Hello together,
today i want to show you a script of mine which removes Java from the computer. It makes no compromises and removes really everything of it. At least every relevant file and registry entry which i had found to that point.
But why? And why the hell so complicated?
Java – to be honest – can be very hard to debug. Sometimes an older file is loaded in the background or registry keys have been modified by a program or person previously. So this script creates a nearly green state.
Afterwards you can reinstall a new Java-version again if needed.
It will fix nearly all problems with missconfigurated or missinstalled java versions and at least it will create a state where you can debug still existing problems easily.
Because of deinstalling MSIs the script surely has to be run as Administrator. (rightclick – Run as Admin)
In some cases the script has to be run twice and also in very rare cases the system has to be restarted before installing a new version.
But enough said.
It exists of 2 files which can be found here: GitHubLink
The execution file JAVA_Cleanup.bat and the keyfile KEYS.ini.
JavaCleanup.bat:

and the Keys.ini – from this file the existing substrings of the Installation-GUIDs of Java were inserted. Till now all Java versions up to Java 8 will be deinstalled.

If you have any questions or critique please provide me with feedback.
Keep in mind that we fixed nearly every Java-problem by using this script on a client range of 30000 clients with Win 7. Therefore give it a try if you have also problems with Java!
And now – have fun cleaning the mess up! 🙂
Greetings,
David
