Volume Activation Services enables you to automate and simplify the issuance and management of Microsoft software volume licenses for a variety of scenarios and environments. With Volume Activation Services, you can install and activate a Key Management Service (KMS) host key, and configure the KMS. After this service is installed, you can also use it to issue, monitor and manage volume licenses for Microsoft products which support Volume Activation in your organization based on computer account information in Active Directory Domain Services (AD DS).
