Hi all :

  At any time after installing Windows Server 2012, you can run Setup to repair the installation (sometimes called “repair in place”) or, in certain cases, you can convert to a different edition.

  You can run Setup to perform a “repair in place” on any edition of Windows Server 2012; the result will be the same edition you started with.

  For Windows Server 2012 Standard, you can the system to Windows Server 2012 Datacenter as follows:

  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:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula, providing the edition ID and a retail product key.


  And press Enter :
