Port 80 Windows 7 64bit

At the outset, let me say I'm on Windows 10.

OK, opening a port in Windows Firewall is fine. But, um, I'm not using Windows Firewall.

In Services, I have long ago stopped and DISABLED the service for Windows Firewall (MPSSVC)

In Services, I have long ago stopped and DISABLED the service World Wide Web Pubilishi8ng Service (W3SVC)

And STILL I have a monopolized port that shows up in WinInternals TCPVIEW as being opened (as a LISTEN) by some process called SYSTEM on PID 4. Now, I know I can't get rid of that (or I can, but that's a major OS move). So, what did I do wrong.  Or did MS simply but high-handedly take control of port 80 from now on. I don't use IIS. This is dumb. There must be another process to kill, Could it be that the IIS Admin Service (IISADMIN) is holding things open just in case, not simply on port 8098 or whatever it uses, but holds open port 80 on all interfaces?  That's high-handed, too.  I just now stopped it, disabled it, and there's been no change. I'm hoping a restart will loosen things up. Otherwise I'll have to use a 3rd party for some of the basic services. SMTP, FTP, etc. as it seems this all started when I added the "simple' services.  I don't need this headache that can't be cured.

And I already HAVE a firewall, thank you very much.

I am doing some tests and I need port 80 to be open.

I followed all the steps you have described above of how to open port 80, but when I use netstat command this port showed to be closed.

I do not know what to do.

Why?

Open a port in Windows Firewall

If Windows Firewall is blocking a program and you want to allow that program to communicate through the firewall, you can usually do that by selecting the program in the list of allowed programs (also called theexceptions list) in Windows Firewall. To learn how to do this, seeAllow a program to communicate through Windows Firewall.

However, if the program isn't listed, you might need to open a port. For example, to play a multiplayer game with friends online, you might need to open a port for the game so that the firewall allows the game information to reach your computer. A port stays open all the time, so be sure to close ports that you don't need open anymore.

1. Click to openWindows Firewall.
2. In the left pane, click Advanced settings.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3. In the Windows Firewall with Advanced Security dialog box, in the left pane, clickInbound Rules, and then, in the right pane, click New Rule.
4. Follow the instructions in the New Inbound Rule wizard.
