Technical overviewThe System Registry provider creates several methods and event classes that allow Windows Management Instrumentation (WMI) scripts or applications to interact with the registry. You can subscribe to several registry events. For example, you can subscribe to the changes in a registry key, in a sub key, or in a registry key value. This sample code uses the RegistryKeyChangeEvent class that represents changes in a specific registry key.
To subscribe to RegistryKeyChangeEvent events, create a WqlEventQuery object and use the ManagementEventWatcher class to watch these events. When a change occurs, the EventArrived event of the ManagementEventWatcher class is raised.
- RegistryEvent classes (for example, the RegistryKeyChangeEvent class) do not support changes in the "HKEY_CLASSES_ROOT" and "HKEY_CURRENT_USER" hives.
- The WMI event does not return the changed value and changed type. The WMI event only shows that there is a change. The properties that you can get from the event are Hive, KeyPath, SECURITY_DESCRIPTOR and TIME_CREATED.
