On Windows, use 'pymolrc', 'pymolrc.py' or 'pymolrc.pym'. For global defaults (all users), you can place a .pymolrc file in C:\Program Files\DeLano Scientific\PyMOL (or C:\Program Files\PyMOL\PyMOL). You can launch PyMOL from the applications menu or from the icon on your desktop (if you placed one there).
