WMI Event Watcher Task

The WMI Event Watcher task watches for a Windows Management Instrumentation (WMI) event using a Management Instrumentation Query Language (WQL) event query to specify events of interest. You can use the WMI Event Watcher task for the following purposes:

Ø  Wait for notification that files have been added to a folder and then initiate the processing of the file.

Ø  Run a package that deletes files when the available memory on a server drops lower than a specified percentage.

Ø  Watch for installation of an application, and then run a package that uses the application.
