Task History List
The Remote Desktop sidebar includes a Task History group, which is automatically created as individual tasks are completed. If you need to repeat those tasks (either on the same computers or on different computers), you can double-click them and work with them in much the same way as you would a saved task. You can even choose to save a task from the Task History after it has been run. You can specify how many recent tasks are stored in the Task History as well as how long tasks will be stored for using the Tasks pane in the Remote Desktop preferences.
