MOUSE MALFUNCTION - Stick a post-it note under your friend's mouse so that the paper leaf covers the mouse ball or infrared - the mouse will no longer work! Write APRIL FOOL on the note. Sticky Tape can be used for Infrareds instead.

RESTART - This takes a few seconds alone on someone’s computer. When you get a chance right-click your pal’s icon to Internet Explorer or some other commonly used programme. Edit the properties and change the target to: “%windir%\system32\shutdown.exe -r -t 00″ - Now, every time your friend tries to run IE, his machine will mysteriously restart. Be a friend and help to correct it again! FUN-STUFF-TO-DO tried this one, it didn't work! If you know the correct format let us know! Thanks for the correct format Jeff, it is updated and working! Jeff gave another one, if the PC uses Windows, access the system font through the control panel and set it to white. When your prospect types in a word document or elsewhere on a white background he won't be able to see the typing.

ROTATE - A simple but quick and always amusing prank is putting the screen rotation hotkeys to uses. Hit Ctrl-Alt-up or down to rotate their monitor orientation. If you have some time, you can make this a little worse by going into the Control Panel and setting their mouse to left-handed.

WORKING WORKING - A great mouse prank in the Control Panel. Under the “Mouse” settings’ “Pointer” tab, change the default mouse pointer to the hourglass. Suddenly, the system is always busy working! What’s happening!

SPEEDY - In the “Mouse” settings you'll find loads of fun. Move the pointer speed to either extreme fast or extreme slow to cause a little frustration. We've tried this one on slow and it caused some serious frustration!

FAST! - While your victim is away from his or her computer, change the double click setting on the mouse. To do this, just go to start, settings, control panel and then mouse. Make it so fast that it is nearly impossible to do.

BUSTED - This prank is for that annoying co-worker who is always sending out tons of emails to other workers - All you have to do is go to their email when they are away and set it to "send blind carbon copies" to your boss's email address.

BLACK! - Change the prompt on someone's computer to be black on black. This is rather cruel if the person is computer illiterate. Very effective before a big project is due!

ALERT MESSAGE - Change their Screen Saver to the “Marquee” setting. Go to Start->Settings->Control Panel->Display and choose the Screen Saver tab. Then select “Marquee” from the drop down list. Click “Settings” and enter a virus/warning message of your choice. Then set the “Wait” time to 1 minute. An absolute Good Pranks must do!

ALTERNATIVE - If someone uses Microsoft Word often, go into the computer and change the auto-correct feature so it misspells common words. Just open Word, choose “AutoCorrect Options” from the Tools menu, and have it replace common words like “the” and “and” with wacky words like “eggplant” or “Uranus.” Be creative. We've had great fun with good pranks like this one!
