The script can be run locally or remotely on the target computer, using the Windows-based script host The software License Manager ( slmgr.vbs) is a Visual Basic script used to configure and retrieve Volume Activation information. A more complete and well defined list is available here. There are also not official keys for consumer-only versions of Windows that require activation renewal every 45 days (Windows 8.1) or 30 days (Windows 8). The GVLK keys for products sold via volume license contracts (renewal every 180 days) are published on Microsoft’s Technet web site. On the same machine (the KMS server must be a different computer than the client). Also remember you can’t activate Windows 8.1 (and above) on a KMS server hosted For this to work, you have to should ensure that a KMS server is always reachable for all clients on the network.
