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.
