How to Check What’s Using Port 80 or 443 in a single step : Web port Inspector

Sometimes, when you try to install application/program that is going to listen on port 80 or port 443, you will get notorious messages when port 80/443 is already occupied.. Yet you have no clue to find out what program already holding 443 or port 80.  When you are trying to install xampp you will get error message similar to “XAMPP Port 80 in use by “Unable to open process” with PID 4” or when you try to install wamp and turn on apache you will get “Your port 80 is actually used”

Pretty annoying and rather frustrating if you don’t know how to find which port is occupying afore said ports…

To open a port, a process/application should be installed and configured to listen to port 80/443.. Typically if you are using  web servers such as  IIS/wamp/xamp/apache/nginx with http/https or applications such as teamviewer/skype there is possibility to see  443/80 port is opened by that programs.

Normally, what you can do is, open a command prompt and type netstat ao grab the PID which holds port 443 or port 80 and then enable PID in task manager and check the application .. 

Instead ,what if you could get everything in a single step?

You can use Fport v2.0 by mcafee, unfortunately mcafee Fport v2.0 not compatible and not working on windows 8 / windows 8.1 and later operating systems.. So what next? Web_Ports_Inspector ( a combination of tasklist | findstr) would be a great alternative for mcafee Fport v2.0 and it works all most all windows operating systems..

Download Web_Ports_Inspector.bat
