WhatsRunning is up to V2.1. It’s a program that lets you see … uhh … what’s running on your system. From processes to IP connections to startup programs and more. Not only is the program worthwhile but the site itself has a section called Process Information Central which can identify what a process is, what it does and what company it’s from.
The program is free for non-commercial use, $US 25 otherwise.
Another good site that I’ll just mention here and do a more thorough write-up later is AnswersThatWork. Try their Task List for something similar to What’s Running’s Process Information Central.
