Administrator Guide

Steps

1 Log in as WyseAdmin.

If automatic login to a user desktop is enabled, log o from the user desktop and log in as an administrator.

2 To disable the Unied Write Filter, double-click the Dell Wyse WF Disable icon on the desktop.

This icon disables the lter and reboots the system.

3 Congure the Wyse Software thin client as per your requirements.

4 After you congure the Wyse Software thin client, to enable the Unied Write Filter, double-click the Dell Wyse WF Enable icon on

the desktop.

This icon enables the lter and reboots the system. Your congurations on the Wyse Software thin client are now saved, and they

persist after you reboot the thin client.

Next steps

After system start-up, the Unied Write Filter (UWF) starts automatically.

You can add specic les or folders on a protected volume to a le exclusion list to exclude those les and folders from being ltered by

UWF using the Dell Wyse Unied Write Control tool. To access the tool, click the Unied Write Filter icon in the system tray. When a le or

folder is in the exclusion list for a volume, all writes to that le or folder bypass UWF ltering, and are written directly to the protected

volume and persist after the device restarts.

You must log in as an administrator to add or remove le or folder exclusions during run time, and you must restart the device for new

exclusions to take eect.

Setting Write Filter controls

To view and manage UWF control settings, use the Unied Write Filter Control dialog box. To open the dialog box, double-click the UWF

icon in the notication area of the administrator taskbar.

When you congure UWF control settings, some of the elds are unavailable. You can select from the list of available elds during

conguration.

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.

– Overlay used by UWF—Shows the amount of overlay allocated to the Unied Write Filter in Mega bytes (MB) and Percentage. If

Current Status is disabled, overlay allocated to UWF is always zero (0).

– Amount of overlay used for UWF Cache—Shows the amount of overlay allocated to the Unied Write Filter cache for the current

session in Megabytes (MB).

– Warning #1 (%)—Shows the UWF cache percentage value at which a Low Memory warning message is displayed to the user for

the current session.

• UWF Cache settings

– Amount of overlay to be used for UWF Cache—Shows the amount of overlay that is to be used as the Unied Write Filter cache

for the next session in MB. This value should be in the range of 256 MB to 2048 MB. There is an extra check to ensure that this

value does not exceed 50% of Total Available overlay.
