KMS and MAK

hi

What are differences between: KMS and MAK in the Microsoft Volume Licensing?

[Ali · Accepted solution]

Hi Chris,

KMS : KMS requires a minimum number of either physical or virtual computers in a network environment

MAK : Each MAK has a predetermined number of allowed activations, based on your Volume Licensing agreement.



KMS is a lightweight service that does not require a dedicated system and can easily be co-hosted on a system that provides other services. With KMS, you can complete activations on your local network, eliminating the need for individual computers to connect to Microsoft for product activation.


A Multiple Activation Key (MAK) requires computers to connect one time to a Microsoft activation server. Once computers are activated, no further communication with Microsoft is required. There are two activation methods for MAK:

MAK Independent Activation: Each computer individually connects to Microsoft via the web or telephone to complete activation.

MAK Proxy Activation: This method uses the Volume Activation Management Tool (VAMT), which is part of the Windows 7 Automated Installation Kit (WAIK). One centralized activation request is made on behalf of multiple computers with one connection to Microsoft online or by telephone. Note: VAMT enables IT professionals to automate and centrally manage the volume activation process using a MAK.
