motherboard version.

Code 36: This device is requesting a PCI interrupt

This device is requesting a PCI interrupt (Code 36) to appear on the device status when it is requesting a PCI interrupt but is configured for an ISA interrupt, and vice versa. This is a bit of a technical error code where you will need an admin or a person who understands this problem and take appropriate action.

Full error message goes as—

This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer’s system setup program to reconfigure the interrupt for this device.

To resolve this, you will have to change the settings for IRQ reservations in the BIOS. Since BIOS varies for every OEM, it is best to see the hardware documentation or contact your computer’s manufacturer.

In case your BIOS comes with a setup tool, you can change the settings for IRQ reservations. On rare occasions, the BIOS might have options to reserve certain IRQs for peripheral component interconnect (PCI) or ISA devices.

Code 39:  Windows cannot load the device driver for this hardware

When Windows uses a device, it loads its driver into memory and then communicates with the device. This is just like without a driver; you cannot run a car. If you are receiving an error code 39 for any device, this means Windows is not able to load the device driver. The full error messages say

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

The only recommended solution for this is to reinstall the driver for that device. You can also try removing the device completely, and then perform the scan for a hardware change, and then install the driver. Sometimes there are the latest drivers available with OEMs, and it makes more sense to use the latest driver for that device.

Code 40: Windows cannot access this hardware

If you are getting Windows cannot access this hardware (Code 40) error on one of your devices, it means that Windows cannot access that hardware. This Error shows up only when the device’s service key or subkey information in the registry is missing or recorded incorrectly. The only way to resolve this issue is to reinstall the device driver manually.

• Open the device manager, and select the device in question.
• Right-click on the device and select Uninstall from the menu that appears.
• Next, choose Action on the menu bar, and select Scan for hardware changes to reinstall the driver.

Once the device is detected, Windows Update Service will find and install new drivers. However, if you have downloaded a stable version from the OEM website, you can choose to install it manually.

Code 41: Windows successfully loaded the device driver but cannot find the hardware

It appears for the devices which have plugged-in a non-plug and play device and have installed the driver. While the device driver for the hardware is loaded without an error, the Windows OS cannot find the hardware device.

The only solution is to remove and find the device manually. Follow the steps to reinstall it:

• Open Device Manager using shortcut key Win + X + M
• Right-click on the device for which you have Code 41 Error.
• Select Uninstall from the menu that appears.
• Once it is removed, click on the computer icon and right-click.
• Now select Scan for hardware changes to reinstall the driver.

Once it finds the device, it will prompt you to install the driver as well. You can either install the driver, manually download from the OEM website, or let Windows Search for it. Post this error should be resolved.

Code 42: A duplicate device already running in the system

Sometimes Windows gets confused because of an identical subprocess, which results in Error Code 42. When you check on the status of the device in Device Manager, it will say-

Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system. (Code 42)

The error could also happen when a device with a serial number is discovered in a new location before it is removed from the old location.

The only way to resolve this is to restart your Windows PC, and it will automatically put things back into place.

Code 44: An application or service has shut down this hardware device

Hardware devices are controlled by the OS, Application, and even services. Since they can completely interact with the devices, they are rebooted to ensure the operation is smooth. However, it may so happen that the device is shut down and never rebooted. This is where you get the error –

An application or service has shut down this hardware device (Code 44).

It is interesting to note that Error code 44 can appear at any time. It could be during program installation, or during Windows Startup, or even shut down. To resolve this, all you need to do is restart your computer, and it should fix it.

However, if this also doesn’t solve the problem, it could be a corrupt registry. You can use a registry cleaner to get rid of all corrupted and invalid entries. Then reboot your computer to see if the issue was resolved.

Code 46:  Windows cannot gain access to this hardware device

Sometimes the device, even though listed in the Device Manager, is not accessible by the Windows.  In case you got this error message as a pop-up, it usually means that some process was trying to access it but failed because the system is shutting down.

Windows cannot gain access to this hardware device because the operating system is in the process of shutting down. The hardware device should work correctly next time you start your computer. (Code 46)

The good news is that you do not have to resolve this issue, but when you restart the system, the application or process will reaccess it and get its work done.

