Firstly, taking the KMS activation mode makes the activation of Windows/Office more stable; Second, KMSOffline has a very simple way to operate - one click activation. In addition, it is able to effectively activate almost all products of Windows desktop, Server, and Office; the activation action can be performed from an embedded KMS service, or from a public server on the Internet/LAN; supports installing GVLK keys for all Windows products; allows user to view the activation relevant information (including system, SKU ID, expiration date, etc.); provides multiple startup parameters, and more.
KMSOffline has minimal settings, so that even the most inexperienced user can easily activate Microsoft's Windows, Server or Office products, and get a licensed product with a normal key. The activation process is performed either from the embedded KMS-Service, or from a server on the Internet/LAN. And, the option "Install KMS-Service" will install a KMS server emulator into the system, in order to activate your Microsoft product locally and automatically.
