#1. CTRL + ALT + DOWN / RIGHT / LEFT ARROW KEY(as it may please you), flips the computer screen display upside down or left-right, useful trick to annoy a non-computer savvy colleague!
#2. Start Button + L - Short-cut to lock the system, can be done quickly and is annoying when done to an unsuspecting co-worker!
#3.This is a group trick, 2+ more people should be fine. Decide on a colleague and one of the conspirators may hit the Shift Key on the system 6times giving out a very funny sound out of the inbuilt mono speaker in the Cabinet.
As the sound pops out, together stare at the victim colleague quickly for a couple of second and act like naturally ignoring.
Again create the sound and stare longer together, you will find the victim getting un-easy and the situation will be worth a a nice laugh.
#4.This trick may require some time, * To start with take a screen shot of the desktop with icons visible.
(Do the following steps as you read)
* Set the screen-shot as the Desktop Background.
*Now right Click on the Taskbar and untick ' Lock Taskbar ' ( ie-unlock the taskbar ),
*Now you can drag the taskbar up or down and resizr it OR even pull it down completely to make it disaapear!
*Once it goes down only the dummy taskbar and icons will be visible,
* Its enough to frustrate an unsuspecting victim to spend minutes to figure out why the hell is the computer not responding.
*And if you find the victim restarting the apparently non-responding computer you have pulled a very successful trick! ;)
