Windows 7 / Getting Started

Task Scheduler Events

In Windows Server 2003 and earlier versions, scheduled tasks used a Schedlgu.txt log file to track tasks and their status. Windows Vista implements all new event logs for applications, and Task Scheduler now logs all operational information about scheduled tasks into its own event log. The Scheduled Tasks event log Microsoft-Windows-TaskScheduler is located under Application Logs. Important errors or warnings about task or service failures are logged to the System log so that administrators can readily see them and take action.

Task Scheduler 2.0 will normally log an event on task registration (at creation), at task launch, and when the task instance has been sent to the engine. Events will also be logged on task failures and any task-related problems. This section provides examples of typical events that are logged by the Scheduled Tasks service.

Task Registration

An Event ID 106 is logged when a task is created. This event is also referred to as task registration.

Task Launch

Tasks can be started by either a user request or a trigger. An Event ID 110 is normally logged when a user manually starts a task. An Event ID 107 is normally logged when a task is started as the result of a trigger.

Task Execution

An Event ID 319 indicates that the Task Engine received a message from the Task Scheduler service requesting task launch, and it is the best indicator of a task launch. In these events, the Task Engine is identified by the user SID, and the task name is also logged.

Task Completion

An Event ID 102 is normally logged when a task completes successfully.
