How-to convert Windows Server 2019 Evaluation to Windows Server 2019 Standard

 Hi,

Recently we have bough a new Dell PowerEdge R640 server for my current company, where we have got Windows 2019 Server ROK key.

Since I wanted to use as primary OS Proxmox VE and then virtualize everything I just installed on VM Windows Server 2019 Evaluation Standard on it.

After some test with our company software, I was ready to activate the Windows Licence Key on that machine. The Windows activation procedure via GUI cannot use that key, so from the terminal I have done this:

C:\Windows\System32\DISM /online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula 

Deployment Image Servicing and Management Tool
Version: 10.0.17763.1790

Image Version: 10.0.17763.1790

Starting to update components...
Starting to install product key...
Finished installing product key.

Removing package Microsoft-Windows-ServerStandardEvaluation~31bff3856ad364e35~amd64~~10.0.17763.1

Finished applying edition-specific settings.

The operation completed successfully.
Restart Windows to complete this operation.
Do you want to restart the computer now? (Y/N)

(of course in /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX you have to enter your ProductKey)

After hiting Y the VM machine with Windows Server 2019 Evaluation restarted and stared to clean up some settings:

And after the reboot and login into the Windows Server 2019 I've got this:

And the system has been activated also

And tha't it :)
