has anyone been successful in blocking Minecraft through Windows?
I have been struggling to block the JAR files from executing as there doesn't seem to be any way to do it apart from blocking the java.exe which is out of the question.
I have come across this method by Neal Poole https://nealpoole.com/blog/2013/01/h...a-java-applet/ and have been in touch with him via comments but have not yet been successful in implementing a working solution.
If anyone has suggestions or has used a java blacklist file before please let me know.

What about blocking access to the authentication servers?
From my understanding (I don't have a MC account myself though) the new version introduced a mandatory launcher that you have to log in to.
Not sure if it'll work, but might be worth a go!
I ended up just using Impero to block it from running here originally.

We have it listed as a block in Impero but our 'oh so clever' students rename it and still run it!

Many of the kids will run pirated versions - which don't need to authenticate.
Not sure how you'd block it - block all .jar files from their home areas?

The rule I've got is:

Apparently, blocking the .jar files with SRPs doesn't work as it's technically running java.exe then calling the .jar (this is from Googling, not personal experience, so could be wrong!)
If you don't need java for any courses or anything, maybe you could just block java.exe though?

you cant remove java but do you need java to run .jar files or just for some web sites? You could remove javas association to .jar files?
re-associate .jar with notepad?
