{
hwndMain = FindWindow(OBS_WINDOW_CLASS, NULL);
if(hwndMain)
SetForegroundWindow(hwndMain);

CloseHandle(hOBSMutex);
return 0;
}

Because most people would not benefit from having more than one instance of OBS running.

You do NOT need to remove that code, there is functionality in place to open more than one instance of OBS, just make a .bat file and put "obs -multi" in it. (This has nothing to do with development, so I'm moving this post to Questions and Help.)
