We send PC's out to customers that need a very specific version of Java installed; specifically 6.26. I already disable the Java updater but I was wondering if I could block the customer from installing a new version of Java manually without forcing them to run as a limited user. Currently, the PC's run as local administrators with Windows 7 64-bit.
Perhaps an application that provides a blacklist functionality? I also use the IE9 Blocker Toolkit to disable Internet Explorer 9 installation. Is there a possible equivalent for Java?
Edit based on comments - Java is used with a java applet on our website, not a standalone application. I have no power to alter our site to be compatible with newer version of the software. I'm simply trying to limit the ability to update Java to cut down the amount of support calls.
