The only thing that the patched version really offers in this regards is 
the possibility to actually avoid sending lwindow etc to the system:

LRESULT
CALLBACK
LowLevelKeyboardProc(INT nCode, WPARAM wParam, LPARAM lParam)
{
...
             case VK_LWIN:
               {
                 bHandle = NILP(Vw32_pass_lwindow_to_system);
                 break;
               }
             case VK_RWIN:
               {
                 bHandle = NILP(Vw32_pass_rwindow_to_system);
                 break;
               }
             case VK_CAPITAL:
               {
                 bHandle = NILP(Vw32_enable_caps_lock);
                 break;
               }
             case VK_NUMLOCK:
               {
                 bHandle = NILP(Vw32_enable_num_lock);
                 break;
               }
             case VK_MENU:
             case VK_LMENU:
             case VK_RMENU:
               {
                 bHandle = NILP(Vw32_pass_alt_to_system);
                 break;
               }
       if (bHandle) {
         // Just to be sure check we are in the right thread
         if (GetCurrentThreadId() == dwWindowsThreadId) {
           // Do we have keyboard focus?
           HWND hwnd = GetFocus();
           if (0 != hwnd) {
             SendMessage (hwnd, msg, wParamMsg, lParamMsg);
             return TRUE;
           }
         }
       }
     }
   HHOOK hhook; return CallNextHookEx(hhook, nCode, wParam, lParam);
}


And then it also offers easy way to set things up up, see w32-meta.el 
that comes with the patched Emacs+EmacsW32.
