Issue Adding Windows 10 LTSC 2021 Licenses to VAMT

Question

I have a stand alone VAMT installation on a Server 2019 machine that I use for testing Windows/Office deployments and use MAK keys exclusively (via my Visual Studio Enterprise Subscription) to VMs and networked devices. This is NOT a KMS server.

My VAMT instance hosts license keys for Windows 10, 11, and Server + LTSB2015, LTSB2016 and LTSC 2019 just fine. However - this morning I attempted to add two new key for Windows 10 2021LTSC - VAMT gives me the standard error that this license key is either invalid or not supported by this version of VAMT.

VAMT is fully to date (as part of Windows ADK (v 10.1.22000.0) and the keys should be valid as it came straight from MyVisualStudio.

Is there a newer version of VAMT that I am unaware of?

Thanks!

Answer 1

ADK 22000 is the latest

but LTSC 2021 MAK Licenses were created after that was released
therefore, it doesn't recognize the keys, it also don't support Office 2021 KMS Host keys

you can grab the updated pkconfig files for LTSC 2021 (from the iso install.wim if not installed yet)

C:\Windows\System32\spp\tokens\pkeyconfig\pkeyconfig.xrm-ms

rename to something like pkconfig_win2021.xrm-ms
place the file here

C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\VAMT3\pkconfig

edit ProductKeyConfiguration.man with notepad or any xml editor
and add entry for the new file under the line <ProductKeyConfigurationFiles>

    <ProductKeyConfigurationFile>
      <FileName>pkconfig_win2021.xrm-ms</FileName>
      <ApplicationId>55c92734-d682-4d71-983e-d6ec3f16059f</ApplicationId>
      <ProductVersion>10.0</ProductVersion>
    </ProductKeyConfigurationFile>
