Windows 10: 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.

Wipe and install Win 7

Confusing.
I assume you mean "not happy" instead of "beyond happy".

At the very least you'll need:

• A legitimate W7 install disk and Product Key
• KB976932 Service Pack 1
• Driver install files
• KB3020369 Prerequisite for KB3125574
• KB3125574 W7 SP1 Update Rollup (Windows will be updated to April 2016)

Then follow this tutorial:

Once you have successfully installed W7, the updates listed above and the drivers, install a program like Macrium Reflect and create at least 2 Backup System Images (on different external HDDs).

Once you have created the Backup System Images, you can risk downloading the remaining updates for W7.
I only install the Security-Only updates (and some fixes for them):



Note:
You'll also need to apply IE and .NET updates separately.

 

Dual Booting Win 10 and Win 7

So the suggestion is to install the November commercial release of Win 10 Pro to the Win 7 drive and then revert back to Win 7 at the completion of the install?
