I installed XAMPP 1.6.8 and for some reason it didn\'t work. Later realized port 80 is not free or not listening. How can I release it or make it free?
That will show you the PID of the process that is listening on port 80.
After that, open the Task Manager -> Processes tab. From the View -> Select Columns menu, enable the PID column, and you will see the name of the process listening on port 80.
