Geez, people are so damn uptight these days.
When I was in high school, the computers in the lab ran Windows 95 and had some sort of security program that blocked access to various websites, disabled regedit, locked out the control panel, disabled the F8 bootup menu, etc.
I rebooted the computer, then shut it off in the middle of booting up and turned it back on again. I got the "Windows failed to start up normally" boot menu which gave me the ability to boot into safe mode. From there I was able to kill the security program and unlock Windows.
The computer science teacher got a kick out of it, and asked me not to do it again. I reinstalled the software, and that was that. I agreed to leave the software alone...and from then on used nslookup to access forbidden websites by IP address, since the blocking software only worked with domain names.
It's a good thing I wasn't born a few years later, or I'd be a felon right now.
