Is it possible for me to buy for example Windows 7 Professional to do a clean install? I currently have Windows 7 Ultimate. I've tried to do a factory reset, I need a disk and I don't have that. I've tried to do a clean install by installing Windows 7 as an ISO-file from Microsoft but for some reason my product key isn't working. I've decided that I wanted to buy a whole new Windows. But will that work? Can I buy Windows 7 Professional to do a clean install?
Edit: I have no idea how to put this in the right topic so if a mod could do that for me that'd be awesome
