My Windows 11 Key - Why do I get two different keys shown if I search using different methods?

[Mikelmouse]

Why do I get two different keys shown if I search using "BackupProductKeyDefault" in the Registry and "wmic path SoftwareLicensingService get OA3xOriginalProductKey" in Terminal (Admin)?



The machine is an Acer laptop purchased new, with Windows 11 pre-installed, and not re-installed since. The key reported by cmd line, Belarc Advisor and the line "LastBiosKey" in the registry is the same key, but that using "BackupProductKeyDefault" is different?



I wanted to make a back-up of my key.



Is there a better method?
