To use the keys listed here (which are GVLKs), you must first have a KMS host running in your deployment. If you haven’t already configured a KMS host, see Deploy KMS Activation for steps to set one up.

If you are converting a computer from a KMS host, MAK, or retail edition of Windows to a KMS client, install the applicable setup key (GVLK) from the following tables. To install a client setup key, open an administrative command prompt on the client, type slmgr /ipk <setup key> and then press Enter.
