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?

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.

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.

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

Thanks for the info. I will try it maybe next week. Let you know if I have any problems.

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.

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
