I'll be building a new computer in the next few days. Sifting through a few threads, I can't tell whether or not I'd be able to install Windows 8 on it if I were to: Download Upgrade Assistant on this computer (legitimate Windows 7, but from 2010) Buy Windows 8 Upgrade Pro using a promo key (that I already got from a fake request) (so the $15 one) Anyone have a definite answer? And if so, how would I go about doing it? All these threads confuse me on either steps or whether I can do it in the first place.
