[Server] Windows Server 2012 Evaluation Edition Converted to Legal Edition



We used the trail edition to develop and test new product. Recently we have a valid and legal serial number. But when I tried to enter and activate it. It said "not valid" and not activated.
It's weird to me. So I dig Google and find a way to active it.

  • Go to "COMMAND" line, and type
           DISM /online /Get-TargetEditions

It will show the result like the pic below
The "Target Edition" means you can use either of valid serial key to transfer Evaluation edition to it.

Then, type

DISM /online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula

It will require you to reboot the PC.
