Laptop/portable computer users ! Undock without logon

I read about this over the Internet. This would allow you to undock without logging on to Window XP.To do this, open registry by going to START-RUN and entering regedit. Navigate to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System] . In this look for value of "UndockWithoutLogon". Setting its value to 1 to enable it or 0 to disable it.
