I bought a "copy" of Windows 7 Ultimate from overseas that turned out to not be genuine.
Without having to reinstall, can I purchase Windows 7 Professional and authorize my current windows 7 Ultimate install? When I enter my new product key, will Windows 7 know it's a Professional key and disable the ultimate features (which I never use)?
I'm looking for a solution that means I don't have to spend the extra money for Windows 7 Ultimate without having to go through a reinstall.
Any help is greatly appreciated.
