Adobe Flash and Java are two downloads that most of us have installed on our Windows computers because they provide us with a richer Internet and browsing experience. We have already seen how to manage Adobe Flash settings. Today we are going to learn about Java settings in Windows 10/8/7.

What is java

Java is a programming language and computing platform that powers advanced programs including utilities, games, and business applications. It allows you to play online games, chat with people around the world, view 3D images, etc.

Java Control Panel

Java Software or Java Runtime Environment is also known as 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 the control panel and click on Java. Here you will be able to get version number information and also view the files.

Delete temporary java files

When browsing the Internet, whenever your browser uses Java, Java files are stored in special folders for faster execution later.

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

By default, these temporary java files are stored in the

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

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

You can view the files by clicking on the Seen button.

To delete these temporary Java JAR files, click Delete files. You can now select the files you want to delete and click OK.

Clear Java cache using command line

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

javaws -uninstall

Java update

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

You can configure Java update settings by clicking the Update tongue.

Make sure the Check for updates automatically is checked. By clicking on the Advanced The button will allow you to set the frequency of update checks.

By the way, I noticed that it’s been a long time since I’ve updated Java. So I clicked on Update now to start the update process. It starts the juscheck.exe process, which will check if an update is available and notify you accordingly.

Clicking Install will start the update process. When finished, click Close.

Other Java Settings

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

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

the Advanced The tab allows you to configure other settings.

Uninstall older versions of Java

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

Old versions of SunJava (up to JRE 6 update 7) indeed remained when the updates were installed and should be removed as older versions of SunJava are very vulnerable to Winfixer/Vundo. It took from 2005 until late last year’s release of SunMicrosystems JRE 6 Update 10 to Sun Microsystems for SunJava’s autoupdater to uninstall previous (vulnerable) versions of the program . Updates from JRE 6 Update 10 are in a standalone “jre6” folder which gets overwritten if a new JRE is installed. Even when using the most recent version of SunJava, if older and vulnerable versions are still on your computer, it is vulnerable to infection. Unfortunately, simply using Add/Remove Programs to uninstall older versions isn’t completely effective.

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

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