Hi, Just wondering that if a user as windows 8 pro activated On-line with genuine key & back up the activation data Then adds their free WMC & activates on-line & also backs up that activation If the user then does a clean install of windows 8.1 the restores the activation from the data of win 8 pro then does the same with Wmc key Would the user end up with Windows 8.1 Pro +Wmc Fully Activated Without the need to use phone activation as I`m sure they would be no problems with the data from the windows 8 pro its the Wmc key that causes activation issues But I Google this & some site suggest you can activate one of the free offer Wmc key without using phone activation Can someone explain this method
