If a product key was not included with your computer, or you think the product key you received may not be genuine, call the Microsoft Piracy Hotline at 1-800-RU-LEGIT if you are in the U.S. or Canada. In all other countries, contact your local Microsoft subsidiary.

Without a valid product key, you may not continue to use Windows Millennium Edition. Click Shutdown to turn off your computer. If you restart your computer after shutting down, Windows Welcome will continue at this point.
