How to check my windows 11 license key original or duplicate?

I bought a brand new laptop and this message appeared when I was digging to know if the windows was activated. It is activated but I think it is a duplicate.

Perform three-step verification:
1️⃣ Open CMD and enter: slmgr /dli Check "Description" and if it shows OEM, it is a genuine pre-installed version
2️⃣ Check whether the serial number of the machine matches the device ID bound to the Microsoft account (Settings>System>Activation)
3️⃣ If it shows a retail version key, immediately find a merchant to replace it with a new machine - your motherboard may have been applied with a second-hand key
(Appendix: Genuine laptop activation should show "Windows has been activated with a digital license" with an OEM channel logo)
