Remarks

Priority level 0 is the highest priority, and priority level 10 is the lowest priority. The default value is 7. The minimum and maximum values are set by the priorityType simple type. Priority levels 7 and 8 are used for background tasks, and priority levels 4, 5, and 6 are used for interactive tasks.

The task's action is started in a process with a priority that is based on a Priority Class value. A Priority Level value (thread priority) is used for COM handler, message box, and email task actions. For more information about the Priority Class and Priority Level values, see Scheduling Priorities. The following table lists the possible values for the Priority element, and the corresponding Priority Class and Priority Level values.
