Officially, Key Management Service (KMS) allows organizations to activate systems within their own network, negating the need for individual computers to connect to Microsoft for activation. This process uses a KMS host, which requires its own activation key, and client computers that use special Generic Volume License Keys (GVLKs) provided by Microsoft. The mechanism relies on a client-server model where clients must periodically renew their activation, typically every 180 days. Unofficial KMS tools, including many versions of activation helpers, simulate this environment locally or point the operating system to a public, often unauthorized, KMS server to fraudulently activate the software.
