32 Brilliantly Hilarious Ways to Mess With Your Co-Worker’s Computer


Whether you’re at work, school, or home, you can easily take advantage of someone’s unlocked, unattended computer for some wickedly hilarious fun. Note: Please take caution, as while most of these are relatively harmless and innocent, a few are extreme measures only and could actually do harm to a person’s reputation.

On that note, here’s we go!

1. Switch the mouse from being right-handed to left-handed
2. Leave inappropriate pages open in tabs that aren’t in the forefront and wait for them to switch over to them
3. Add a very subtle image to the wallpaper (i.e. a small animal somewhere) then continue to add more on subsequent unlocked occasions
4. Remap the space bar to type “SPACE” every time it’s hit
5. Set the screen saver to lock after one minute of inactivity
6. Take a screen shot of the desktop, set it as the wallpaper then hide the taskbar and all the icons and see how many times they reboot to try and fix it
7. Change the wallpaper to a Blue Screen of Death image and hide the icons; again, count how many reboots it takes to figure it out
8. Complete wallpaper change – not subtle but sometimes appropriate (depending on content)
9. Invert the entire desktop (look for options in the video drivers)
10. Send an email to the team with an offer of free cake or to buy lunch (or other offers of an inappropriate nature)
11. Perform some goating
12. Write yourself an email from their PC on a random topic then reply tomorrow and leave them wondering what they were thinking the day before
13. Change the mouse “pointer” icon to the “busy” icon
14. Leave some very officially titled documents on the desktop with “creative” contents
15. Change the machine language to Turkish (only really effective when the target individual is not Turkish!) and see how hard it is to change back
16. Write a background process to randomly lock the machine throughout the day
17. Change the screen saver to The Blue Screen of Death (yes, that’s a real screen saver) and see how many reboots you get out of it
18. Change the keyboard layout from QWERTY to Dvorak
19. Customize the sounds for common events (choose the level of inappropriateness of the sounds)
20. If the email client supports delayed delivery, write up something to be sent to a large group when you know they’ll be back at their desk
21. Send out meeting invites at inconvenient times and with creative titles
22. Change Microsoft Word auto-corrects, substitute them with foreign language equivalents for extra creativity
23. Open the user’s Facebook and surreptitiously change their birthday to tomorrow
24. Configure the scheduler to randomly launch various apps or open documents at different times
25. Change the path of various shortcuts to point to other apps
26. Rearrange the order of icons on the taskbar (particularly effective if they’re highly organized!)
27. Write a “creative” out of office message and turn it on
28. fdisk – say no more
29. Create a command file to shut down the machine on boot
30. Send a resignation email to the boss
31. Install Windows Vista
32. Tape over the sensor on a laser mouse
