Server 2019 KMS Host and VAMT doesn't like Server 2019 KMS Keys

Seen on those too! None of the 2019 Keys listed work in VAMT, this is my problem! So Server 2019 Client OS cannot activate against the new KMS Host.

The first one in this list is Windows 10 2015 LTSC.



- - - Updated - - - Clearly there is a massive bug in VAMT because I've tried earlier versions with the same problem. 2019 GVLKs just don't work. Is there another way I can add GVLKs to the KMS Host?

1. Open Command Prompt as Administrator:
   
   • Right-click on the Start menu and select "Command Prompt (Admin)" or "Windows PowerShell (Admin)".
     
2. Remove the KMS Key:
   
   • Enter the following command to uninstall the current product key:
     
     
   • This command will uninstall the current product key from Windows.
     
3. Clear the KMS Server:
   
   • Enter the following command to clear the KMS server name from the registry:
     
     
   • This command removes the KMS server information from the registry.
     
4. Clear the Product Key from the Registry:
   
   • Enter the following command to remove the product key from the registry:
     
     
5. Reset the Activation Timers:
   
   • Enter the following command to reset the Windows activation timers:
     
     
   • This command resets the activation state, putting the system back to a pre-key state.
     
6. Restart the Computer:
   
   • Restart your computer to apply the changes.
     
7. Enter the New Product Key:
   
   • After the restart, open Command Prompt as Administrator again and enter the new product key:
     
     
   • Replace <Your-New-Product-Key> with your official Microsoft product key.
     
8. Activate Windows:
   
   • Finally, activate Windows using the following command:
     
     

If you continue to experience issues with Microsoft Store apps after switching back to the official activation method, try the following steps:

1. Reset Microsoft Store:
   
   • Open Settings > Apps > Apps & features.
     
   • Find "Microsoft Store" in the list and click on it.
     
   • Click on "Advanced options" and then click "Reset".
     
2. Clear Microsoft Store Cache:
   
   • Press Win + R to open the Run dialog.
     
   • Type wsreset.exe and press Enter. This will clear the Microsoft Store cache.
     
3. Re-register Microsoft Store:
   
   • Open PowerShell as Administrator and run the following command:
     
     
4. Check for Windows Updates:
   
   • Ensure your system is up to date by going to Settings > Update & Security > Windows Update and checking for updates.
     

By following these steps, you should be able to switch from a custom KMS server to the official Microsoft activation service and resolve any issues with Microsoft Store apps.

I would kindly recommend refraining from utilizing free Windows activation tools in order to mitigate potential issues such as the one described.
