The good folks over at UniBlue have released a Instant Process Scan that can tell you what those proccesses are and what they are doing! The first app is a small install that creates a detailed report for you of your running processes. They even give you recomendations on next steps related to each entry. The second tool is a Task Manager Plugin - ProcessQuickLink that gives you process information - Right in the task manager! Sweet.
