WMI events

You can also register for events coming from WMI classes or by using WQL queries. WMI stands for Windows Management Instrumentation and can be used for various OS automation purposes. Many cmdlets use WMI/CIM internally. As an operations or development person, you, for example, want to watch for modifications to the Windows service you deployed. With a WMI watcher, this can be achieved rather elegantly.

Moving on to the Common Information Model (CIM), the same learning applies to the Register-CimIndicationEvent cmdlet to register for CIM events not only on Windows, but also on, for example, Linux operating systems.
