Automatically Responding to Events
One of the most useful ways to use Task Scheduler is to launch a task in response to a
specific event type that appears in Event Viewer. You can respond to events in three ways:

Start A Program – Launches an application. Often, administrators write a script that carries
out a series of tasks that they would otherwise need to manually perform, and automatically
run that script when an event appears.
Send An E-mail – Sends an email by using the Simple Mail Transport Protocol (SMTP)
server you specify.
Often, administrators configure urgent events to be sent to a mobile device.
Display A Message – Displays a dialog box showing a message. This is typically useful only
when a user needs to be notified of something happening on the computer.
To trigger a task when an event occurs, follow one of these three procedures:
Find an example of the event in Event Viewer. Then, right-click the event and click Attach
Task To This Event. A wizard will guide you through the process.
