Save a Process Priority in Windows 7 | 8 Task Manager

I guess that all of you understand what is process priority and how to change it. But I'm sure that you have no idea how to save the priority, so if you re-launch the process, they have same priority without changing manually.
The steps:

1. Open Task Manager
2. Right click on the process you want to change
3. Set priority
4. Select the priority
5. Check 'Save Priority'

Wait, there is no 'Save Priority' button. Is there any error on my Task Manager?
No, that's happened because you haven't installed Prio – Process Priority Saver
