Funny Computer Pranks


It is very common for people to play office pranks on each other especially in a laidback setting. As long as the office pranks are harmless and cause amusement they are safe to be employed. However, make sure that you do not play office computer pranks on the wrong person at the wrong time.


  • When you have just a few moments with an unprotected computer, you can quickly surf over to a page guaranteed to embarrass your co-worker, and set it as the home page. Then exit out of the browser, and wait for their reaction next time they go to surf the Web.
  • Unplug the mouse or keyboard of the colleague’s computer while he is away just for a minute. When he comes back, he will find everything nonfunctional, and after cursing his keyboard or mouse, he will check if the connection is all right.
  • Remove the roller ball of the mouse by replacing the bottom cover or in case of an optical mouse you can use invisible adhesive tape to cover it up. When the mouse would not respond, the frustration is worth noticing.
  • Use a double-sided sticky tape to attach the mouse to the mouse mat.
  • Change the mouse controls of a right-handed person to that of a left-handed person. This can be done easily by checking the option "Switch Primary and Secondary Buttons" in the mouse’s properties in control panel.
  • Create incriminating folders on your co-workers desktop, take a snapshot of the desktop, delete the folders, and make the snapshot the wallpaper of the desktop. It will look like an actual desktop and you can have fun watching your colleague desperately trying to remove those folders in vain.
  • Go to mouse settings in control panel and make the cursor speed very fast or very slow. Watching someone drag their mouse across the office to move it an inch on screen is funny! Or you could go to pointer settings and make the default one an hourglass, so they will be left wondering what is keeping the computer busy.
  • Open Microsoft Word and go to Tools > AutoCorrect options. Select the AutoCorrect tab and towards the bottom, you will see Replace and With. Under Replace, type "the" and under With, type "that damn". Every instance of "the" will be replaced with "that damn" as and when your target types it.
  • Enable the Dvorak alternate keyboard layout that even most geeks aren’t familiar with. When they type, everything will go haywire. Head into Control Panel –> Region and Language –> Keyboards –> Change keyboards, then click the Add button and pick the Dvorak layout (or any other random layout you want). Once you’ve done that, use the drop-down above to set the default. You’ll probably want to flip over to the Language Bar tab and set that to hidden as well, so they won’t be able to figure it out easily.

Strange sounds

  • Change sounds on Windows events

    A PC has some build-in audio files that are played when doing something (startup, shutdown). You can change these sounds into something that you want!
    Find the correct audio files in WAV format (Example: Farts, Screams etc.). Save the WAV files to C:/WINDOWS/Media/.
    Go to Start > Settings > Control Panel > Sounds and Audio Devices. Go to the tab Sounds and look for the correct sound in the list that you want to change. Change it by selecting the event and clicking on Browse... Navigate and select your new WAV file and press OK to save.
    You may download collection of sound effects in WAV format here: Farts, Screams, Evil lough, Horror Sounds.
  • Invisible script will play WAV file automaticly.

    Normally, WAV files are played with Windows Media Player. In this joke, you don't want this to happen. We'll write a VBS-file (Visual Basic) that will run audio files that you can't see.
    Open up Notepad and copy the following code:
    strSoundFile = "C:\WINDOWS\Media\[YOURSOUNDFILE].wav"
    Set objShell = CreateObject("Wscript.Shell")
    strCommand = "sndrec32 /play /close" & chr(34) & strSoundFile & chr(34)
    objShell.Run strCommand, 0, False

    Change the [YOURSOUNDFILE] to the sound file you want to play. Now save the file to your harddisk, like this: C:/Sound.vbs. Double-click the VBS file to try if it works.
    You probably want to play these files automaticly. You can do this by creating tasks. Go to Start > All programs > Accessories > System Tools > Scheduled Tasks. A new window will appear. Double click on "Add scheduled task" and follow the instructions. Select your VBS file when the wizard asks if you want to open a software application. You want PC to scream at 9 AM?
