Original title: Windows 10 messed my computer very badly.
Sooo I went from a real copy of Windows 7 to Windows 10. I decided I didn't like it and went to back because i couldnt get over half my programs to work for it so I went back to Windows 7 and now its saying I have copy that's not genuine. I cant redownload Windows 10 again since its "Not a Genuine Copy". Im now just sitting here with that not being able to do anything. Im not sure if this is a common problem or not seeing as I couldn't really find anything about it.
