For your entertainment, RJL Software has something for you to prank your friend or coworker, it’s an EXE called the Vista Upgrade Prank.

The Vista Upgrade Prank starts by emulating the Windows Update service screen followed by what appears to initiate the Vista Upgrade Advisor. It will scan the system (actually does nothing) to ensure the computer is ready to upgrade to Vista, it completes within 15 seconds and informs the user their computer is able to run Windows Vista.

The prank utility enters a ‘fake’ Upgrade mode for a while with lots of flashy icons and flavor text about the wonders you’ll experience in Vista. After closing the upgrade a full screen Vista logo appears with the Vista startup sound making it appear as though the system is running the new OS. After some load time the user is presented with a Mac OS X desktop with a little bit of Windows flavor.

Enjoy, you can download it here.
