I use these regularly to see and control what’s running on my PC. TCPView lets you see what processes are connecting to web servers, Process Explorer is a more detailed approach to Task Manager, and Autoruns is particularly effective at allowing you to limit what starts at boot time.
There is a lot of other geek stuff available in this collection, but these 3 are my daily, go to tools!
