Most of what I've done (and continue to do on a daily basis) is geared to system automation. Whether you're managing tens of thousands of computers or managing a few of servers, one thing remains the same: To be efficient, you need to be able to manage all those systems easily from a central management point.

If you open Windows Task Manager, you'll see a bunch of running processes, most of which are processes that you don't use interactively ...
