I was at a school which used "Lockdown Browser" to try to lock-down the Windows environment to only the exam.

Unfortunately for the school, I had experience with Windows programming, and blew the doors off Lockdown Browser in about 10 minutes, with multiple apps and windows open on top of the befuddled browser. And later, I found a way to do it with no programming skill at all.

I did it to make the point that if I could figure it out, who is to say that some rich student's parents wouldn't pay a nice sum of cash for an exploit like that? Or that they haven't? The school, well... just decided to ignore it and keep it anyway because it was a contract.
