The options that you can use with Explorer.exe are /n, /e, /root (plus an object), and /select (plus an object).

Option            Function
  ----------------------------------------------------------------------  
  /n                Opens a new single-pane window for the default
                    selection. This is usually the root of the drive that
                    Windows is installed on. If the window is already
                    open, a duplicate opens.

  /e                Opens Windows Explorer in its default view.

  /root,<object>    Opens a window view of the specified object.

  /select,<object>  Opens a window view with the specified folder, file,
                    or program selected.
