Microsoft includes product activation technology in some products sold through the Volume Licensing channel. A product key is required to activate these products.
With Volume Licensing for products such as Windows 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, and Microsoft Office 2010, you must use a new type of product activation called Volume Activation (VA). 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.
Volume Activation is a product activation technology used to activate Windows Vista, Windows Server 2008, 2008 R2, Windows 7 and Office 2010. It is designed to allow Volume Licensing customers to automate the activation process in a way that is transparent to end users. 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.
Volume Activation provides two different models for completing volume activations. The first model is Key Management Service (KMS) and the second is Multiple Activation Key (MAK). 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. Customers can use either or both activation methods in their environment. The type of key entered in the product determines the activation method.
If you plan to deploy Windows 7 and/or Office 2010 using Key Management Service (KMS) as the activation method, please note:
-
Windows Server 2008 is not supported as a KMS host to activate Windows 7 and Office 2010.
-
If you are using Windows Server 2008 as a KMS host, here are your alternatives:
-
Upgrade the KMS host machine to Windows Server 2008 R2.
-
Downgrade the machine to Windows Server 2003.
-
Run the KMS host on a Windows 7 volume edition machine.
-
Run a Windows Server 2003 virtual machine on the Windows Server 2008 machine.
If your organization has fewer than 50 PCs, the best option is to use Multiple Activation Keys (MAK) with Volume Activation Management Tool (VAMT).
While Microsoft makes every effort to cover all of its previous platforms for compatibility, new technologies may make it necessary to decide which previous versions will continue to be supported. Therefore, Windows Server 2008 is not covered as a platform as an Office 2010 KMS host.
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 that you have licensed.
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).
Learn about Volume Activation and how to activate systems using KMS and/or MAK.
Look up the product for which you need a key. Information on how to get your key will be displayed. Not all Volume Licensing products require a key. Volume license products using Volume Activation are pre-installed with a KMS client setup key. You will not need to enter a key for products on your client machine if you are using KMS activation. If a product is not listed, no key is required.
For most products, there are two ways to obtain your VLKs:
If you are using the ISV Royalty Licensing Program, or the High Volume Messaging Services Agreement (HVMS), keys are not available through the Volume Licensing Service Center (VLSC); you will need to request them by calling your Activation Center.
Some products licensed under Volume Licensing agreements use keys that cannot be obtained through the VLSC or the Microsoft Activation Center.
Keys are assigned to and intended for the sole use of your organization. You may be held responsible for unauthorized use of VLKs issued under your agreement, so be sure to keep your keys secure and do not disclose them to unauthorized parties. If you use the VLSC, you should regularly review and update the user permissions.
