Got access to someone's computer? Want to wind them up?
Right. Get on their computer, close all the applications and return to the desktop. Press 'print screen', open MS Paint and Press Ctrl+V to get an image of the desktop as an image. Save it, go to the Control Panel and set the saved image as the desktop background. Finally, return to the desktop and place all the apps, folders and so on from the desktop in a single folder. Hey presto! All the desktop icons will remain visually, but be completely unclickable! I've known some IT specialists who've been completely flummoxed by this as there's technically nothing wrong with the machine.

I find it helps (as in, doesn't help much at all) if you name the image of the desktop used in this stunt, "Yeah, I know I'm a cunt".

I've done this a few times on April Fool's Day
It's a classic.

Or
"return to the desktop and place all the apps, folders and so on from the desktop in a single folder."

Instead of this, just unclick 'show desktop'.

add more panic to the situation....
.....before taking the initial print of the screen, create a new folder on the desktop called "Donkey Porn" or "Hairy & Pregnant". Adds a little spice to the proceedings.
