Windows 2000 Hide Common Dialog Back button
The places bar allows users to navigate via the common dialog directly to the
following locations: History folder, Desktop, My Documents, My Computer, and My
Network Places. When this registry value is enabled, Windows 2000 removes the
back button from the common dialog, preventing the user from browsing to the
previous folder accessed from the dialog.
Value: 1 enable