Note: This error code is only set when Driver Verifier is enabled, and all applications have already been shut down.

Code 47: Windows cannot use this hardware device

The most prominent thing you will remember about using a USB device is the Safe Eject. When doing so, if you get to see Error Code 47 for one such device, it means it’s in the process of ejection. The full error message for such a scenario is :

Windows cannot use this hardware device because it has been prepared for safe removal, but it has not been removed from the computer. To fix this problem, unplug this device from your computer and then plug it in again. (Code 47)

While the process hardly takes any time, but in case it gets stuck, and Windows is still preparing the device for removal or pressed a physical eject button, then follow the below method.

You can either unplug and plug it back in (make sure there is no file copy or move in the process), or you can restart your computer to do a reset for this status.

Code 48: The software for this device has been blocked

This error code 48 shows up usually when upgrading from one feature update to another. If, during internal testing, a device with a device is reported to be creating a problem, and the OEM did not offer an update, you will see this message.

The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)

The only correct solution is to install a compatible driver that works with the current version of Windows. You will need to check with the OEM to know if there is a new update. If not, then you may try installing the only driver with compatibility mode to see if the problem resolves for you.

Code 50: Windows cannot apply all of the properties for this device

Every device comes with multiple functions. The drivers make sure Windows can identify each of these properties to make use of its functionality. However, if you are getting Error Code 50 for any of the devices, it means that Windows cannot apply all the properties of that device.  The full Error message includes

Windows cannot apply all of the properties for this device. Device properties may include information that describes the device’s capabilities and settings (such as security settings, for example). To fix this problem, you can try reinstalling this device. However,we recommend that you contact the hardware manufacturer for a new driver. (Code50)

The only way to fix this problem is to reinstall the device and then reload the drivers again. If possible, figure out the latest version of the driver from the OEMs website and install it manually.

• Right-click on the device in the list, and choose to uninstall.
• Then scan for new hardware changes in the device manager.
• Once it figures out new hardware, you will have the option to reinstall the driver manually.
• Once installed, reboot your computer to Windows can apply all the settings.

Code 51: This device is currently waiting on another device

It is possible that devices need to wait for each other to either complete some work or just have to be in sequence. If you are getting error code 51, then it means that the device is currently waiting on another device or set of devices to start. The thing about the situation is that there is no resolution, and you need to leave as it is. Unless the device fails, you really have no solution. If the issue stays around much longer, then you may want to reboot your Windows 10 computer.

You can also check if other devices failed in the Device Manager because of which this device has gone into internal wait. Restart your computer or fix another device to resolve this. Also, make sure to run the Hardware Troubleshooter.

Code 52: Windows cannot verify the digital signature for the drivers

If you are getting an error message saying, “Windows cannot verify the digital signature for the drivers required for this device. (Code 52), then it means that driver may be unsigned or corrupted. The full error message goes like-

Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

You may have downloaded an unsigned driver from somewhere and tried installing it. If that’s not the case, then the driver files have been corrupted because of some reason. In either case, you will need to reinstall the driver again. Make sure you download it from the Device vendors website.

Code 53: This device has been reserved for use by the Windows kernel debugger

Kernel Debugging helps one to find out issues in detail, so if you see Code 53 on a device listed under Device Manager, it means that it has reserved for use by the Windows kernel debugger for the duration of this boot session. (Code 53). This mostly happens when an IT admin or someone who has enough knowledge about Windows 10 Kernel Debugging is trying to troubleshoot issues around the device.

To resolve this issue, you will need to have admin privileges and access to the credit command. In the command prompt, type and execute bcdedit /debug off. Once you disable the Windows kernel debugging, it will allow the device to start normally.

Code 54 – This device has failed and is undergoing a reset

Sometimes Windows or the device itself has to restart. While it’s usually fast, but if you managed to catch a device in such a state, it gives error Code 54. This is an intermittent problem code assigned while an ACPI reset method is being executed. While it will automatically resolve itself in a while, if the device never restarts due to a failure, it will be stuck in this state, and the system reboot is required. So simply restart your Windows 10 PC and recheck the device’s status in the Device Manager. It should be gone for good.

I hope this post helps you.
