Windows 10: Accidentally Deinstalled Product Key: How to Recover?

I accidentally used the slmgr -upk command in cmd without knowing what it does. I know it wasn't smart at all to do it, but that's how it ended up. Now I have removed my Windows 10 Pro Product Key and I'm unsure of how to recover it. It was not preinstalled, I bought a new version to use it, and have been using it for probably over 5 years now. I'm not sure if I still have the product key anywhere else, I'd just like to know if there's a digital variant to recover it.When I use any command to reinstall or read, like slmgr -dti, -ato or -dlv I can not read it or reinstall it. I've also been usi

Incorrect. The OEM Windows 10 Pro key is embedded in the bios. There was no need to buy anything....

If a product key was sent out previously to my email, however it has been deleted what are the steps to recover your product key ID?

 

Recover product key

How can I recover a lost product key for a windows server 2016 license? I have the proof of purchase that contains the COA (certificate of authenticity) bar code, I would imagine that based on this I would be able to either get the corresponding product
key or a replacement one. The product key was not used on the server as it was never taken out of the envelope that contained it so I can't recover it from the actual server.
