Just For FUN ;-)

Just for fun :

Try this naughty trick on your friends PC. Close all
the open applications. While you are on the Desktop,
press Print Sceen key. Open Paint and then paste the
captured image. Save it as BMP, right - click on the
desktop and change the wallpaper to the newly saved image.

Go to the "Web" tab of the Display propeties dialog and
turn on Active Desktop. Make sure that the "Hide icons
when desktop is viewed as Web-page" is turned on. From
now on, your friend wont be clicking an application icon
on the desktop, just a picture of it. See their face when
thet happened! :-)
