I have a Windows 2012 Server Standard with an OEM licence key. This server is an Hyper-V host with only 1 VM on it.
I just installed a new VM with Windows 2012 R2 Standard but the server won’t activate the licence.
Is there a way to activate it the way it is? or is the only solution upgrading my host to R2 (i would prefer not to since i can’t reboot easily) ? Using the OEM key i got with the host doesn’t work.
