The best wallpaper

This may look like a long procedure but its simple and worth the effort...

Open any program the your friend often use...

Eg:

Internet explorer(Any program)

Press the button Print screen in your keyboard ...

This is used to take a screenshot.
Now open any image editor(paint is enough... Start->all programs->accessories->Paint)
Press Ctrl+v ie. paste or Edit->paste

Save the file any where and in any name ...



Now, the fun part..
Open the image right click on it and set it as desktop background(Or the work around
Right click on an empty area on the desktop->properties->Desktop->browse and select the image and click apply)

Right click on the taskbar and Deselect lock the taskbar...
drag down your taskbar so that it hides at the bottom of your screen ...

You need to hide or move all the icons from the desktop to some other place

Now watch your friend struggle with his mouse and alt+ctrl+del
