    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.

    From my experiences, if you use the Upgrade Product Key on an clean install, you'll need to have and old Windows OS running on your machine.

    But: you could use the RTM ISO (download from here: No. 1 or 3 from the first post) for to do a clean install without problems. Some users reporting that they later on need an Fix which I wasn't need ever till now with a few hundreds installations.

    So, the steps as follow:
    • buy an upgrade key
    • download an RTM ISO 32bit or 64bit
    • Create an bootable DVD or USB Drive
    • start computer and boot from installation media
    • follow screen instructions
    • at the screen Upgrade or Custom Installation, chose later, let Windows create required Partitions and let install run till finish.
    • within install key in your new Upgrade Key when asked.
    Windows will automatically activated. Those activation will be checked on every boot.

    Any more questions, please ask.
