Use double-panel Explorer when opening network drives (Windows 98/Me/2000/XP)

By default when opening network drives (UNC) the Explorer window opens with a single-pane which does not show the Folders section on the left-hand side. This tweak changes the default behavior to open network drives with a double-pane view.
1.Open your registry and find or create the key below.
2.Create a new String value, or modify the existing value, called "(Default)" and set it according to the value data below.
Exit your registry; you may need to restart or log out of Windows for the change to take effect.

Registry Settings
System Key : [HKEY_CLASSES_ROOT\Folder\shell\open \ddeexec]
Value Name : (Default)
Data Type : REG_SZ (String Value)
Value Data : ([ViewFolder("%l", %I, %S)] = default, [ExploreFolder("%l", %I, %S)] = double-pane view)
