Using SysprepUser Interface
The System Preparation tool (Sysprep) can be configured using the inbuilt user interface. Using this tool, you can clear the data
and customize the system as per your requirement. The operating system is installed as a fresh installation.
The Sysprep tool is used with other deployment tools to install the Windows operating systems with minimal intervention by an
administrator.
Buildmaster.cmd is the main program that calls other executable files and prepares the thin client for the Windows
installation.
Buildmaster.cmd is located in the<drive C>\Windows\Setup on all installations.
Always run the Sysprep file from the <drive C>\Windows\Setup and 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 disabled.
Logging framework must be available on your thin client.
Power Shell script execution environment must be available.

If the flash drive or HDD size is more than 32 GB, reduce it to less than 32 GB for a better custom sysprep process.
