Apache does not start on port 80

Question

First, I wanted to see what was using port 80:

C:\Users\[my user]>netstat -aon | findstr :80
TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       4
TCP    192.168.1.46:57822     72.21.91.29:80         TIME_WAIT       0
TCP    [::]:80                [::]:0                 LISTENING       4
C:\Users\[my user]>

See what I had in PID 0 and 4:

I did not have an application using port 80 from what I see. I would think that port 80 is free for an application such as Apache to use it. In the following screen, I click "Start Apache" and nothing happens. That was how I always used to start Apache.

I am trying to start Apache on port 80:

If I use a different port such as 81, 82, 83, etc., it works. But I want to use port 80 because I do not want to use http://localhost:81/ in the URL to test my site. I simply want to use http://localhost/.

Do you have an idea about why I am not being able to start the Apache service on port 80 even though apparently port 80 is free? Or maybe it is not free because this PID 4 is using it? The name of that process is System.

@MartinParkin I recently installed Microsoft SQL Server 2012 and if I suspect that things stopped to work correctly for me for Apache after I installed this SQL Server. — Jaime Montoya, Dec 18 '18 at 00:20
Check for the `World Wide Web Publishing Service` running in your services. I would speculate that this is using port 80 and preventing you from doing so. Its service name is `W3SVC` — Martin, Dec 18 '18 at 00:24

This solution was listed in the duplicate link I posted. – Madison Courto Dec 18 '18 at 00:28
Sorry, I can't see where you posted a link to a duplicate providing the solution I posted, am I missing something? – Madison Courto Dec 18 '18 at 00:33
I do not see the `World Wide Web Publishing Service` service running. – Jaime Montoya Dec 18 '18 at 00:37
Did you run "NET stop HTTP"? – Madison Courto Dec 18 '18 at 00:38
Or look at the duplicate link? – Madison Courto Dec 18 '18 at 00:39
I had a permissions issue when trying `NET stop HTTP`. I will use a port different than 80 because now I do not see the port number in the URL. See my answer to my own question. – Jaime Montoya Dec 18 '18 at 15:05

I am using a different port instead of 80. Not a big deal, I would have preferred to use port 80 but I can cope with not using it. That is fine.
