Windows is famous not only for being the most widely used OS, but also for its bugs, security issues and blue screens of death, from which not even Bill Gates himself can escape.

Simply download MultiError Pro and unleash your inner imp by designing prank error messages with custom titles, messages and buttons. You can schedule them to appear on the screen at a given time, and also program them to perform a certain action when any of the buttons is pressed. Laugh is guaranteed! Well, except for that of your victim...
