In My PC, I am running :

telnet localhost 80

and it seems that there is an answer.
No IIS runs, no java server runs.

Open command prompt as administrator and run the below command

C:\>netstat -a -b

netstat is used to display information and statistics about the network connections. The flag -a makes it display all connections and listening ports and the flag -b makes it show the associated executable.
