Working with Unified Write Filter utility

Unified Write Filter (UWF) is a sector-based write filter that you must use to protect your storage media. UWF intercepts all write attempts to a protected volume and redirects those write attempts to a virtual overlay.
WARNING:Failure to keep the Write Filter turned on (except for regular maintenance or Application/Driver installs or upgrades) will prematurely wear out your Flash/ SSD storage and invalidate your warranty.
For more information about UWF, browse Unified Write Filter on www.microsoft.com.
The Dell Wyse Write Filter (WF) guidelines are given below:
  1. Log in as an administrator.
    If automatic logon 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 will persist after a thin client device reboot.
