Windows 10: I am building a pc, and bought windows 11 pro but didnt look at the product key, I lost...

When building my computer, i got everything working and bought an official copy of windows 11 Pro, but due to some issues that are taken care of, i cannot get the windows key back, and is lost on that OS drive i had it for only a couple of hours before it formatted itself due to previously mentioned problems. Is there a way i can get that key back or refund the transaction to get a new one because i still have the old pc and am giving it to a family member so i dont want to use that key.

Windows 11 home to Windows 11 pro upgrade by product key - not active

HI,

I bought a product key for windows 11 pro, I did install it however i get error code an not able to activate -> 0x80072EE7.

Is there a way to resolve the issue? Tried to do the phone activation but it doesnt help. Windows suggest installing windows 11 home again (which I dont want since I bought windows 11 pro).
