Did you know you can silently uninstall Java from all of your Windows computers? PDQ Deploy has pre-built Uninstall packages in the Package Library for Enterprise-level users, (or, of course, you can write your own uninstall package).
Silently Uninstalling Java
There are three Java uninstall packages available in the Package Library. Each package uninstalls Java installations in a particular family. The three families are: Java 6, Java 7 and Java 8.
Each uninstall package will kill browsers and any currently running Java processes before proceeding to the uninstall. This is generally considered a best practice as you can encounter some nasty errors if a target computer has Java actively running at the time of either an install or uninstall.
