I am trying to find the windows 10 media overlay popup through enumerating all child windows.

It appears in spy++ as 0x1023c

Its able to find it with FindWindowEx, but not with EnumChildWindows or EnumWindows.

            var targetWindow = FindWindowEx(new IntPtr(0x10010), IntPtr.Zero, "NativeHWNDHost", null);

            EnumChildWindows(new IntPtr(0x10010), (hwnd2, lpvoid) =>
            {
                Console.WriteLine(hwnd2.ToString());

                if (targetWindow == hwnd2)
                {
                    Console.WriteLine("Found it");
                }

                return true;
            }, IntPtr.Zero);

Is there a reason why EnumChildWindows fails to find it? Its not a message only window.
