Can i uninstall previous versions of java

To make the Java application cross-platform, it requires the " Java Virtual Machine " JVM as an 'interpreter' between itself and the operating system. On Windows platforms, the JRE is essentially a single executable file that installs everything you need to run Java applications on your machine. For example, some Windows games require JRE. Although rare, some older Java applications won't run on newer Java releases. As such, it is possible to have more than one version of Java installed on your operating system.

Generally speaking it should be safe to upgrade to the latest Java Runtime Environment JRE for your operating system, then uninstall previous releases using the " Java Uninstall Tool. As each JRE is installed on the machine, Java will prompt to install updates as they become available.

Older updates are not cumulative and can be removed using the Java Uninstall Tool or manually by the user. The Java Uninstall Tool will allow you to select which versions of Java and its updates you want to uninstall.

Generally speaking, yes. It may be difficult to figure out which Java applications you have installed, as Windows does not list which programs are actually "Java applications". I need more questions. If you have a question - or even a computer problem that needs fixing - please email me with your question so that I can write more articles like this one.

Well, the first thing I do when removing Java on Windows is to uninstall the older versions first. To get rid of the older versions, you can download and install the latest version of Java, which will automatically check for older versions and then install the latest version or you can run the Java Uninstall Tool.

The applet will check your version of Java and then remove out-of-date versions. If there are older versions, you will get a message showing you the versions and giving you the ability to uninstall them. Click on the Uninstall Selected Versions button to remove the older versions. Now that you only have the latest version, we can do one of two things: either disable Java or uninstall it. To do this, open the Control Panel, click on Java and then click on the Security tab.

For Firefox, you have to click on Tools , then Add-ons and select Plugins. Click on Java Platform and then click on Disable. Note that even though Java is disabled, it can become outdated and still present a security vulnerability to your computer since it is installed. To uninstall Java, first remove the older versions like shown above and then go to Control Panel and Programs and Features.

Click on the latest Java version listed there and click on Uninstall. Technically, this is all you should have to do, but if you really want to get rid of every trace of Java, I recommend using a freeware app called JavaRa. Once you download it, just run the application. Thanks a lot in advance. Sid Asked 8 years ago views.

Posted by: areiner 8 years ago. Quit be sure to adasdd that "-" infront of the regfiles to be deleted. Comments: Hey Ariner, That was a good one. But is there any way that we can actually do something like a conditional statement where it checks for the registry and delete it. Since it doing to be used on different machines and we are not really sure what version of Java is not installed on the machine.

Over all the script that you gave me is nice. Are you able to pull a software inventory of all the versions of java installed? I do have the inventory of all the versions of JRE.

And it is just version 6 that I need to uninstall. But the folder and the registries that I want to delete are the same. You can confirm that you have the latest version with the Java Verification page or manually checking the Java version.

We highly recommend that you uninstall all older versions of Java from your system.
