In university, for some strange reason, we were required to spend a few hours in a 'learn how to use a search engine class.' It was brutal, they used remote control software and slowly and painfully taught us how to use google.

I figured out pretty quickly you could Ctrl-alt-delete to bring up the task manager and just close the client on the computer I was using.

The teacher never figured out why one of the computers vanished off the remote software management screen she was using.
