I have a Windows 8 Single Language, then under System, I used the "Get more features with new edition of Windows" then entered the product key of Windows 8 Pro that I got from Dreamspark.
Now, I open App Store then try to update to Windows 8.1 then it say's "Windows 8.1 Single Language Pack" not Windows 8.1 Pro or something so there is an error saying "Your Windows 8.1 install couldn't be completed. Something happened and the install of Windows 8.1 can't be completed."
Is there anyway to revert back to Windows 8 Single Language Pack and Update to Windows 8.1 Single Language pack ?
By the way, when I was in my Win 8 Single Language and tried updating to Win 8.1, it downloaded and I cancelled it because it's not Win 8.1 Pro.
