Windows Update Agent

The Windows Update Agent component provides critical operating system updates to the user, including driver updates, security fixes, and application updates. This component requires a Microsoft Software Update Services (SUS) server to communicate with the Microsoft Windows Update Web site and obtain updates; this component does not directly communicate with the Windows Update Web site.

This component also includes the Automatic Update tab in the System Properties dialog. Automatic Update (AU) runs as a local service, which cooperates with a process in the current user's context to download and install updates that a SUS server obtains from the Windows Update Web site.


This component provides the Windows Update Agent service named Automatic Updates.
