Individual thread priorities, offsets of the base priority class.

The process priority class raises or lowers all effective thread priorities in the process and is therefore considered the 'base priority'. Similarly, real-time is also a thread priority level. Therefore, it is different from 'High' in that it's one step greater, and 'Above Normal' in that it's two steps greater. Real-time is the highest priority class available to a process. However, such a thread should not require much CPU - it should be blocking most of the time in order for normal system events to get processing. I imagine that multimedia drivers and/or processes might need threads with a real-time priority.

Note that there's absolutely no problem with a thread having a Real-time priority on a normal Windows system - they aren't necessarily for special processes running on dedicatd machines. Russinovich's "Inside Windows" chapter on how Windows handles priorities is a great resource for learning how this works: So a High priority thread won't get any automatic temporary boost into the Real Time priority class. It also won't boost the priority of threads in the real-time priority class. Windows will sometimes boost the priority of a thread for various reasons, but it won't boost the priority of a thread into another priority class. Oh yeah - you have to have the SeIncreaseBasePriorityPrivilege to put a thread into the Real Time class. I don't think there's much more to it than that. Simply, the "Real Time" priority class is higher than "High" priority class.
