3 Prank's

Format C:

Formatting is what users are very afraid of. Go to RJLSoftware and downloadFakeFormat. The title is self-explaining: It'll look like as if you're formatting your PC. Additionally, the creators from this program disallow the functionality of shutting down. Double trouble!

"The Finger"

And while you're still at RJLSoftware don't forget to download The Finger. This little program will change your cursor into another finger and you'll already have guessed which one it is. Make sure you check the command line options. Place the EXE file in de startup folder of your PC and wait untill other users find out.

Haunted DVD-/CD-Player

Software can have control over hardware. If you used Nero, you'll probably noticed that, when you're done coping a CD / DVD, the CD / DVD will be ejected automaticly. Why not make use of this function? Go to cd-eject-tool.com and download the program. The specialty about this program, is that you can create shortcuts that directly drive the program. Create a shortcut that opens the CD / DVD drive and put it in the scheduele and wait for your victim.
