Get help to find your Windows product key and learn about genuine versions of Windows. You will need to use another method of activating Windows, such as using a MAK, or purchasing a retail license. If you want to activate Windows without a KMS host available and outside of a volume-activation scenario (for example, you're trying to activate a retail version of Windows client), these keys will not work. If you don't already have a KMS host, please see how to create a KMS host to learn more. They only work in conjunction with a KMS server.To use the keys listed here (which are GVLKs), you must first have a KMS host available on your local network. Note: You cannot use a GVLK by itself to activate a Microsoft product. In the table below, Windows versions ending with "E" are the international versions, and those ending with "N" are the versions without Windows Media Player. If you are unsure of the exact version of Windows, click on the Start orb, right-click Computer, and select Properties from the menu that appears. You'll use the appropriate GVLK to update installations of Windows that used MAK activation to the new (November 2010) MKS activation method.
