MAKīoth KMS and Multiple Activation Keys (MAK) are forms of volume licenses but have different use cases. Of course, this violates the terms of the agreement, but no one knows about it except for the organization’s personnel.

Once the KMS server is activated with a host key, it no longer sends out any information over the internet, enabling organizations to use the KSM server to activate as many licenses as required, regardless of their agreement with Microsoft. The client OS rechecks for activation with the KMS server every 7 days, and can reactivate an unlimited number of times. After that, the OS will show messages like “Activate Windows,” or “Your Windows license is expired” if the machine is unable to connect with the KMS server. With a KMS server, a client OS is only activated for 180 days. Remember when we said that the OS needs to “reactivate” itself after a few days? This is what a KMS server is about. Once the GVLK is installed, you must tell your computer which KMS server to contact for activating your OS. For that, a public Generic Volume License Key (GVLK) needs to be installed on the clients, which is unique for each Windows edition. Once the KMS server is activated, other clients on the domain then need to be configured to this KMS server so the products can be activated. Of course, you must already have the host key purchased to find it at the said location. The KMS Host Key can be found on the Microsoft Volume Licensing Service Center at the following location: Microsoft Volume Licensing Service Center > License > Relationship Summary > Product Keys The KMS server can then activate multiple client operating systems, depending on your Microsoft licensing agreement. This key is purchased from Microsoft and used to activate the KMS server deployed within your domain. The role of a KMS server needs to be installed on a Windows Server OS, which can then be activated (once) using a CSVLK, also known as the KMS Host Key. It is used to activate the products which have been obtained through Volume Licensing.
