Windows 10: Windows 11 Pro Education N Activation Key

I purchased a used laptop that has Windows 11 Pro Education N loaded but do not have an activation code. Can I purchase one and if so what would be my most economical option?

Full format, reinstalled Windows 11 Education N (upgraded from Win10 Edu N). Product key was tied to my personal account. Can't login, can't locate key

tl;dr: reinstalled a win11 edu n pc, thought key was already saved on my microsoft account. Tried signing in and couldn't, now stuck without a key that I should still have the rights to. How do I claim it back?

Hiya Microsoft community!

I've recently fully formated and reinstalled my PC, which was running Windows 11 Education N that I upgraded from Windows 10 Education N. Before I formated, I tried to check my product key but the settings page said that it was tied to my personal Microsoft account and I figured that I am all clear to reinstall. Just a while ago, the reinstallation went fine and I was prompted to install the version I would like to have installed, so I chose Windows 11 Education N, since that's what I had.

Unfortunately, the Windows 11 Education setup now requires a .edu email domain, and having graduated a while ago from the institute that I was studying at a long while ago, that email has been deleted and I no longer have access to it, or the azure site that gave me access to the key. So I tried to go along the setup process and tried installing Windows 11 Pro N (since I've heard that Education N and Pro N are essentially feature equal to each other) and still, the product key that was tied to my personal account was not automatically detected for the activation. I've also tried to check my Microsoft page for my old PC and see if it was listed there, but found that the device is no longer listed and I cannot find the product key at all.

How can I find and use the product key that I thought I should still have?

Activating Windows 10 Education N from Windows 10 Education

Hi, so it is pretty simple. I installed Windows 10 Education N without activation key on my computer. I bought a product key but for Windows 10 Eduction (so not the 'N' version). Is there a way to use the key without having to reinstall Windows 10 Education
from scratch ?
