One of the new tasks and scripts in the Microsoft Deployment Lite Touch Task sequence is called Windows Update. This task is disabled in the default task sequence for the Client Template. The task runs a script called ztiwindowsupdate.wsf. One item to note is that the current version of this script requires client access to the Internet and also does not support proxy authentication. However if you meet those requirements, there are some really nice advantages of using this action. Here is a brief description of what actions this script performs.
This script will install and download updates from Windows Update and Microsoft Update over the Internet using the Windows Update Agent API. By default this feature is disabled in each Task Sequence, it must be manually enabled to run, and each computer must have a connection via proxy to the Internet. This script was designed to run on Windows XP, 2003, Vista, and should be compatible with Windows Server 2008 when released.
