What is volume activation?

Volume Activation is a configurable solution that helps automate and manage the product activation process on computers running Windows operating systems licensed under a Volume Licensing program. Volume activation is also used with other Microsoft software (mainly Office suites) that are sold under volume license agreements and that support volume activation.

  • Tools to manage Office volume activation
  • Volume Activation for Windows 10

Volume Activation applies only to systems covered by a Volume Licensing program and is used strictly as a tool for activation. It is not tied to billing or license billing.

Volume Activation offers two different models to complete volume activations. Customers can use one or both of these key types to activate systems in their organization:

  • Key Management Service (KMS)allows organizations to activate systems within their own network.
  • Multiple Activation Key (MAK)activate systems once using Microsoft hosted activation services.


As part of the installation, it is important to plan and manage the deployment of any product using Volume Activation.

What is the Key Management Service (KMS)?

Key Management Service (KMS) is an activation service that allows organizations to activate systems on their own network, eliminating the need for individual computers to connect to Microsoft for product activation. It does not require a dedicated system and can easily be hosted on a system that provides other services.

KMS requires a minimal number of physical or virtual computers in a network environment. These minimums, called trigger thresholds, are set to be easily met by enterprise customers.

  • Activation limits for Windows
    • Your organization must have at least 5 computers to activate servers running Windows Server.
    • Your organization must have at least 25 computers to activate client systems running Windows.
  • Office activation limits
    • Your organization must have at least 5 computers running an edition of Office to activate installed Office products using KMS.

For more information about activation limits, see theVolume Activation Planning Guide.

What is a KMS host key?

One KMS key is used to activate the KMS host computer with a Microsoft activation server and can activate up to six KMS hosts with 10 activations per host. Each KMS host can activate an unlimited number of computers.

No Key Management Service (KMS) key is displayed in VLSC for Open License customers

KMS keys are no longer pre-assigned to open contracts, as the use of MAK (Multiple Activation Key) keys is the preferred method for activation.

(Video) Lightburn FAQ, The Most Frequently Asked Questions

KSM keys can be assigned, by exception, to open clients that meet the minimum KMS activation threshold for Windows Server, OS, and Office. To request such an exception, submit a web form request toVLSC support.

To do this, you must have VLSC Administrator, Key Administrator, or Key Viewer permissions and provide the following information:

  1. Agreement/Enrollment Number or License and Authorization ID.
  2. Product name (include version and edition).
  3. Last 5 characters of the product key.
  4. The number of host activations required.
  5. Business justification or reason for implementation.

Additional KMS Hosts

if you need additional KMS activations to activate more than six (6) KMS hosts, please submit a web form request toVLSC support.

To do this, you must have VLSC Administrator, Key Administrator, or Key Viewer permissions and provide the following information:

  1. Agreement/Enrollment Number or License and Authorization ID.
  2. Product name (include version and edition).
  3. Last 5 characters of the product key.
  4. The number of host activations required.
  5. Business justification or reason for implementation.

What is a Multiple Activation Key (MAK)?

A multiple activation key (MAK) activates systems once through Microsoft hosted activation services (which require connecting to a Microsoft activation server). Once the computers are activated, no further communication with Microsoft is required.


Each MAK has a default number of activations allowed under your Volume Licensing agreement.

The number of Multiple Activation Key (MAK) activations provided does not match the number of licenses we purchased

We recommend that customers use the Key Management Service (KMS) to activate their Multiple Activation Keys (MAKs). KMS is the preferred activation method for large-scale deployments. Many factors determine the number of activations associated with each MAK, including the licenses purchased, the customer's purchase price level, and their Volume Licensing program.

The number of activations available for a product does not always match the number of licenses purchased. Typically, you will receive a higher number of activations if you need to reinstall and activate some of your products. Please refer to the License Summary section of your agreement for the number of licenses.

Requests to increase MAK activation limits must

Increases in the amount of activation of MAK can be requested throughweb formand may be granted by exception. For Canada and the US, useN.America MAK ADD web form

To do this, you must have VLSC Administrator, Key Administrator, or Key Viewer permissions and provide the following information:

(Video) Top 10 Frequently Asked Questions About Selling on Amazon

  1. Agreement/Enrollment Number or License and Authorization ID.
  2. Product name (includes version and edition).
  3. Last 5 characters of the product key.
  4. The number of host activations required.
  5. Business justification or reason for implementation.

How to activate using a multiple activation key

You can activate licenses in two ways using the MAK:

  • MAK independent activation- Each computer individually connects to Microsoft via web or phone to complete activation.
  • MAK Proxy Activation- A centralized activation request is made on behalf of multiple computers with a single connection to Microsoft online or by phone. This method uses the Volume Activation Management Tool (VAMT), which is part of the Windows Automated Installation Kit (WAIK). VAMT enables IT professionals to automate and centrally manage the volume activation process using MAK and includes verification of the number of activations in MAK.

The Volume Activation Management Tool (VAMT) enables network administrators and other IT professionals to automate and centrally manage the volume and retail activation process for Windows, Microsoft Office, and other select Microsoft products. VAMT can manage volume activation using Multiple Activation Keys (MAKs) or Windows Key Management Service (KMS). VAMT is a standard Microsoft Management Console (MMC) snap-in that requires Microsoft Management Console (MMC) 3.0.

Where can I find more information about the Volume Activation Management Tool (VAMT)?

