Uninstalling Addons Using the FTP Addon Installer

You can use the FTP Addon Installer dialog box to uninstall the thin client Addons that have been installed with the FTP Addons utility.

Use the following guidelines:

1.Log-in as an administrator and open the FTP Addon Installer dialog box (Start Control Panel FTP Addons).

2.Select the Addon to be uninstalled from the Addon List.

3.Click Uninstall. The thin client reboots to disable the Write Filter, the Addon is uninstalled, and then the thin client reboots to enable the Write Filter.

Note

If you uninstall an Addon that is included in the Auto add-on upgrade list, that

Addon will be automatically removed from the list.

Caution

If you remove an Addon using the Windows Add or Remove Programs utility after disabling the Write Filter, the thin client must be rebooted once to update the Addon List in the FTP Addon Installer dialog box and enable the Write Filter.

Using Windows Server Update Services (WSUS) on a Thin Client

This section describes how to use WSUS to automatically deploy software updates on a Wyse thin client running Windows XP Embedded. Before using WSUS to deploy software updates, the server must be properly configured for WSUS.

Configuring the Thin Client for WSUS

The default Windows XP Embedded installation on a thin client does not allow users who are not administrators to receive update notifications. To check the update notification status on a thin client, do the following:

1.On the thin client, click Start Run. In the Run box, enter gpedit.msc.

2.Navigate to Computer Configuration, then Windows Components, then Windows Update. If the “Allow non-administrators to receive update notifications” option or GPO does not appear, you need to modify the wuau.adm file on the thin client.

To modify the wuau.adm file to allow non-administrators to receive update notifications, follow these steps:

1.Disable the Write Filter on the thin client.

2.Copy the wuau.adm file from the Windows 2003 server or from the Windows XP operating system into the c:\windows\inf folder.

3.Enable the Write Filter on the client.

Note

The thin client must be part of a group or GPO configured on the server that distributes the updates.
