I am using XAMPPS to host PHP files from my machine. I have recently installed XAMPPs but I am unable to start Apache service as port 80 is in use by PID 4 - NT Kernel &
I have also faced the same issue while installing the XAMPP. The reason being the port 80 as configured in httpd.conf is already in use in other application (eg., in Skype). You can change the port value in httpd.conf to 8080 or other number. Click on config icon and open http.conf file. Search for 80 and do the following steps
In httpd.conf change
Listen 80 to Listen 8080
and
ServerName localhost:80 to
ServerName localhost:8080
You can check the ports used currently by clicking on netstatt icon in the XAMPP Control Panel
