Cluster-Aware Updating Provider Reference
The WMI provider for the Cluster-Aware Updating (CAU) tool allows you to coordinate with CAU when performing non-CAU updates, and it provides the back-end implementation of the default plug-in, which uses the Windows Update Agent (WUA) to scan, download, and install updates through Windows Management Instrumentation (WMI). This documentation assumes you are familiar with the concept of WMI and have experience writing WMI scripts and applications.
