Windows 10: Have a win 10 pro retail, but lost the key, will MS email it to me

I have 4 win 10 pro PC, ok, so this is question about one of them.
I saw this comment here
How to Find Your Original Windows 10 Product Key - TechSpot

So was wondering if I opened up a chat with an agent would they remote into my system (they did that once before to reactivate it) and email me my retail win 10 pro key. I was thinking this board is getting old and someday may just fail.

Plus I see this too from a MS MVP, that even an OEM install can be moved once. Although I dont understand that procedure
exactly about signing into what where and noting what? Just is not clear, can some one explain the procedure better?

Excel will not use Thunderbird to email spreadsheet on Windows 10 Pro

I was trying to keep it simple, she's not the sharpest knife in the drawer but kind natured.
If i could emulate what I can do thenwhen she gets twined up I can talk her step by step.

if we can't sort why Win 10 Excel won't see T-B as the main email client then we'll just have to go with your suggestion.

I should have said Win 10 pro 64 bit?

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?