See the following resources for information on VAMT:

  • Volume Activation Management Tool (VAMT) Technical Reference
  • Manage activation using the Volume Activation Management Tool (VAMT)
  • DescargarVolume Activation Management Tool (VAMT)

Can I use MAK and KMS for deployment in my organization?

Yes. Volume Licensing customers can use KMS, MAK, or a combination of each to activate systems in their organization. Customers can use a combination of activation methods as they wish.

How do I determine which key to use for a given product?

See the following resources for help determining which key to use when activating a Microsoft Volume Licensing product:

Read these Microsoft documents on licensing and activation of Windowsbefore deploying Windows or Windows Server. Additional resources include this video onVolume Activation Basics.

Volume Activation for Windows and Windows Server

If you deploy Windows using the Key Management Service (KMS) as the activation method, note that:

  • Windows Server is not supported as a KMS host to activate Windows.
  • A patch is available to allow Windows client machines to activate. (A Windows Server KMS key is required.)

If you are using Windows Server as KMS host, your alternatives are:

  • Upgrade the KMS host machine to Windows Server.
  • Downgrade the machine to Windows Server 2003.
  • Run the KMS host on a Windows volume editing machine.
  • Run a Windows Server virtual machine.

Volume activation for Office, Project, and Visio

Yes, the following Volume Activation changes are related to Office, Project, and Visio:

  • Office KMS Host activates any Office suite or application.
  • Only one Office KMS key needs to be installed and used for activation.

If you deploy Office using Key Management Service (KMS) as the activation method, note that:

  • Windows Server is not supported as a KMS host for activating Office.
  • There is no patch available to enable activation of Office clients.

If you are using Windows Server 2008 as KMS host, your alternatives are:

(Video) 5 Secret ChatGPT Prompts That Build & Market Your Business For YOU!

  • Upgrade the KMS host machine to Windows Server.
  • Downgrade the machine to a previous version of Windows Server.
  • Run the KMS host on a Windows PC.
  • Run a Windows Server virtual machine on a newer version of Windows Server.

Turn on Windows Terminal Server and Remote Desktop Service (RDS)

After you download the media from the VLSC server, you can activate it through the product activation wizard, and you do not need to locate a volume license key or product setup key on the VLSC. Upon completing all the steps of the activation wizard, the server will connect to the Microsoft Clearing House over the Internet to validate the information entered. Alternatively, for offline servers, the activation wizard offers phone activation or web activation as alternatives.

To start the process, you must firstassign a remote desktop license rolefor the server, (from the "Start" menu, go to "Administrative Tools", then "Server Manager") and thenenable RDS service(In Remote Desktop License Manager, click the Start button, select "Administrative Tools," select "Remote Desktop Services," and select "Terminal/Remote Desktop License Manager.)

During activation, you are prompted to select theLicense program and contract number. Note for Open License customers, you must enter your authorization number. For MPSA, enter the purchasing account number (not the MPSA Agreement number). If you are not sure of the program type for the license ID under which your CALs were purchased, go toSummary of VLSC relationshipsand see the Main Program column.

For information on Terminal Server licenses, visitTerminal Server Licenses - Windows Server | Microsoft Documents.For information about installing the Remote Desktop Licensing feature and activating the license server, go toActivate the Remote Desktop Services license server | Microsoft documentsTroubleshooting Cannot connect to RDS because no RD license server is available - Windows Server | Microsoft documents

Organizations within the same ownership structure can use the same key to deploy a product.

License compliance and asset management are independent of key activation. Customers are not required to use keys provided under a specific license ID (contract, registration, affiliate, or license) for use only with the licenses specified under that license ID. If a parent organization (owner of a child organization) has an individual agreement, you can use the same key to deploy a product to both parent and child organizations. This flexibility allows customers to centrally manage their deployment image using either contract/license-specific keys or one set of keys for all.

Can I use my volume license keys to exercise my imaging rights?

Yes. Imaging rights are granted to all Microsoft Volume Licensing customers. Under these rights, customers may recreate licensed copies of the Original Equipment Manufacturer (OEM) or Full Packaged Product (FPP) using the media provided under their agreement, provided that the copies made from the media volume licenses are identical to the original licensed product. As a Volume Licensing customer, the required Volume License keys can be found on the Product Key page. You can also request your keys through aMicrosoft activation center.


If you are an Open License customer, you must purchase at least one unit of the product you want to reimage to gain access to the product media and receive a key.

For more information on image reproduction rights, seearticle on this page about the reinvention of rights.

How do I download my keys to a local file?

The VLSC provides an option to download your product keys to a local file for later use. When downloaded fromDownloads and Keyspage, the file contains all the volume license keys associated with the agreements in your VLSC profile. However, if you download the license ID-specific view keys from the Relationship Summary page, the file will only contain the keys associated with the license ID you are viewing.

A downloadable product key file is in a tab-delimited format and can be opened in Excel to sort and view the keys. You can also preview the file with any text editor. The columns included in the file are: License ID, Parent Program, Organization, Product, Product Key, Type, and MAK Activations Used/Available. To open a downloaded file in Excel, complete the following steps:

  1. Abra Microsoft Excel.
  2. CliqueArchiveand soOpened- select the downloaded CSV file.
  3. selectdelimited(default) and then selectseparated by tabs(to avoid displaying all the data in a single column).
  4. CliqueEnd up. The .CSV file opens in Excel and the data is displayed in separate columns.
