Hey everyone, this is a really nice prank for a computer with multi users with the same account!
Ok, the first thing you have to do is to close all running applications.
After that, press “Print Screen” on your keyboard, Open Ms Paint and press Ctrl + v to paste the screenshot.
Save it in a place where no one will see it.
After that set the image created as the wallpaper.
Right click on any unused place on the desktop and go to “Arrange Icons by”, go down until you reach the “Show destop icons”, uncheck it.
Now for your taskbar drag it completely down.
There you go. 😀
The person who is sitting on the computer will start clicking on all the icons but nothing will open with him, not even the start button.
