As I understand it, they're almost the same thing - mutexes work with
multiple threads in an single application, critical section objects
work with multiple threads in a single process. It doesn't help things
any that "critical section" is also used to refer to the code governed
by a mutex.

Here's a fairly concise, albeit microsoftian, writeup:
