The Microsoft.Windows.WmiProvider module is a data source module type that queries a Windows Management Instrumentation (WMI) namespace at a scheduled frequency and returns the results as System.PropertyBagData type data.

Usage

Use this module when you want to query for WMI objects and return the data within a workflow such as a rule or monitor.
