you don't set the priority directly this way, rather you choose a
priority class (realtime, high, normal, idle; corresponding to 24, 13,
8, 4) and then a modifier (highest, above normal, normal, below normal,
lowest; corresponding to +2, +1, 0, -1, -2).

Is that correct? Shouldn't idle be 3 to allow the full 1-15 range?


According to sysinternals' Process Explorer, idle is indeed 4.  I
haven't double checked with anything on MSDN but I don't see why it
would not be displaying the correct thing, given that it shows the
priority on the 0-31 scale for every process so it must be using the
NTDLL level calls.

Hmm, that's pretty complex way to do things:


There is actually three levels: Background/Foreground process, base priority, and then special "thread priority" that has seven more modifiers.
