Event ID 709 — Backward Compatible Task Registration
Applies To: Windows Server 2008
A backward compatible task is a Task Scheduler 1.0 task that is used in the Windows XP, Windows Server 2003, and Windows 2000 operating systems. A Task Scheduler 1.0 task can be registered (scheduled) to execute any of the following application or file types: Win32 applications, Win16 applications, OS/2 applications, MS-DOS applications, batch files (*.bat), command files (*.cmd), or any properly registered file type.
You can register a Task Scheduler 1.0 task in one of three ways:
- Use the schtasks.exe command-line tool to define and register a version 1.0 task.
- Use Task Scheduler to define and register a task compatible with earlier operating systems. Click the **Create Task **action in Task Scheduler, set the Configure for box on the General tab to Windows Server 2003, Windows XP, or Windows 2000.
- Use Task Scheduler to import a Task Scheduler 1.0 task from an XML file.

Attempt to reregister a Task Scheduler 1.0 (prior to Windows Vista) compatible task and verify that the registration succeeds. You can register a Task Scheduler 1.0 task in three ways:
- Use the schtasks.exe command-line tool or the at.exe tool to define and register a version 1.0 task. The schtasks.exe tool is located in the %SYSTEMROOT%\System32 folder. Use the schtasks /? command to display the help for using the tool.
- Use Task Scheduler to define and register a task compatible with earlier operating systems. Open Task Scheduler and click the **Create Task **action, set the Configure for box on the General tab to Windows Server 2003, Windows XP, or Windows 2000.
- Use Task Scheduler to import a Task Scheduler 1.0 task from an XML file. Open Task Scheduler, click the Import Task action, navigate to the XML file that defines the task, and then click the Open button.
After you register the task, open Task Scheduler, select the task in the task folder hierarchy, and click the History tab for the task to verify that it contains events indicating the task was registered successfully.
