<![CDATA[Wrong info about system in What Browser page]]>What Browser ? is a service that identifies and checks if my browser is up to date and other info
I took a screen save of partial finding, the rest of the page has other information that I can't fit all in one screen save![alt text](Screenshot 2023-06-01 201606.png image url)
Opera 99 on Windows 11
is up to date
But its announcing that its
Opera 99 on Windows 10

It looks like you're using version 11, but your User Agent is announcing that you're using version NT 10.0

This conflict might be causing other websites to not detect your web browser properly.
Any way to fix this ?

Thank You for your reply. Apart from low bandwidth
Opera is working fine (waiting for fiber optic cable to come to the neighborhood)

Windows 11 is still NT 10.0 and Chrome sends the same thing in its user-agent string.

Chrome:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36

Opera:

Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.0.0 Safari/537.36 OPR/99.0.0.0

Looking at the sent HTTP headers between Chrome and Opera, I don't see anything different that says Windows 10 specifically. I also don't see anything in Opera's client hints that would cause it to be different than Chrome. Both Opera and Chrome send a platformVersion of 15 for example.

The site's own operating system test at https://www.whatismybrowser.com/detect/what-operating-system-do-i-have says Opera is using Windows 11.

There must be something extra (or a bug) with the site's main test. I didn't see anything in Opera's Javascript navigator object that would cause Opera to be detected as being on Windows 10 either.

I don't see anything in the other tests as https://www.whatismybrowser.com/detect/ either.
