Okay, so I upgraded to Windows 10 from Windows 7. I had a GA-G41M-ES2L which is not compatible. But when I was installing it, they said that I was safe to download it. Anyways. my 30 days limit to go back is over. Is there any way I can revert to Windows 7? Can I download Windows 7 and then use the same product key that I have now in Windows 10? Remember, I upgraded from 7. Thanks for any sort of help!
