also prevent undesired ash memory writes, and clean-up extraneous information from being stored on the local disk. The C-A-D tool

allows administrators to map the Ctrl+Alt+Del key combination of VDI applications to display the Ctrl+Alt+Del screen of the VDI application.

If the C-A-D tool is enabled, you can use the Ctrl+Alt+Del key combination for all VDI applications.

The Wyse Management Suite enables you to centrally congure, monitor, manage, and optimize your Wyse Software thin clients. To

manage the Wyse Software thin clients remotely you must register the devices to Wyse Management suite.

However, there are instances where administrators can retain the changed congurations after you log out and restart the Wyse Software

thin client.

Before conguring your Wyse Software thin clients, see

Unied Write Filter

Unied Write Filter (UWF) is a sector-based write lter that protects your storage media on a Windows 10 device. 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

device and reduces the wear on write-sensitive media, such as solid-state drives. In UWF, an overlay is a virtual storage space that saves

changes made to the underlying protected volumes. Any time the le system attempts to modify a protected sector, UWF instead copies

the sector from the protected volume to the overlay, and then modies the overlay instead. If an application attempts to read from that

sector, UWF returns the data from the overlay instead, so that the system maintains the appearance of having written to the volume, while

the volume remains unchanged.

CAUTION

: 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. Dell recommends you to enable write lter while

using thin clients. To make any changes on the system, administrators must disable UWF.

For more information, see the Unied Write Filter documentation at technet.microsoft.com.

Using Unied Write Filter

To congure the Wyse Software thin client to use UWF, do the following:

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.

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.
