Volume Activation is a product activation technology that was first introduced with Windows Vista and Windows Server 2008. If a product is not listed, no key is required. Not all Volume Licensing products require a key. Information on how to get your key will be displayed. Look up the product for which you need a key. Learn about Volume Activation and how to activate systems using KMS and/or MAK.

VLKs can be used only with Volume Licensing products they cannot be used with retail software or software that is preinstalled on a new computer (original equipment manufacturer, or OEM, products). Volume License Keys (VLK), including MAK and KMS, are issued to you under a specific license agreement and enable your organization to use the software and products that you have licensed. Planning for Volume Activation needs to be a part of your Windows Client and Windows Server 2008 deployment process. Customers can use either or both key types to activate systems in their environment. KMS allows organizations to activate systems within their own network, while MAK activates systems on a one-time basis, using Microsoft’s hosted activation services.

The first model is Key Management Service (KMS) and the second is Multiple Activation Key (MAK). Volume Activation provides two different models for completing volume activations. Volume Activation applies to systems that are covered under a Volume Licensing program and is used strictly as a tool for activation and is in no way tied to license invoicing or billing. It is designed to allow volume license customers to automate the activation process in a way that is transparent to end users. To activate these operating systems with VA, you can use either a Multiple Activation Key (MAK) or Key Management Service (KMS), requiring a KMS key. With Volume Licensing for products such as Windows 7, Windows Server 2008 and Windows Vista, you must use a new type of product activation called Volume Activation (VA). A product key is required to activate these products. Microsoft includes product activation technology in some products sold through the Volume Licensing channel.
