Oh man, this takes me back to middle school. Had gotten my first laptop, an amd box running 64bit vista, and man were those bundled parental controls fun. I probably wouldn't have gotten into computing as much as I am if I hadn't gotten so pissed off at the restrictions UAC and parental controls enforced. Ended up booting linux off a slider phone's sd card while in usb mode just to use chntpw and promote myself to admin.
On the side I also did that to my cousin's computer and while my parents didn't care much anymore that I had did that to my own, boy was my cousin's mother pissed. On the bright side of that, I actually earned a good amount of how the registry works and the SAM hive.
