Revert Key Tasks to Standard Tasks

You can change a key task into a standard project task. Use the Key Tasks tab on the Project Properties dialog to remove the key task designation. You can view the changes that you make on the General tab on the Task Properties dialog and in any view that displays the key task field name.

Note: When you remove key tasks from the grid on this tab, only the key task designation is removed from the task. The tasks are not removed from the project.

Follow these steps:

1. Click Project Properties in the application menu.
2. Open the Key Tasks tab.
3. Select the row for the key task you want to revert to a standard project task, and click Remove.
4. Click OK.
