Removing Versions of Java on Windows

Sometimes multiple versions of Java being installed can contribute to issues with Java applications. An important step in fixing an issue such as this is uninstallation of older Java versions.

Launch Apps and Features

Search for Java and JDK installations

Important

Be sure to search for both 'java' and 'jdk' in the above step.

Remove all previously installed versions of Java Development Kits and Java Runtimes that are located in the preceeding step.

The uninstallation processes may prompt to reboot the machine. It is safe to continue with additional uninstallations prior to rebooting, but be sure to proceed with a reboot before continuing with a new Java installation.

Note

Ensure any unsaved work is saved prior to rebooting the machine.
