I just installed Windows 8 Pro (x64) VL successfully. It is all activated (via KMS) and working fine. Now I want to add Windows Media Center. When I click on add new features. It does not exist! Is it because it is the volume license. If so what can I do then? How can I add WMC??? Please help me as I just got a TV tuner usb stick and I really badly need WMC. I don't mind paying $10 for it. Thanks.
