Recover my original, valid product key(s)?

Can Microsoft assist me in recovering my original, valid product key(s)? I ran a script that was supposed to reveal the product key, but instead changed the product keys. I was attempting to catalogue the product keys from 3 machines in preparation for Win 11 upgrade. I could post the script if needed. Help!

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

How to recover lost Microsoft Office 2013 Product Key after Windows 10 Reset PC

Although the Windows Lost Product Key question has been asked before, this is slightly different.
I did 'Reset this PC' from Windows 10 Recovery without taking a backup of the system or files. All my files were safe but the Licensed Microsoft Office 2013 was removed. I have unfortunately misplaced the MS Office 2013 Student and Home product box. I have also checked with Windows Helpdesk if any of my emails are associated with the MS Office and the Microsoft Account; sadly, none are.

I read that that the 'Reset' cleans the registry and removes the apps. I am thinking of two ways to try and find the key

1. Use all the Free Key finders around then buy a paid one if they don't work
   
2. Use Recuva or a similar tool to try and recover the deleted old Windows Registry files
   

Has anyone faced a similar issue or can you think of an alternate way to try and get the Key?
