Prank Tutorial: Making a "Shutdown in 120 Seconds" Button

Requirements:
A Windows XP/Vista Computer

This tutorial is quite simple.

First: Right, click at the Desktop. Choose "new"
Choose "Shortcut"
Now write: shutdown -s -t 120 -f (Note: the -t 120 can also be set to 2 or 3800. It is the number of seconds it waits before shutting down! If you want it to shut down immediately just delete that part)
Click Next.
Write something innocent like:"Internet Explorer" or "My Documents"
Now it looks just fine, but if someone is going to click that, it will need an icon.
Right click the Shortcut. Choose "Properties".
Choose "Change icon".
Click "Ok" to that little Popup, and choose an icon.
Click "Ok" and "Ok" again.
