Here is a task manager that I came across a while ago. It never really got a lot of hype, but I think it is really a great app. Forgive me if it has been posted before.

It shows Processes, CPU usage, Applications, Services, Devices, Notifications (and can remove duplicates), it can ping and configure the IP, shows Network stats, and has a FREE REGISTRY EDITOR.
Edit: Just saw that perhaps this post belongs in the "Software" section. Sorry
