Can i remove old java runtime updates

Generally speaking, uninstalling older versions of Java is recommended for security reasons and should not impact the programs that require Java to operate I. Java is a widely used programming language that is used on computers, tablets, phones, and even appliances such as your refrigerator.

The beauty of Java compared to other programming languages is that it is cross-platform. This means it can run on different operating systems, whether it's Mac, Linux, Windows, or other devices, without making changes to the Java application itself.

This means you can literally run the same Java application on one machine to the next, regardless of its operating system. 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. You should only have to Approve that one update. I have done what you described above and still can not get it to uninstall Java.

It installs fine but the uninstall is not working at all. Even though this isn't my ideal way this would work I just want something to work in uninstalling old versions. You could also just add the uninstall to the packageboot of the new Java install before you publish it. Ive done it in the past and it works fine. The number after the 2F is the version, so these are for the 64 bit version, for 32 bit its 2FF0.

Hope that helps. I have already tried to add the GUID of the installed version but that does not seem to do anything. In the first screen shot above is where I have the package uninstall being setup, is that not correct?

It looks right. This topic has been beaten to death on this forum. Maybe this thread could help? Yes, I have had success with manually removing java from computers. You can check whether you have Java installed or not in Windows by going to the Control Panel and looking for the Java icon. If you see it there, that means you have Java installed.

I regularly receive messages from the Windows 10 Action Center that there is a new Java update available and that I need to download it due to security updates, which I always do. Therefore, I have four questions: is it safe to remove old Java updates?

If so, which Java updates can I uninstall? Can I remove older Java versions? Is the latest Java backwards compatible with my Java applications? The simple answer is: Yes, it is possible to remove older Java updates, and there is an automated way to do this safely explained below.

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.
