Windows 10: Will Win8.1 Pro activation code work on Win10 Pro clean install?

    Will Win8.1 Pro activation code work on Win10 Pro clean install?


    Hello,
    Like the title says, will it be possible?
    If yes, it makes sense.
    If no, how users who upgrade from 8.1 supposed to clean install Win10 down the line in the future?

    Will we (win 8.1, 8 and 7 owners) be given new activation codes?

    Thanks

    No.. you can't use a WIn8.1 key to activate a copy of WIn10. And MS has not really said how the ISO will be distributed. I think and so do some others that when we do get access to it we will have a new key for WIn10.

    From what I've read on this forum and others along with E-Mail I've received the free Win10 Upgrade will be offered only for Win7 w/SP1 and Win8.1, not for Win8.0 or Win7 with no SP.

    The 7 or 8.1 key will be used to qualify the upgrade though, right, either embedded or entered via keyboard.

    If I allow the upgrade from a genuine Win7 activated with a product key that I own to Win10, am I provided with a genuine product key for Win10? I ask this as there will be a time in the future when I'll have to reformat & reinstall Win10.

    No, that's not true. Only Windows 7 SP1 and Windows 8.1 S14 will *automatically* be upgraded via Windows Update. Windows 7 RTM, Windows 8, and Windows 8.1 (pre-S14) will have to use an ISO to upgrade, but the free upgrade is still valid.

    No, it doesn't look like they will be giving out new keys, although you should be able to get your key by using a key discovery application. Still, that's generally not necessary as Windows will know that you have already upgraded and have a valid license. The clean re-install will simply not ask for a key and automatically activate. Don't ask how it knows, it may have something to do with what's called the "extended PID", but we don't know. Regardless, Windows will know that you have already upgraded and automatically activate.
