This should be reported upstream to libuv, which is the project that provides node with that information.

On a related note, it seems the current consensus is that if dwMajorVersion is 10, then you need to check if dwBuildNumber >= 22000 is true. If it is, then it's Windows 11 and not 10.

Yes, and I know C++. GIve me the related files and functions, and I will fix them.

libuv picks the version details from windows registry Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion. The productName registry entry on windows 11 contains windows 10 .
We will either have to get this fixed from windows side or change the libuv implementation to accommodate the required changes

Also, windows official documentations doesn't yet address windows 11 in the version detection APIs.

Wondering about the API or the implementation details of Winodws About . About displays appropriate information.
Any resources or pointers would be helpful.

Maybe 'Windows About'.

From another web:

// CurrentMajorVersionNumber present in registry starting with Windows 10
// If CurrentMajorVersionNumber not present in registry then use CurrentVersion
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\CurrentMajorVersionNumber
// CurrentMinorVersionNumber present in registry starting with Windows 10
// If CurrentMinorVersionNumber not present in registry then use CurrentVersion
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\CurrentMinorVersionNumber
