Windows 10: Clean-install Windows 7 after the Win10 revert option has expired?

Hi.. I see there's a fairly recent thread called "Downgrading to Windows 7" but that's not applicable to me. I haven't got the "go back to an earlier build" recovery option. So, here's my situation:

HDD 0 is my surfing C drive, and has Win10 - that Win10 being a July 'upgrade' of Win7.
HDD 1 is a non-OS drive. I want to use my Win7 disk to create a new OS from scratch on this HDD 1.
HDD 2 has an earlier Win7 with no internet access, and I want that left untouched. So let's ignore HDD 2.

Now, I gather that Win10 has might have 'locked on to' my MS licence, and may have revoked use of the product key for Win7. So my questions are these:

1: If I go to all the bother of installing Win7 on HDD 1, will the product key be accepted?

2: If the answer to 1 is 'no' then what if I totally wipe Win10 from HDD 0, and then try installing Win7 again? Might I be left in a situation where I can't have Win7 on my PC, and have lost my rights to Win10 as well?

:)

 

Windows 10 Flashing Screen, no Sound & Numerous Other Issues

Provided you have not run a disk cleanup and removed your Windows 7 installation files, you are supposed to be able to revert to Windows 7. Unfortunately I don't have that option, as I have a 128GB SSD, and was getting available space warnings after the
Win10 installation, and I had disk clean up remove the Windows 7 files to make space.

 

Downgrade win10 to win7

So basicly if I were to now install the latest version of win10 instead of insider version I still couldnt revert back to win7 because the revert option would be the previous version of win10 I had.

I will wait a bit longer,but if there is no solution I will have to backup my files and do a clean install of win7.

I honestly didnt have this much problems with any os so far.(xp & 7)

 

The Windows 10 upgrade did nothing to your Windows 7 product key, it remains just as valid to use in any legal installation as it always was. HOWEVER it violates the End Users License Agreement to have the Windows 7 and Windows 10 upgrade resulting from that Windows 7 license installed on the same computer at the same time. Thus it also violates this forum's rules to discuss how to do it. You have 1 license/product key for Windows - that means only one installation of Windows is legally allowed from that license/product key, Windows 10 or Windows 7, not both; even though only your honesty is preventing you from using the same license for both the Windows 10 and Windows 7.

If you choose to purchase a second license for Windows, then you can see here for more information:

Ooops, sorry about forum violations. Minefield alert... guess I'm one of the folks who didn't read the EULA properly!

I think I'm safe in asking, though: if someone were minded to ditch Win10, and just have Win7 on their PC... thus simply rolling the clock back to how things were a few months ago... then presumably that's within both the letter and the spirit of the law?

(And here I mean both MS EULA law and also 10Forum regulations.)

 

Yes, you can ditch (remove) 10 and go back to 7. You'll need install media and a valid product code. If you have factory recovery media you can use that to restore the original 7 OEM install. If not use the key on the COA sticker.
