I just upgraded to Windows 10. There were a bunch of issues so I went back to Windows 7 to see if it solved it. And it did. But I had to replace my motherboard but there are new issues on Windows 7 (related to sound) so I went back to Windows 10. But I don't think it's going to happen bcause it won't have a key. But I do have a stored key in the cloud. Would that work?
