With the Priority options box, you can change the base priority of the process highlighted in the Process selection list box. This priority determines the activity of all threads of the selected process.
| Field | Description |
| Very High | Maximum priority. CPU time is split between this and other Very High priority processes. Lower priority processes execute only when all Very High priority processes are blocked. |
| Normal | Standard priority group, also known as foreground. Most applications run with normal priority. |
| Idle | Lowest priority group, also known as background. Processes with this priority execute only when the system has no higher-priority processes that need CPU time. Screen savers run at this priority. |
