Adobe Flash og Java er to downloads, de fleste af os har installeret på vores Windows -computere, da de giver os en rigere internet- og browsingoplevelse. Vi har allerede set, hvordan du administrerer Adobe Flash-indstillinger . I dag lærer vi om Java-indstillinger^{(Java Settings)} i Windows 10/8/7 .

Hvad er Java

Java er et programmeringssprog^{(Java is a programming language)} og computerplatform, som driver state-of-the-art programmer, herunder hjælpeprogrammer, spil og forretningsapplikationer. Det giver dig mulighed for at spille onlinespil, chatte med mennesker over hele verden, se billeder i 3D og meget mere.

Java kontrolpanel

Java -software eller Java Runtime Environment omtales også som Java Runtime , Runtime Environment , Runtime , JRE , Java Virtual Machine osv. Det kan styres fra Java-kontrolpanelet^{(Java Control Panel)} . For at få adgang til Java Kontrolpanel^{(Java Control Panel)} skal du åbne Kontrolpanel^{(Control Panel)} og klikke på Java . Her vil du kunne få oplysninger om versionsnummeret og også se^(View) filerne.

Fjern midlertidige Java-filer

Når du surfer på internettet, når din browser bruger Java , gemmes Java- filerne i særlige mapper for hurtigere udførelse senere.^(Java)

Klik på knappen Indstillinger^(Settings) for at se mappens placering og andre detaljer .

Som standard er disse midlertidige java-filer gemt i

C:\Users\Username\AppData\LocalLow\Sun\Java\Deployment\cache

mappe i JAR -format. Du kan indstille komprimeringsniveauet for disse JAR - filer og endda indstille det beløb, der skal afsættes til lagring af disse filer.

For at slette disse midlertidige Java JAR- filer skal du klikke på Slet filer^{(Delete Files)} . Nu kan du vælge hvilke filer du ønsker at slette og klikke på OK.

Ryd Java-cache ved hjælp af kommandolinjen

For at rydde Java -cache ved hjælp af kommandolinjen skal du åbne et kommandopromptvindue, skrive følgende og trykke på Enter:

javaws -uninstall

Java opdatering

Vi har en tendens til at ignorere at opdatere vores Java. ^{(We tend to ignore updating our Java.)} Men det er meget vigtigt, at vi altid sørger for, at du bruger den nyeste version af Java , da sårbarheder i Java ofte udnyttes til at kompromittere din computer. Den seneste Java- version indeholder vigtige forbedringer for at forbedre sikkerheden, ydeevnen og stabiliteten af ​​de Java -applikationer, der kører på din maskine. Når^(Whenever) der opdages sikkerhedshuller, bliver de rettet, og det er derfor bydende nødvendigt, at du sikrer dig, at du har den nyeste version af java installeret, da den indeholder sårbarhedsrettelser.

Du kan konfigurere Java- opdateringsindstillingerne ved at klikke på fanen Opdater^(Update) .

Sørg for, at Kontroller for opdateringer automatisk^{(Check for Updates Automatically)} er markeret. Ved at klikke på knappen Avanceret^(Advanced) kan du indstille hyppigheden af ​​opdateringskontrollen.

Jeg lagde i øvrigt mærke til, at det var længe siden, jeg havde opdateret Java . Så jeg klikkede på Opdater nu^{(Update Now)} for at starte opdateringsprocessen. Dette starter juscheck.exe- processen, som kontrollerer, om en opdatering er tilgængelig, og informerer dig derfor.

Ved at klikke på Installer^(Install) starter opdateringsprocessen. Når det er afsluttet, skal du klikke på Luk^(Close) .

Andre Java-indstillinger

Java- fanen giver dig mulighed for at se og administrere Java Runtime- versionerne og -indstillingerne for Java- applikationer og -applets.

Fanen Sikkerhed^(Security) giver dig mulighed for at se typen af ​​certifikater for at identificere dig selv.

Fanen Avanceret^(Advanced) giver dig mulighed for at konfigurere andre indstillinger.

Afinstaller gamle Java-versioner

At beholde gamle og ikke-understøttede versioner af Java på dit system udgør en alvorlig sikkerhedsrisiko.

Older versions of SunJava (up to JRE 6 update 7) indeed did remain when updates were installed and need to be removed as the older versions of SunJava are highly vulnerable to Winfixer/Vundo. It took from 2005 until the update late last year to JRE 6 update 10 for SunMicrosystems to Sun Microsystems to get the autoupdater of SunJava to uninstall previous (vulnerable) versions of the program. Updates from JRE 6 Update 10 forward are in a self-contained “jre6” folder that is overwritten if a new JRE is installed. Even when using the most up-to-date version of SunJava, if older, vulnerable, version(s) are still on your computer, it is vulnerable to infection. Unfortunately, simply using Add/Remove programs to uninstall the old versions is not completely affective.

