Task Scheduler Tasks

Updated: December 6, 2007

Applies To: Windows Server 2008

A task is the scheduled work that the Task Scheduler service performs. A task is composed of different components, but a task must contain a trigger that the Task Scheduler uses to start the task and an action that describes what work the Task Scheduler will perform.

Managed Entities

The following is a list of the managed entities that are included in this managed entity:

Name Description

Task Scheduler Backward Compatible Tasks

A backward compatible task is compatible with Task Scheduler 1.0.  Task Scheduler 1.0 is used in the Windows XP, Windows Server 2003, and Windows 2000 operating systems.

Aspects

The following is a list of all aspects that are part of this managed entity:

Name Description

Event Trigger Task Registration

An event trigger starts a task when a specific system event occurs. You create a task with an event trigger by registering the task with the Task Scheduler service.

General Task Registration

To create a task, register the task with the Task Scheduler service. When a task is created, it is stored in a task folder. You can change the access control list (ACL) for a task or task folder to allow or deny certain users and groups access to a task or a task folder.

Idle Trigger Task Registration

Tasks can be started when the computer enters an idle state by defining an idle trigger or setting the idle conditions for when the task starts. To create a task with an idle trigger, register the task with the Task Scheduler service.

Task Monitoring and Control

The history of a task is tracked by events. These events can be viewed in Task Scheduler for each task to track when the task was registered, run, and when it completed or failed. The progress of a task can be monitored through its history. A task can be controlled by running or stopping the task manually (on-demand).

Task Properties

Task properties define the settings and conditions for running a task. A task will run if all of its conditions are met after the task is triggered to start. Conditions are divided into three categories: idle conditions, power conditions, and network conditions. The conditions for a task care displayed on the Conditions tab of the Task Properties or the Create Task dialog box in Task Scheduler.

Task settings specify how a task is run, stopped, or deleted. The settings for a task are displayed on the Settings tab of the Task Properties or the Create Task dialog box in Task Scheduler.

Wake Computer Task Registration

Tasks can be configured so they wake a computer from sleep mode to run the task. To create a task that wakes a computer from sleep mode, register the task with the Task Scheduler service.
