Know the Difference between MAK vs KMS in Volume License Key Types in Windows OS – Some people who like to explore licensing issues in the Windows operating system may already be familiar with the term KMS (Key Management Services) or MAK ( Multiple ActivationKey).

In contrast to KMS which is a type of key is quite often we see, some users may still not know and are too familiar with mak key, where indeed this type of license is mostly used in a company only.

Well with regard to that, on this occasion I will explain a little briefly, what is the difference between MAK key vs KMS key in terms of license key type in Windows.

MAK (Multiple Activation Key)

As the name suggests, MAK or Multiple Activation Key is a type of license used for the activation of a certain number of devices, one MAK key can usually be used by many devices depending on the agreement between the license buyer and Microsoft.

For the way of activation itself, MAK is the same as in general, users can enter the slui.exe then enter the key there, after entering, the system will be connected to the Microsoft activation service > verify the key entered and reduce 1 of the number of activations that are still available in the key.

And because mak is limited, then arguably this type of license is not reserved for devices that are often reinstalled, in addition users have to re-enter the key every time they perform a clean install, in contrast to KMS which will usually be activated immediately after the device is connected to the Internet.

Unique fact: if you have ever explored the activation of Microsoft Office or Windows 8 by phone method via Skype, then the type of key used is MAK, therefore in its time MAK key is pretty much sought after by pirated OS lovers who want to feel the sensation of Original with the active period of license forever.

KMS (Key Management Services)

KMS stands for Key Management Services,basically MAK and KMS are having the same scheme where one license is used by many devices, the difference lies in how the system configures and processes MKS activation.

in Windows Vista, 7 or 8, users must configure KMS manually by configuring servers in the network first, because the KMS license type is not connecting to Microsoft licensing services over the Internet but rather is done using DNS to find the Software Licensing server. In Windows 10, you can find out if you’ve ever used the KMSPixx or KMSAutoNxx apps.

In addition KMS can expire after a set period (usually 180 days), and the number of activations will automatically increase on the Software Licensing server and the client will be notified if the system has not been activated and needs to reconnect to the server to reactivate.

This type of KMS License actually has a number of advantages, for example if the device used is connected in the same domain as the server or is a pc inventory of the company, but the lack of users have to activate KMS back manually if it is not part of the company with its private server Licensing Software.

Both MAK and KMS Are Volume License Types

Based on the explanation above, both MAK or KMS are both types of Volume licenses, because indeed one Key can be used by many devices, in other words MAK or KMS is not OEM or Retail.

With this, if you buy a cheap license in the Online Shop you must see if the license they are selling is Retail, OEM or Volume (MAK), because rogue sellers sometimes write down Retail when they sell mak, lay users may not know because either Retail or MAK, both are activated over the Internet and connected to Microsoft activation services, but the difference is very clear, because MAK will not be able to be used after the number or limit of activation of the key is exceeded .

So don’t be surprised, if you use a key that you buy at a low price for activation, and someday you clean install, the key can not be reused.


Using MAK or KMS is not a problem if done in a legal way, such as you get the key from a particular organization or company that you follow.

The problem is when you sell MAK licenses for personal use, or use KMS activation outside of the terms provided by Microsoft itself.

Well again, keep in mind that there are several different types of licenses for Windows operating systems, ranging from OEM, RETAIL and VOLUME, for volume types there are two different sub categories, MAK and KMS, so before buying a license and using it, make sure first those types of licenses so that you are happy and not disappointed in the future.
