Opening up Port 80 for MAMP

Question

Unable to use MAMP as port 80 is supposedly being used by something else.

Above image shows that port 80 is already listening but by what? Need help on 'killing' that connection. Perhaps a command that can kill all port 80 connections? Tried unchecking the 'use port 80' command on Skype and no luck.

Answer 1

the last column is the PID of the corresponding program. Find it with tasklist /fi "PID eq 4" , kill it with taskkill /f /pid 4
