So i come across this every now and then where i have a machine that successfully had the software installed, but through an automatic update or user removing it the software needs to be reinstalled. Wouldnt it be great to be able to just push out the GPO to that user again? Well you cant exactly… If you redeploy a GPO software from GPMC it will force a reinstall for everyone. Below are the steps you need to do.

Who hates Java? (how to remove all Java installations on your Network)
My colleague who is rightly paranoid about security has a dislike for the buggy software from Java, so one 
day he shoots me off a link to a forum where he found a VB script to remove ALL versions of java from a PC. Fantastic i thought, now we just have to put it in our environment!
Here is the forum from where we got a VB script from:
http://www.appdeploy.com/messageboards/tm.asp?m=29809
So they guys on the forum post did all the hard work, all I did was apply it to our situation. Here is what we wanted to achieve:
- Run the script on every PC (client) in our network – we didnt have alot of users that actually required Java so we decided to remove everything, and only install it (in a managed way) to the users that required it.
- Make sure the whole script did not run EVERY time the PC was turned on.
- Output the log files somewhere centrally so we can monitor the uninstall process.
- Provide a managed Java deployment solution via GroupPolicy
