Here's a quick and easy prank that's sure to get a few laughs. I pulled this together in a matter of a few hours between meetings at work. It's very simple, so you should be able to quickly understand and customize it. Basically, on startup, the hapless user will see a familiar error message box that they can't close, and that spawns more and more error messages each time they try to close it. I tried this on my husband and it wasn't until the third error message box that he caught on!

To deploy

Simply copy the executable file (or a shortcut to it) to the Startup folder (C:\Documents and Settings\All Users\Start Menu\Programs\Startup) on the victim's machine and watch the fun begin when they start up their machine in the morning!

Ideas for Customization

  • Customize the text messages to your specific work situation or victim.
  • Add more forms.
  • If you're mean, don't allow the user to close the app at all and constantly rotate between forms.
  • For a more subtle approach, create a Windows service so that error messages pop up at random time intervals during the day and then disappear automagically (as soon as your victim gets Help Desk on the phone)!
