Install a KMS Client Key
You can use the Volume Activation Management Tool (VAMT) to install Generic Volume License Key (GVLK), or KMS client, product keys. For example, if you are converting a MAK-activated product to KMS activation.
Note By default, volume license editions of Windows Vista, Windows® 7, Windows 8, Windows 10, Windows Server 2008, Windows Server 2008 R2, Windows Server® 2012, and Microsoft® Office 2010 use KMS for activation. GVLKs are already installed in volume license editions of these products.
