Key specifies the 29-character product key that determines which edition of Windows to install. Use the correct product key for the edition of Windows that you are installing. For more information about using product keys in answer files, see the Work with Product Keys and Activation topic in the Windows® Assessment and Deployment Kit (Windows ADK) Technical Reference.

The product key that you use to activate the installation must match the number on the Certificate of Authenticity (COA) sticker that accompanies the retail product or that is physically attached to the computer case by the original equipment manufacturer (OEM).

Standard licensing agreements specify that you can use a product key only to activate one installation of Windows on one computer. Windows Product Activation enforces this requirement.
