For example, even though your Microsoft agreement states that you have purchased a corporate license for 100 desktop computers, theoretically you can activate thousands of Windows copies (of course, this will be a violation of the Microsoft license agreement, but technically the KMS server doesn’t restrict you in the number of activations). Single KMS server can activate an unlimited number of KMS clients. KMS server needs to be activated only once (you will need to reactivate the KMS server if you want to activate a new CSVLK key with support for the newest Windows versions). The CSVLK key is specified in the KMS server settings and the KMS server is activated on Microsoft servers over the Internet.

KMS server is activated using a special corporate CSVLK key (KMS host key), which can be obtained by any Microsoft corporate customer on the Microsoft Volume Licensing site ( – login the site and go to the Microsoft Volume Licensing Service Center –> License -> Relationship Summary -> Product Keys -> copy the KMS host key for Windows Srv 2019 DataCtr/Std KMS). Desktop and server Microsoft Oss and MS Office can become KMS server clients. KMS infrastructure consists of a KMS server that is activated by Microsoft (this operation is performed once online or by phone) and KMS clients, which send their activation requests to the KMS server.
