I don't know why your code does not work, but if you change RegisterClassEx to RegisterClass then it works for some reason. Perhaps someone else knows exactly why.

#include <windows.h>
LRESULT CALLBACK WindowFunc(HWND,UINT,WPARAM,LPARAM);
char szWinName[] = "MyWin";
int WINAPI WinMain(HINSTANCE hThisInstance,HINSTANCE hPrevInst,LPSTR
                   lpszArgs, int nWinMode)
{
    HWND hWnd;
    MSG msg;
    WNDCLASS wcl;

    
    wcl.hInstance = hThisInstance;
    wcl.lpszClassName = szWinName;
    wcl.lpfnWndProc = WindowFunc;
    wcl.style = CS_HREDRAW | CS_VREDRAW;

    wcl.hIcon = LoadIcon(NULL,IDI_APPLICATION);
    wcl.hCursor = LoadCursor(NULL,IDC_ARROW);

    wcl.lpszMenuName = NULL;
    wcl.cbClsExtra = 0;
    wcl.cbWndExtra = 0;
     
    wcl.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    if(!RegisterClass(&wcl)) return 0;

    hWnd = CreateWindow(
        szWinName,
        "My First Window",
        WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT,
        CW_USEDEFAULT,
        CW_USEDEFAULT,
        CW_USEDEFAULT,
        NULL,
        NULL,
        hThisInstance,
        NULL
    );

    ShowWindow(hWnd,nWinMode);
    UpdateWindow(hWnd);

    while(GetMessage(&msg,NULL,0,0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return msg.wParam;
}
LRESULT CALLBACK WindowFunc(HWND hWnd,UINT message,WPARAM wParam,LPARAM lParam)
{
    switch(message) {
        case WM_DESTROY:
            PostQuitMessage(0);
            break;
        default:
            return DefWindowProc(hWnd,message,wParam,lParam);
    }
    return 0;
}

You must set the hIconSm member of WNDCLASSEX
