The Microsoft Volume Activation Management Tool (“VAMT”) is part of Microsoft Volume Activation 2.0 and allows organizations to manage the activation of their Windows Vista and Longhorn Server computers using Multiple Activation Key (MAK) keys.

A MAK performs a one time activation of computers against Microsoft. Once the computers are activated they require no further communication with Microsoft. The number of computers that can be activated with a specific MAK is based on the type and level of the organizations's volume license agreement with Microsoft.

MAK Independent Activation: Each computer individually connects and activates with Microsoft either online or via telephone

MAK Proxy Activation: One centralized activation request on behalf of multiple computers with one online connection to Microsoft

Activation Status: Ability to determine the activation status of Windows Vista and Longhorn Server computers in the environment

Remaining MAK activations: The current remaining activations associated with a MAK key

XML Import/Export: Allows for exporting and importing of data in a well formed XML format to enable activation of systems in disconnected environment scenarios

Local reactivation: Enables reactivation of computers, that has been previously activated using MAK, after rebuild or reimage by applying the Confirmation Id

Multiple Activation Key (MAK) REQUIRED: In order to use VAMT, a valid MAK is required. MAK keys can be obtained from the Microsoft Licensing portals by customers with a valid Volume License Agreement. For more information see the Microsoft Volume Licensing website.
