I havent really hacked them but its real fun to mess around with em. I downloaded Avant Browser and that fucked up everything. I also go to Windows Task Manager and shut down a bunch of processes. I download abunch of programs and keep em hidden in the S drive aswell. Everyone in my school are idiots so they dunno what im doing on there. I did manage to download Gunz: The Duel on there and play it during lunch, that was shit though cuz our PC's have the shittiest graphic cards and about 250mb of ram. Thats about it, I change the background on occasion or use a proxy site to bypass the restrictions.
