Firmware updater brings 2.0 units to the latest firmware. This update is on-demand if a user attempts to use functionality which requires a firmware update such as click to lock.
Click to lock allows users to manually lock their workstation using the GateKeeper 2.0 button. This feature may require a firmware update for older 2.0 units.
The CREDUI usage scenario allows GateKeepers to be used with windows credential input dialogs. These are used to run programs under a user account, edit remote desktop settings, and add network drive mappings.
