Windows 10????

[mcc1961]

I started out with Windows 7 and free upgraded to 10.After I put 10 on my computer I downloaded 10 to a USB drive from the microsoft website and was wondering on down the road after the free promo is up will I be able to use the USB drive to reinstall windows 10,also what key code will I use with 10 ?Will I use the Windows 7 key or will I get a new one for 10?

Did you create the microsoft account when you installed 10? If so, then once you reinstall 10 fresh and sign into your account, it automatically activates.
