Stop Students Embedding .exe in Powerpoint
We are being plagued at the moment with students playing Minecraft in lessons. We have blocked the .exe from running and have denied any student saving a .exe on their home folders. The little darlings are now embedding the .exe into a Powerpoint presentation then running it from there and it is working. Does anyone know how to block .exes running from within Powerpoint? I've done a Google around and have searched forums but have found nothing that would suit.
We are running Windows 7 32-bit on clients, Office 2010 and our domain is Server 2008 R2.
Any help or ideas would be greatly appreciated.
