Try a Joke Program That Upgrade Your System to Windows Vista with Vista Upgrade Prank

The Vista Upgrade Prank starts by emulating the Windows Update service screen. Clicking the install or cancel button closes the update service window and appears to initiate the Vista Upgrade Advisor. This Upgrade Advisor scan the system (actually does nothing) to ensure the computer is ready to upgrade to Vista. If you click the Cancel button, it disables itself. You are unable to close the screen or stop the progress (don't worry, its harmless).
