Change Product Key On Windows Server 2008

If for some reason you can’t change the product key of your Server 2008 under the My Computer Windows Activation option:

iWindows Activation

Do the following.

  1. Open the command prompt and change working directory to System32 directory
  2. Type in slmgr.vbs -ckms (this clears and KMS entry you may have)
  3. Type slmgr.vbs -upk (this removes any product key installed)
  4. Type slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (where the x’s is the new product key you want to use )
  5. Type slmgr.vbs -ato (this activates the server)

after doing that, Windows Server 2008 should show up as activated.
