I am not able to kill process bound to 8000 port, due to which I am not able to start HTTP server. This is in reference to question Start HTTP/HTTPS server, python -m SimpleHTTPServer

C:\>taskkill /f /pid 4
ERROR: The process with PID 4 could not be terminated.
Reason: Access is denied.

Even killing by below is not working which I found somewhere. 

C:\>taskkill /f /s localhost /pid 4
ERROR: The process with PID 4 could not be terminated.
Reason: Access Denied.

PID 4 is system process, what might be running on there, how do I stop it, why are other ports is a similar fashion listening. 

C:\>netstat -ab

if you're in Windows this might help you, the port 80 is usually being used by this service: "World Wide Web Publishing Service", open "Services" in the Control Panel and stop it
