Related, have a look at the Sysinternals tools [1], particularly Process Explorer [2], a powerful "Task Manager" replacement.

Sysinternals used to be Mark Russinovich's external company that provided expert Windows debugging. His blog was impressive, and my little finger tells me he knew more about Windows internals than Microsoft did.

So Microsoft acquihired Sysinternals, and his tools continue to be supported :)

As for Process Explorer, the open-source Process Hacker is even better: https://github.com/processhacker/processhacker
