    Will my Win 10 install now still be licensed after r revert to W7


    A long while back, when Win 10 first was released and the GWX nagware was prevalent, I was running
    Win 7 Pro 64 and I decided to try the new Win 10 to see how I liked it. So I got the free upgrade version
    to Win 10 Pro and installed it on my PC and ran it for several days. As I recall, due to some incompatibility
    issues, I had to remove Win 10 after I could not resolve the problems, and I reverted back to my Win 7 Pro 64 version.

    Now here is my question: I want to try Win 10 again. Do I have to purchase the upgrade even though I had
    the free version before? Or will my earlier install still enable my upgrade this time to register and activate at no charge?
    Will I be able to use the digital license and/or key generated at that earlier time, or am I out of luck, presuming Windows
    still remembers my previous Win 10 install? I am still doing this on the same machine as before.

    If I still get it for free, how should I install it, do I need the Media (or whatever) tool? Or can I just directly download it and install it?
    I would like to save it to a DVD as an iso file, though, I may want to do that instead of directly from the download. Will I still
    be able to revert to my Win 7 as before if I so desire?

    Thanks for whatever you can tell me about this.

    "Or will my earlier install still enable my upgrade this time to register and activate at no charge?"
    --- Does this mean your earlier install didn't activate?

    If you use the MCT/Media Creation Tool you can download the .iso to later create the bootable DVD or you can use an 8GB USB Thumb drive to create a bootable device to install from.
    Download Windows 10

    If Win10 was previously activated there should be an entry in Microsoft's Activation database about the computer and again activate the installation.

    Does it (W10 update) show in windows update? You could try that first, although depending on your internet connection just downloading it to begin with as @Berton post's could be your best option. Even if the initial install fails, you have an iso on hand and won't need to download it again.

    I agree that if your first upgrade to W10 was activated you should be ok.

    Second Win 10 install free?


    Thanks for the replies. Yes, the first time I installed Win 10, I cativated it, so I hope it is still free.

    I qwill give it a try, make it an ISO, worst that can happen is I once again revert back to Win 7 Pro 64
    which I love anyway.

    Thanks

    Reverting to or installing another OS does not invalidate the Digital License it got for Windows 10. I have several PC's here with multiple DL's for just about every edition or Windows 10. I do clean installs sometimes Pro, sometimes Enterprise. They activate just fine with the DL stored on the activation server without ever entering a product code. I even went back to Windows 8 on one PC, then back to Windows 10 with no issues. I've installed Linux on my spare desktop a time or two and went back to Windows 10, same deal, no having to enter a product code to activate. As long as you install the same edition you got via the free upgrade, 10 Pro in your case, you should be fine.

    Instead of trusting Windows to revert back to the old OS should something go wrong, I would make a system image using a program such as Macrium Reflect Free just to be sure I could back.

    Revert to previous Win version


    Indeed, I do that, via my Acronis True Image Backup program, for just about everything that is similar to this situation.
    Of course, the problem is whethewr you can trust the backup software to do its jjob when the time comes. I haveonly had to
    restore an image backup one time in all my years so far; It went well, but it is a time when you sweat blood waiting for the
    restore operation to complete, praying it worked. :=)

    Nevertheless, the last time when I tried Win 10, I was able to revert very easily back to Win 7, it worked flawlessly. So I am not
    worried, one way or another, I will be safe I think. If I do have a problem with activating for free, I will juts go back to Win 7 which
    I am still very satisfied with, best and most trouble-free version MS ever had IMO. In fact, the only reason I am really trying the
    Win 19 upgrade again is in hopes that it has significantly improved the ease of access functions since Win 7; I really need that help
    when I use my computer these days.

    My biggest worry right now is wondering whether my memory is really good, did I really activate Win 10 when I did the earlier
    trial install of it. I am pretty sure I did because I do know I ran it for about a week before I went back to Win 7, mainly because
    of some compatibility issues with some WinXP stuff I still use in Win 7, but also because even if Win 10 worked great I would
    not have permanently switched to it at that time. I always wait for at least until the first update patch is released before I really trust
    any MS software enough to be usable and reliable.

    Thanks

    This is a case where a spare hard drive is useful. You can swap out the current one with your good install of Win7 on it, replace it with a spare one and test the restore to that - all the time safe in the knowledge that the original drive can be put back in when you're done.

    If you have put a spare drive in, then you could try a clean install of the same edition of 10 as you had before (Home or Pro, if you have a digital licence it is only valid for the one you got in the upgrade). When asked for a key click 'I don't have one'. If you have a digital licence it will activate automatically as soon as it can contact the activation servers.
