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
Double click and you will see the Disclaimer note as below
Port 80 / 443 check in windows in a single step
When you press any key , if ports 80 and 443 are already occupied, you will be shown what exact programs are holding that ports in this manner..
Port 80 / 443 check in windows in a single step
**** Note : If you see “FINDSTR: No search strings”, most of the time, Port 80/
443 is not held by any program.****

Or you can use TCPView v3.05
