Another KMS Question

I have a KMS server that is used for Servers, Office, and Win10 computers. The issue i am having is with new Windows versions. When I try to add the GVLK fro Windows 10 LTSC 2019 it tells me that the key is invalid or is unsupported by this version of VAMT. I have the latest VAMT (that i know) and the GVLK is correct for sure. Can anyone shed some light on this issue on how to activate LTSC 2019? Any help is appreciated. Thanks

Hi,
There's a known issue from the following link about this:
https://learn.microsoft.com/en-US/windows/deployment/volume-activation/vamt-known-issues
If you want to deploy KMS, it does not have to be VMAT, directly deploy it with command.
Then On the kms server, open cmd as administrator and enter the command

slmgr.vbs /upk
slmgr.vbs /ipk <ProductKey>
slmge.vbs /ato

Hope above information can help you.

Hello,
The user has a Windows 10 KMS key, you cannot install a Windows 10 key on a Windows server machine. Only Windows Server KMS keys can be installed on Windows Server machines.
Windows 10 KMS keys including Windows 10 LTSC KMS keys can only be installed on Windows Server machines.
Windows Server keys will also activate Windows 10 clients including Windows 10 LTSC as long as the the correct Windows 10 Server KMS key is installed.
Please do not suggest using slmgr /UPK, it is not recommended and potentially could cause other issues.
Doing that on a KMS host would remove all the installed keys including Office it the host was also activating KMS Office clients. the KMS history would be lost so the count would have to increment again to able to activate machines.
It is a bad idea to use use the undocumented /UPK switch. that would only be used with suspected corruption in the Trusted store.
