Create WMI Providers to Notify Applications of System Events

摘要

Windows Management Instrumentation (WMI) is based on an industry-wide standard for notifications used to manage objects and devices across a network. By receiving WMI events, an application can be notified of changes to data in WMI itself. This allows the developer to notify the consuming application that certain system configuration data has changed, without the application having to poll WMI continuously for this data. The author presents an explanation of the different types of events in WMI, then goes on to develop an event provider.
