PIDs and Product keys

PIDs and Product keys

A PID is created after a product is successfully installed. PIDs are used by Microsoft Customer Service to help identify the product when customers engage Microsoft for support. A Product key is a unique combination of numbers and letters that is used during Microsoft software installation to "unlock" or open the product. If you do not enter the product key when you are prompted during the installation, the product may not open until you enter the product key.
More information about how to identify, locate, and replace a product key.
