Reverted from 10 to 8.1 a few months ago, revalidate for Clean install?

Hi all,

I did an upgrade from 8.1 to 10 a few months ago and had issues so reverted back to 8.1.

Now I want to clean install windows 10 to likely avoid those issues.

I've learned from clean install tutorials that you should first upgrade to 10 so the machine recognizes that the computer is authorized to use Windows 10, and THEN do the clean install (i.e. going straight to the clean install may result in Windows 10 not activating).

Since I did upgrade to windows 10 at one point, I can now go straight from 8.1 to 10 via a clean install and still have 10 activated, right? Thanks.

Thanks but that does not fully answer my question. My question is basically: Does a time gap of a few months between reversion to 8.1 from 10 (I did NOT verify that it said windows 10 activated but used Windows 10 for weeks) matter regarding whether Microsoft's servers say my machine is authorized for use with 10?

If it was activated on 10, your license from 8 isn't valid and your new key for 10 is your hardware profile.
