VHDMP-X63PK-3K798-CPX3YWindows Server 2008 R2/2012 contains a command-line utility called DISM
(Deployment Image Servicing andManagement tool). This tool has many features, but one of those features is
the ability to upgrade the edition ofWindows in use. Note that this process is for upgrades only and is
irreversible. You cannot set a Windowsimage to a lower edition. The lowest edition will not appear when you run
the /Get-TargetEditions option. If the server is running an evaluation version of Windows Server 2012
R2 Standard or Windows Server 2012 R2Datacenter, you can convert it to a retail version as follows:
If the server is a domain controller, you cannot convert it to a retail version. In this case, install an
additionaldomain controller on a server that runs a retail version and remove AD DS from the domain controller
thatruns on the evaluation version. From an elevated command prompt, determine the current edition name
with the command DISM /online /Get-CurrentEdition. Make note of the edition ID, an abbreviated form of the
edition name. Then run DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXXXXXXX-XXXXXXXXXXXXXXX
/AcceptEula,providing the edition ID and a retail product key.
The server will restart twice.
