Key Management Service (KMS) activation is a method of activating software products developed by Microsoft, such as Windows and Office. The principle behind KMS activation is relatively simple: it involves the use of a KMS host server and a KMS client.

Large organizations use the KMS activation method using GVLK keys, which need to activate several copies of software products at the same time. With K M S activation, organizations can activate hundreds or even thousands of copies of software products without having to activate each copy individually.

One of the benefits of KMS activation is that it is a permanent activation method. Once a product is activated using KMSactivation, it will remain activated even if the computer is disconnected from the network. Additionally, KMS activation does not require the use of a physical product key, which makes it easier for organizations to manage their software licenses.

In summary, KMS activation is a method of activating Microsoft software products that is commonly used by large organizations. It involves the use of a KMS host server and a KMS client and is a permanent activation method that does not require the use of a physical product key.
