Of course, since I've formatted my work machine and installed Linux without a user-login for our Internal Systems team (they refused to let me have Windows admin-access, so it was the perfect way to get around it - I now have admin-access, they have no access), they have no way to get onto it to check what's installed anyway...
I look after part of the gaming-network in work, which means I need to have a few games installed on my work machine......can't complain, really!
