Upgrade Win-11 Home to Pro, now what?

[king1]

My upgrade to Win-11 Pro has finally been completed.
I've had no response from MS in answer to my questions, but tried again last night and the install began without me seeing a Product Key to install.
Where may I find this new Product Key?
Thank you all for your interest.

I would have thought it would have been in an email sent to you when you bought it, but you should be able to extract it using Produkey

You might need to disable your antivirus software to run this as it is considered by some to be malicious...
