Windows 10: Re-enable windows 10 after a windows 7 downgrade

    Re-enable windows 10 after a windows 7 downgrade

    Due to a few driver issues i tried a downgrade to win7. I loaded a win7 install disk and did a custom install. Booted ok, but i have decided it's not worth the effort to re-install all my old programs, so i want to revert back to windows 10.
    The win7 install placed the Win10 files in the standard windows.old file.
    MS has this article for reinstalling the windows.old:

    Wondering if that's all there is to it (although step5 of restoring the MBR is not specific for windows 10)
    Has anyone else done this, or have any suggestions?

    I would download Win 10 ISO from MS, if you didn't make a copy of it and install clean version.
    Activation shouldn't be a problem, since you already activated Windows 10 on this machine.

    thanks for the idea, but that would also require a re-install of all software, which i was trying to avoid.

    That's true.
    I didn't go that way yet (usually just from 10 back to 7), so hopefully somebody who did will confirm this is correct path.

    Good luck!

    Edit: And why don't you make usual upgrade?

    Well, i renamed the windows.old files, rebooted, and...
    Win10 mostly came up, but the start button no longer works, and outlook also does not work, otherwise the other 75% works. To bad MS doesn't support this reversion.
