Hi,
Since Windows 11 is newly released, there seems to be no relevant information at the moment.

I don't have Windows 11, but maybe you can try the methods used on Windows 10 :

• By reading values at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
  (MS apps like Winver do that)
• With RtlGetVersion :

    HMODULE hDll = LoadLibrary(TEXT("Ntdll.dll"));
  typedef NTSTATUS(CALLBACK* RTLGETVERSION) (PRTL_OSVERSIONINFOW lpVersionInformation);
  RTLGETVERSION pRtlGetVersion;
  pRtlGetVersion = (RTLGETVERSION)GetProcAddress(hDll, "RtlGetVersion");
  if (pRtlGetVersion)
  {
      RTL_OSVERSIONINFOW ovi = { 0 };
      ovi.dwOSVersionInfoSize = sizeof(ovi);
      NTSTATUS ntStatus = pRtlGetVersion(&ovi);
      if (ntStatus == 0)
      {
          TCHAR wsBuffer[512];
          wsprintf(wsBuffer, TEXT("Major Version : %d - Minor Version : %d - Build Number : %d\r\n"), ovi.dwMajorVersion, ovi.dwMinorVersion, ovi.dwBuildNumber);
          OutputDebugString(wsBuffer);
      }
  }
  

Answer 3

It might be worth giving sysinternal's procmon utility a try, and see e.g. which registry values winver.exe reads.

Answer 4

It would be good to have official guidance from MS on the correct approach.
In the mean time I've found the following works for what I need.

Querying the WMI Win32_OperatingSystem for the "Caption" property which reads "Microsoft Windows 11 Pro" on my test machine.

For a quick test using powershell you can use this command.
get-wmiobject win32_operatingsystem | select Caption

Then combining the above with details like "ReleaseId" or "DisplayVersion" from the registry.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
