Before you can move to Windows 8 Pro with Media Center, you will need to retrieve your product key using your PIN. To do so, please follow these steps.
Enter your 27 character alpha-numeric PIN found inside your product key card. See diagram for PIN location. Note: Your PIN is not the same as a product key and cannot be used to move to Windows 8 Pro with Media Center.
The PIN is a 27 character alpha-numeric code printed on the back of the card located inside the package.
