Release Notes

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.

device connections for me in the XenDesktop connection preferences user interface.
Sysprep using User Interface
The System Preparation tool (Sysprep) can now be configured using the inbuilt user interface. Using this tool the data gets cleared from
the system and the system can be customized as per the requirement. The operating system will be like a new installation.
The Sysprep tool is used with other deployment tools to install the Microsoft Windows operating systems with minimal intervention by an
administrator.
Buildmaster.cmd is the main program that calls other executable files that prepares the thin client for the Windows installation.
Buildmaster.cmd is located in the<drive C>\Windows\Setup on all installations.
Sysprep must always be run from the <drive C>\Windows\Setup and must run on the version of Windows with which it was
installed.
The Sysprep tool contains the following two options:
• Custom Sysprep, see Running the Custom Sysprep tool.
• Config Sysprep, see Running the Config Sysprep tool.
Prerequisites
The following are the pre-requisites to run the Custom Sysprep tool:
• Unified Write Filter must be in disable state.
• Logging framework must be available on your thin client.
• Power Shell script execution environment must be available.
• Custom Sysprep and Configuration Sysprep (SCCM) scripts must be available.
• Host Name calculation feature must be available.
• If the flash size or HDD size is more than 32 GB, reduce it to less than 32 GB for a better custom sysprep process.
NOTE:
You cannot access the thin client if you terminate the Sysprep process. Make sure that the device is ready before
you use the Sysprep tool.
CAUTION: After you run the Sysprep tool, enable the Unified Write Filter to ensure device security.
