Just wondering if I am able to install and activate using just my WMC key in future rather than having to install 8 first, then upgrade to 8.1 then upgrade to 8.1 WMC? Is there an 8.1 WMC iso available? The keys I own are a Windows 8 upgrade from 7 (from the special offer days) and a WMC key purchased from 8.1 (upgraded from my Windows 8 key)
or else you can use my ToolKit to Convert a Windows 8.1 Pro Retail ISO to Windows 8.1 Pro with Media Center Retail ISO and Use your Legal Windows Media Center Key to Activate the OS. Also you can Make a Pre-Activated Windows 8.1 Pro with Media Center Retail ISO. Check my signature for the ToolKit Link.
