I updated from Windows 7 Professional N to Windows 10 Professional N successfully and I am fully activated. If I choose to re-install the OS as a fresh install from USB, will the CD key be recognized or will I need to do Windows 7 > Windows 10 all over again? I tried a fresh install of Windows 10 previous to installing Windows 7 and the cd key wasn't recognized.
It seems a massive effort to install two operating systems each time I want to format (Something I do every few months to keep the system fresh). Does anybody know if my serial key is updated in the Microsoft database to be valid on a Windows 10 install after the first install or is that unknown as of now? Cheers!
