Configure KMS for Windows 10

This is a step-by-step guide to configuring KMS for Windows 10 thereby enabling volume activation for Windows 10 in an enterprise environment.

Updating enterprise services to be able to support Microsoft’s latest operating system is at the forefront of most IT Departments and KMS is just one of many.

While configuring KMS has always been a relatively simple endeavour and Windows 8 and Server 2012 have made that process even simpler with the Volume Activation Tools, adding activation capability for Windows 10 is a little trickier.

First and foremost it is important to note that volume activation for Windows 10 is only available for KMS running on the following operating systems:

  • Windows 8
  • Windows 8.1
  • Windows 10
  • Windows Server 2012
  • Windows Server 2012 R2

While this blog post assumes you are already running KMS on one of these operating systems, if you are not, you must install Volume Activation Services on one of the above operating systems before proceeding.

It goes without saying that Windows 10 Volume Activation Service supports Windows 10 activation natively, however if you’re running KMS on previous operating systems you must install the following hotfix to add support:
Update that enables Windows 8.1 and Windows 8 KMS hosts to activate Windows 10

After you have installed the hotfix, you must reconfigure Volume Activation Services with the KMS key for Windows 10.

For Server 2012 and 2012 R2, the KMS key for Windows 10 is hidden away in Microsoft Volume Licensing Service Center:

  • Login to MVLS
  • Click the ‘Licenses’ tab and then ‘Relationship summary’


  • Select your current agreement
  • Click the ‘Product Keys’ tab
  • Find the product ‘Windows Srv 2012R2 DataCtr/Std KMS for Windows 10’


To reconfigure Volume Activation Services with the new product key you can use the slmgr.vbs command:

  • On the KMS server
  • launch command prompt as Administrator
  • run slmgr.vbs /ipk insertkeyhere
    You should receive a message stating “Installed product key successfully”
  • run slmgr.vbs /ato
    This will activate the product key over the internet
  • run slmgr.vbs /dlv to see the newly installed product key

Your KMS server is now configured to activate Windows 10!


  • Kriss ! You saved my day ! I can only say that you are the first to show WHERE to find this @#&%° key on VLS. I had no idea where to find it, searched on MS technet, nada. Finally I found your site and “voilà!” My W10 machines can activate. Thanks again.
