Last state was that I installed Call of Duty 2 to my account, multiplayer didn't work because the no-disc client wouldn't boot.
Well now our teacher has finally realized that his security system sucks and made it harder to install things.
Didn't prevent me from just going into that good ol stationary account again, let it install and copy all the installation files into my school account so i doesnt get deleted.
Basically you cannot get admin perms anymore while youre logged in which interferes with some things but its not too bad really as you can still use the stationary account.
About 1/6 of the school server space has now been used up by people installing steam games, cod2, minecraft and LoL.
Could get funny if the teacher checks the remaining disc space next time because some guys brought TF2 on a usb drive which is ~18GB (note: the server has a collective space of 1 Terrabyte)
