Convert Windows Server 2012 Evaluation to Retail/OEM Keys

The first thing you need to do is determine your currently installed version. From an elevated command prompt, run the following command:

DISM /online /Get-CurrentEdition

You will see something similar to the following:

C:\Users\Administrator>DISM /online /Get-CurrentEdition
Deployment Image Servicing and Management tool
Version: 6.2.9200.16384
Image Version: 6.2.9200.16384
Current edition is:
Current Edition : ServerStandardEval
The operation completed successfully.

Look for the line that starts with “Current Edition:” and take note of the exact text minus the Eval at the end. It will either say ServerStandardEval or ServerDatacenterEval.

Now with your license key in hand, run the following command:

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

Reboot the server when prompted.

When it comes back up, you will notice that the text in the bottom-right corner of the wallpaper no longer says evaluation. Go to the Control Panel, System and activate your server. It should all go through smoothly and be ready to go now.
