If you mean to prevent write access to the flash drives, yes. Under SS, there is a checkmark to "Prevent write Access to USB drives" which you can see here http://windowsreference.com/images/steadystate/windows_steadsystate_restrict.PNG PhilipJealousy is not proof of love, nor proof of emotional immaturity
