Your favorite Sysinternals utility?

To help debug my macro recorder, I have used DebugView lots. Recently,
Process Monitor helped debug a problem with Logitech's lousy SetPoint
software. It is a bear to use, unless you already know (or until you
figure out) how to use filtering.

Autoruns is probably one I should have been using already, instead of
looking in MSconfig or searching the registry.