Vi foreslår, at du prøver JavaRa . Efter at have opdateret Java til den seneste version i dag, kørte jeg JavaRa og brugte den til at fjerne ældre Java - versioner.

Den registrerede to ældre versioner på min computer, som jeg derefter fjernede.

BEMÆRK. ^(NOTE.)Min MVP - kollega og TWCF Mod Corrine tilføjer: JavaRa er ikke blevet opdateret til at understøtte fjernelse af JRE 7 og ser ud til at have problemer forbi JRE 6u32 . Den er flyttet til SingularLabs.com . Derudover understøtter Paul McLain ikke længere JavaRa , men det gør Freð ðe Vries^{(Freð ðe Vries)} stadig.

Java download

Du kan downloade og installere Java til Windows manuelt fra Java.com her^(here) .

Manage Java Settings in Windows 11/10

Adobe Flaѕh and Jаva are two downloads most of us have installed on our Windows computers, as thеy give us a richer internet and browsing expеrience. We haνe аlready seen how to managе Adobe Flash Settіngs. Todaу we will learn aboυt Java Settings in Windows 10/8/7.

What is Java

Java is a programming language and computing platform, which powers state-of-the-art programs including utilities, games, and business applications. It allows you to play online games, chat with people around the world, view images in 3D, and more.

Java Control Panel

Java software or the Java Runtime Environment is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, etc. It can be managed from the Java Control Panel. To access the Java Control Panel, open Control Panel and click on Java. Here you will be able to get information on the version number and also View the files.

Remove temporary Java files

When browsing the internet, whenever your browser uses Java, the Java files are stored in special folders for quicker execution later on.

To see the location of the folder and other details, click on the Settings button.

By default, these temporary java files are stored in the

C:\Users\Username\AppData\LocalLow\Sun\Java\Deployment\cache

folder in the JAR format. You can set the compression level for these JAR files and even set the amount to be set aside for storing these files.

To delete these temporary Java JAR files, click on Delete Files. Now you can select which files you wish to delete and click on OK.

Clear Java cache using command line

To clear Java cache using the command line, open a command prompt windows, type the following and press Enter:

javaws -uninstall

Java Update

We tend to ignore updating our Java. But it is very important that we always make sure that you are using the latest version of Java since vulnerabilities in Java are often exploited to compromise your computer. The latest Java version contains important enhancements to improve the security, performance, and stability of the Java applications that run on your machine. Whenever security holes are detected, they are patched, and it is therefore imperative that you ensure that you have the latest version of java installed as it includes vulnerability fixes.

You can configure the Java update settings by clicking on the Update tab.

Make sure that the Check for Updates Automatically is checked.  Clicking on the Advanced button will let you set the frequency of the update checks.

By the way, I noticed that it was a long time since I had updated Java. So I clicked on Update Now to start the update process. This starts the juscheck.exe process, which will check if an update is available and accordingly inform you.

Clicking on Install will start the update process. Once it is completed, click on Close.

Other Java settings

The Java tab lets you view and manage the Java Runtime versions and settings for Java applications and applets.

The Security tab lets you view the type of certificates to identify yourself.

The Advanced tab lets you configure other settings.

Uninstall Old Java versions

Keeping old and unsupported versions of Java on your system presents a serious security risk.

Older versions of SunJava (up to JRE 6 update 7) indeed did remain when updates were installed and need to be removed as the older versions of SunJava are highly vulnerable to Winfixer/Vundo. It took from 2005 until the update late last year to JRE 6 update 10 for SunMicrosystems to Sun Microsystems to get the autoupdater of SunJava to uninstall previous (vulnerable) versions of the program. Updates from JRE 6 Update 10 forward are in a self-contained “jre6” folder that is overwritten if a new JRE is installed. Even when using the most up-to-date version of SunJava, if older, vulnerable, version(s) are still on your computer, it is vulnerable to infection. Unfortunately, simply using Add/Remove programs to uninstall the old versions is not completely affective.

We suggest you try JavaRa. After updating Java to its latest version today, I ran JavaRa and used it to remove older Java versions.

It detected two older versions on my computer, which I then removed.

NOTE. My MVP colleague and TWCF Mod Corrine adds: JavaRa hasn’t been updated to support the removal of JRE 7 and seems to have trouble past JRE 6u32. It has moved to SingularLabs.com. In addition, Paul McLain no longer supports JavaRa, but Freð ðe Vries still does.

Java Download

You can download and install Java for Windows manually from Java.com here.
