When you install or reinstall a Games for Windows, Microsoft Streets & Trips, or Microsoft MapPoint program, you are prompted to enter the product key. The product key is used during Microsoft software installation to "unlock" the product. If you do not enter the product key when you are prompted, the program may not start, or it may work only for a limited number of times.
This article describes where to find the product key. It also describes how to obtain a replacement product key if the product key is obscured or lost.
