Windows 10: Having trouble finding Window 10 Pro Product Key from an Order Placed at Microsoft Store

Hello,Back in 2017, I purchased an Window 10 Pro directly through Microsoft.com see order history below.For a while, I don't have any Window PC and the last machine using that license was wiped clean and traded in. Now I am trying to use this vacant license in a newly assembled desktop and will need product key. However, I couldn't find it anywhere. I've read a few questions, most of which directed us to find it from confirmation email or order history, but I didn't find any product key from either of the places. I wonder if there is a way for me to find out what my product key is? I haven't

Product Key not on Order Page

I ordered an upgrade from Windows 10 Home to Pro recently. The upgrade occurred automagically, but I now have no product key. I spent some time and went to my account, finding the order and selecting it. Microsoft support under "Product Key" says to

Go to Order history, find ,
and then select Product key/Install

I looked at the order summary and detail on Order History. There was no Product Key. Much appreciate some help.

(SOLVED) Cannot Access Windows 10 Pro Product Key

I have recently purchased an upgrade to Windows 10 Pro from Windows 10 Home so that I can use remote desktop features. I made the purchase on my desktop PC through the Microsoft Store, which led directly to installation.

When I attempt to install the upgrade on my laptop, the Microsoft Store asks me to purchase another Pro upgrade or enter an existing product key. The suggested location to find this key is in my Microsoft Account Order History. My order of Windows 10 Pro
appears here but does not display any product key. The order contains one clickable link - Windows 10 Pro on the order leads to a broken link (404). The email receipt for the order contains all the same.

What am I missing here? How may I work around this? Very disappointed having just purchased a product I cannot fully use.

SOLUTION: I have identified that only the server PC requires Windows 10 Pro; A PC running Windows 10 Home may remotely access a PC as long as the remote unit has Windows 10 Pro or better.
