Hi, I am an Independent Advisor.
Let me help you with this issue.
I understand you need to know what the original version of Windows 11 was that came with the machine.
Have you tried checking the Activation Settings to see if Windows 11 Pro is activated?
Go to Settings > System > Activation. Check if Windows is activated and what edition it shows (like Windows 11 Home or Pro). If it's not activated, it could mean you're running a version that doesn’t match your original license.
