Permanently change process priority?

I am attempting to permanently change process priorities for certain
apps on XP sp3 so that when I start them they start with a custom
priority of my choosing rather than with the default priority of
'Normal' assigned by XP.

I have tried both Prio and SetPriority, but neither app will permanently
assign process priorities. When the app which is assigned a priority
other than the default is closed and reopened, it reopens with the
default priority of Normal rather than with the one of my choosing.

I have .NET 2.0 installed, which is needed for SetPriority.

Can anyone shed any light on why these apps might not be working? Would
any particular service be needed to enable these process
priority-setting apps to work correctly?

Here's something I used for awhile a couple years ago (but don't use anymore
but forget my reasons after all this time):

According to them, their free version includes "persistent priorities".
