Windows 10: Reactivating W10 after hardware change

Have been over various articles for the last ~3 hours, among other things, little of which is helpful, most of which results in going in circles looking for something you've missed.
As a result, I'm likely more than a little aggravated and passive-aggressive. Iwould apologise in advance, but I'd be lying, and feel it's quite warranted at this point.



Replaced hardware recently, moved HDD's and SSD's over I'm aware of the potential instability/driver issues.
Have previously changed hardware at least once before. Was originally on a W7 Pro Retail license, 'upgraded' to W10 Pro, obviously at some point, first hardware change occurred some time after that, and I'd noticed the "activated with a digital license" change in licensing method.

Now, with this recent hardware change, something else has clearly changed, as now it's failed to activate.

Which would imply:


Hmm.
Troubleshooting the activation issue, and selecting "I've changed hardware on this device recently":




Since, I'm rather privacy-conscious, I've never linked my MS account to it until recently and the fact that it shows my PC's HDD/SSD with the "bitlocker data protection" section, including the drive names and free/used size, is precisely the kind of reason behind that decision, but that's a whole 'nother argument.

Found my way to using Command Prompt/Powershell and 'slmgr /dli':


Do note the 'RETAIL channel'.


That 'notification reason', being:



Which implies I need to go find wherever the original W7 disc and key has been buried in the last few years thankfully I made sure never to dump it entirely, but god only knowswhere it is.


So, am I SoL unless I go dig that up, or buy another W10 Pro key?

If you're averse to phone calls for any reason, or aren't finding relevant articles/answers/forum posts, what the hell else are you gunna do?
Don't see why you've no option for either email-response, and/or ticketing system to handle aforementioned email responses.

windows 10 reactivation after hardware change

I just changed motherboards, and When I follow the the steps listed in the "reactivate windows 10 after hardware change" support page, it gives me the message "unable to activate windows" message after I sign in and identify my device,
with no error code, just a subheader that says "can't activate windows 10 on this device, try again later."

 

Windows 10 won't reactivate after a hardware change

I changed a lot of the hardware on my device recently, however I followed the steps on the Microsoft support page to get my computer ready for the hardware change so that I could reactivate Windows 10 after I changed the hardware. However, now it won't reactivate,
and has the error code 0xC004F025, and when I try to troubleshoot it says "We can't reactivate Windows on this device. Try again later."

My Windows 10 was a free upgrade from Windows 7.
