How to Manage Windows Embedded Write Filters Using Configuration Manager 2007

Updated: April 1, 2011

Applies To: System Center Configuration Manager 2007, System Center Configuration Manager 2007 R2, System Center Configuration Manager 2007 R3, System Center Configuration Manager 2007 SP1, System Center Configuration Manager 2007 SP2

For a sample script that can be used with Configuration Manager 2007 to automate the configuration of the Windows Embedded write filter before and after the installation of software and software updates, see Example Script for Configuring Write Filters Using Configuration Manager 2007 on Windows Embedded Devices.

To use the script and perform software distribution and software updates management using Configuration Manager 2007 on Windows Embedded devices that use the Enhanced Write Filter (EWF) or File-Based Write Filter (FBWF) write filter, you must take the following steps:

  1. Create a software distribution package for deployment of the VBScript that contains the following programs:

    • Program 1: Issues the command to disable the write filter.

    • Program 2: Issues the command to enable the write filter.

  2. Create a custom task sequence that performs the following tasks:

    • At the command prompt, to set the default scripting host to CScript, type: cscript.exe //b //H:cscript

    • Run Program 1 to disable the write filter.

    • Perform the required software distribution and software update activities.

    • Run Program 2 to enable the write filter.

  3. Deploy the task sequence to devices in your organization.

noteNote
The sample script has been written to run safely on any operating system, but it has been tested only on Windows XP Embedded images. Test the script thoroughly before running the script on other systems.

Use the following procedures to create a software distribution package and programs containing the sample script and to create and deploy the task sequence to install the script on Windows Embedded devices in your organization.
