Change Product Key On Windows Server 2008

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

Do the following.

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

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

…. why not just click the change product key button under system?
for example right click computer, click properties. change product key?
