Or Is there any command for this process to using at cmd?

Answer 1

You can change the background image of the desktop with SystemParametersInfo().

#include "stdafx.h"
#include <windows.h>

int main() {

    int return_value = SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, L"d:/flower1.jpg", SPIF_UPDATEINIFILE);

    return 0;
}
