@sv-calin when you expect it to be Windows 11. What is the user agent string of your browser? Both Chrome and Firefox have started to freeze parts of their user agent strings.
For example, if you go https://echo.opera.com with Windows 11, what is the UA string for Chrome and Firefox?
from echo.opera.com

Tested on: Windows 11
So as you can see. This is normal. We can't fix this. :) It's on purpose. Browsers are starting to freeze the information in the UA string to avoid fingerprinting (and sniffing). :)
Some of these data maybe accessible through UA client hints but only in Chrome for now. @miketaylr might be able to confirm. I don't know if @ksy36 has enough time to parse Client Hints if the information is there

Yeah, you can get the correct Windows version via UACH. See https://learn.microsoft.com/en-us/microsoft-edge/web-platform/how-to-detect-win11
