Dell Latitude 5280 Microsoft Windows 10 IoT Enterprise for Wyse Thin Clients A - Page 29

CAUTION: Please follow proper write filter and Windows Page File usage instructions at all times. Such instructions include making sure that the write filter is enabled during regular use and is disabled only temporarily by an administrator when required for image upgrades, applying security patches, registry changes and application installation. The write filter should be re-enabled as soon as such tasks are completed. Such instructions further include never enabling the Windows Page File feature during regular use of the thin client. Any operation of a Dell Wyse Windows Embedded Thin Client with the write filter turned off during regular use and/or with the Windows Page file enabled will prematurely wear out your Flash/SSD storage, decrease performance and decrease the lifespan of the product. Dell is not responsible for, and will not, warrant, support, repair or replace any thin client device or component that fails to operate properly due to a failure to follow these instructions. Using Unified Write Filter To configure thin client devices using UWF, do the following: 1 Log in as an administrator. If automatic login to a user desktop is enabled, log off from the user desktop and log in as an administrator. 2 To disable the Unified Write Filter, double-click the Dell Wyse WF Disable icon on the desktop. This icon disables the filter and reboots the system. 3 Configure the thin client device as per your requirements. 4 After you configure the thin client device, to enable the Unified Write Filter, double-click the Dell Wyse WF Enable icon on the desktop. This icon enables the filter and reboots the system. Your configurations on the thin client device are now saved, and they persist after you reboot the thin client. After system start-up, the Unified Write Filter (UWF) utility starts automatically. You can add specific files or folders on a protected volume to a file exclusion list to exclude those files and folders from being filtered by UWF. When a file or folder is in the exclusion list for a volume, all writes to that file or folder bypass UWF filtering, 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 file or folder exclusions during run time, and you must restart the device for new exclusions to take effect. Running Unified Write Filter command-line options There are several command lines you can use to control the Unified Write Filter. Command-line arguments cannot be combined. Use the following guidelines for the command-line option for the Unified Write Filter. You can also use the commands if you open the command prompt window with elevated privilege by entering command in the Run box. Table 2.
