    More Information

     

    At least one KMS host is needed and you should use KMS client keys to activate your KMS client computers.

     

    After activating a KMS host, the same host can be reactivated up to nine more times with the same key. If you need more than six KMS hosts, you can request additional activations for the KMS key by calling the Activation Call Center to request an exception.
