In this Instructable, I will show you how to play a small prank on your friends. This will make it to where your friend cannot click on anything on the screen. It's pretty basic; most already know how to do this. But, if you don't, read on to find out how to do this.
First, close all of your open windows. If there are a lot of them open, then use Alt+F4 to close them all. Hit the Print Scrn button next to the F12 button to take a screenshot of the desktop.
Open MS Paint. Go to the edit tab on the toolbar. Click paste. The desktop image will be pasted on the screen. Click file+save as+whatever you want+enter.
Now, to save the icons, just cut+paste them into a folder in your My Documents folder. There should be no icons on the screen.
