The Dell Wyse Unied Write Filter Control dialog box includes the following:
• UWF status
• Current Status—Shows the status of the Unied Write Filter. The status may either be Enabled or Disabled.
• Boot Command—Shows the status of the Boot Command. UWF_ENABLE means that the UWF is enabled for the next session;
and UWF_DISABLE means that the UWF is disabled for the next session.
• RAM used by UWF—Shows the amount of RAM allocated to the Unied Write Filter in Mega bytes (MB) and Percentage. If
Current Status is disabled, RAM allocated to UWF is always zero (0).
