I try CreateWindowEx with WS_EX_NOREDIRECTIONBITMAP
But get GetLastError() = 87 (ERROR_INVALID_PARAMETER)

WS_EX_NOREDIRECTIONBITMAP = 0x00200000

Code:

    wc.cbSize        = sizeof(WNDCLASSEX);
    wc.style         = CS_HREDRAW | CS_VREDRAW ;
    wc.lpfnWndProc   = WndProc;
    wc.cbClsExtra    = 0;
    wc.cbWndExtra    = 0;
    wc.hInstance     = GetModuleHandle(NULL);
    wc.hIcon         = LoadIcon(NULL, IDI_APPLICATION);
    wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
    wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
    wc.lpszMenuName  = NULL;
    wc.lpszClassName = g_szClassName;
    wc.hIconSm       = LoadIcon(NULL, IDI_APPLICATION);

    if(!RegisterClassEx(&wc))
    {
        MessageBox(NULL, "Window Registration Failed!", "Error!",
            MB_ICONEXCLAMATION | MB_OK);
        return 0;
    }
HWND const window = CreateWindowEx(WS_EX_NOREDIRECTIONBITMAP,
                                   wc.lpszClassName, "Sample",
                                   WS_OVERLAPPEDWINDOW | WS_VISIBLE,
                                   CW_USEDEFAULT, CW_USEDEFAULT,
                                   CW_USEDEFAULT, CW_USEDEFAULT,
                                   nullptr, nullptr, module, nullptr);

But without WS_EX_NOREDIRECTIONBITMAP CreateWindowEx work fine and not get any errors.
And i see on monitor created window.

I don't know for certain, but support for that flag might have started with Windows 8?

Strange msdn write WS_EX_NOREDIRECTIONBITMAP support on Windows 2000

From the MS Windows 10 SDK winuser.h

Code:

#if(WINVER >= 0x0602)
#define WS_EX_NOREDIRECTIONBITMAP 0x00200000L
#endif /* WINVER >= 0x0602 */

0x0602 is _WIN32_WINNT_WIN8

hey, you can always use a transparent bitmap to load (custom stuff and drawing), that would be nearly same effect.
just dont lose hope.
