I have build a Windows 2012 DC cluster now I found out that It supposed to be a Standard edition with only one VM on it.
Is there any way I can downgrade from Windows 2012 Datacentre to Standard?
I have tried
DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
slmgr -upk (this removes the current Product Key)
slmgr -ipk XXXX-XXXX-XXXX-XXXX (this installs the new Product Key)
but no success.
