Windows 10: How to recover original laptop windows 11 product key

I recently bought a DELL laptop with built-in windows 11, and I tried to change the laptop's license key duo lack of language support. But it didn't work and I'm stuck with no product key. How can I revert it to the original one? I've tried the command but it didn't give me the laptop's original product key

Hello,

I have just bought a new laptop, and it has its own product key for windows 11. However, I upgraded the windows version to windows 11 pro. Now, the product key is no longer working, and I want to recover the original windows 11 version where the product key is licensed.

Thank you,

 

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!
