用专门的程序，可下载

以下代码可以实现

HWND Wnd;
Wnd = GetDesktopWindow();
Wnd = FindWindowEx(Wnd, 0, "Progman", NULL);
Wnd = FindWindowEx(Wnd, 0, "SHELLDLL_DefView", NULL);
Wnd = FindWindowEx(Wnd, 0, "SysListView32", NULL);
SendMessage(Wnd, 0x1026, 0, 0xffffffff);
SendMessage(Wnd, 0x1024, 0, 0x00ffffff);
InvalidateRect(Wnd, NULL, true);

不过在活动桌面打开时无效
