However, there are instances where administrators want configurations to persist even after logoff and
restarting a thin client.
Before configuring your thin clients, see

NOTE: To configure and manage multiple thin clients, see Dell Cloud Client Computing.
Working with Unified Write Filter Utility
Unified Write Filter (UWF) is a sector-based write filter that you can use to protect your storage media.
UWF intercepts all write attempts to a protected volume and redirects those write attempts to a virtual
overlay. UWF improves the reliability and stability of your client and reduces the wear on write-sensitive
media. For more information about UWF, browse Unified Write Filter in 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

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 reboot the system. Your configurations on the thin client device are
now saved and they will persist after a thin client device reboot.

Brief Introduction about NetXClean Utility
NetXClean is a clean-up that keeps extraneous information from being stored on the local disk. If you
want to retain certain profile configurations such as printers, monitors and other peripherals, be sure to
configure NetXClean in order to refrain from cleaning up explicitly declared profiles.
For more information, see Understanding the NetXClean Utility.

Connecting to a Printer or an External Device
You can connect to direct USB interface printers or to parallel printers to your thin client device through a
USB port. For parallel printers, ensure that you have a USB-to-parallel printer adapter cable. You also
need to install the driver for the printer by following the printer driver installation instructions.
