Is your friend silly enough to leave you alone with his computer? Whether it be to use the bathroom, grab a snack, or make-out with his girlfriend, it gives you an awesome opertunity to pull one of the best pranks in computer history on his ass.
As soon as he leaves, go to his desktop and create a shortcut. The shortcut manager will pop up and ask you what you want the shortcut to link to. In that box, instead of typing the file path of an .exe, type the following:
Code:
%windir%\system32\shutdown.exe -s -t 60 -c "Hahaha! Good luck getting out of this one!"
When your done with that, name the shortcut "System Test" and move it to Start>All Programs>Startup.
Next time your friend logs into his computer (and everytime after that, for that matter), he'll have a 1 minute warning of his computer being scheduled to shutdown
VERY evil. VERY fun. And since it only happens when you first login, he won't notice it until your long gone
