Windows 10: Upgrade of non-Pro 8.1 from 10 Pro ISO activated on the same hw

    Upgrade of non-Pro 8.1 from 10 Pro ISO activated on the same hw


    I have this riddle to solve: I bought my computer with 7 Pro pre-installed and OEM-activated. I wiped that and clean-installed 8.1 I bought on the side—not Pro, as I wrongly assumed I wouldn’t really need it. Now, however, I’d like to get to 10 Pro on my machine, which is still validly licensed to run Win 7 Pro, so I figured I would re-install 7 Pro on some other disk and upgrade that to Win 10 Pro and have it activate (= register with Microsoft for my machine).

    Then I’d go back to my non-Pro 8.1 disk and try to install 10 Pro over it, using DVD from ISO, choosing upgrade. Any educated guess what this would do and whether these steps could possibly go through as intended?

    If you install your 7 pro and is activated, then upgrade to 10 pro and are activated again. after that activation you can change your hard drive and use a windows 10 pro disk or a 10 pro usb flash stick and install windows 10 pro . So that 8 home you have will be wipe off and only left with 10 pro, is that what you want ?

    Nope, I want to upgrade that non-Pro 8.1 into 10 Pro.
    I mean, if you install from a DVD, there is still a generic upgrade option in the process—as the first option, whereas “advanced”, clean installation is the second option.
    I want to use a Windows 10 Pro DVD—on a computer hw on which an upgrade to W10Pro would have already succeeded—to then upgrade a non-Pro 8.1 (the one I’m really using now), so that I don’t have to re-install everything.
    I understand that—as Plan B—there would be some user-state migration tool (or what’s its name), but I’d obviously prefer an in-place upgrade.

    I believe I get it now . You want to activate a pc with windows 10 pro and once its been activated go back with a different hard drive which has windows 8 home and take a windows 10 pro disk and upgrade the 8 home to 10 pro from the 10 pro disk, yes ?

    MJS,

    Windows 7 Starter, Windows 7 Home Basic and Windows 7 Home Premium can only be updated to Windows 10 Home. If you have a 32-bit version of Windows 7 it can only be updated to a 32-bit version, and a 64-bit version of Windows 7 can only be updated to a 64-bit version.

    Windows 7 Professional and Windows 7 Ultimate can only be updated to Windows 10 Professional.

    Windows 8.1 can only be updated to Windows 10 Home.

    Windows 8.1 Pro and Windows 8.1 Pro for Students can only be updated to Windows 10 Pro.

    @MISTERSTAN48 yes, I know that and thank you for posting that but what I believe MJS wants to perform is totally different and interesting to know the answer . You see Misterstan48 once anyone upgrade to windows 10 and is activated Microsoft record your computer id number . Afterwards one can perform clean installation or what ever and Microsoft will activate what it has recorded with that system . So what MJS is going to do is activate windows 10 pro and swap the hard drive which he can and try to upgrade his windows 8 home edition with a windows 10 pro disk into the system that has already been recorded with windows 10 pro . That is if I understood him correctly ... Hey Brink if by chance your reading this . What do you think can he do such ?

    Yes, exactly. That’s what I’m going to try as my seemingly best available option.

    you have to do two upgrades (been there and done that)

    If you want to upgrade 8.1 Home to Windows 10 Pro, not going to happen..

    if you want to upgrade 8.1 Home to Windows 10 Home, that works..

    Now you can upgrade Windows 10 Home to Windows 10 Pro
    (thus recalling the prior Windows 10 Pro activation) that works..

    Hmm. Interesting. Thanks!

    So, basically, you’re saying that Pro DVD is going to refuse to upgrade an 8.1 Home installation?
    And how do you do the other step, given that the “upgradees” are no longer getting any product keys?
    Do you install from Pro DVD over the Windows 10 Home installation, then?

    No , I believe he's saying what you want to do
