What program in Windows 10 uses port 80?

Question

I updated my Windows 7 PC to Windows 10. When I start AMPPS it says port 80 is used by another program. What program uses port 80?

Answer 1

It's probably the W3SVC (World Wide Web Publishing Service) service. See the answer below:

Per phpvillian's answer, you can also run the following to help determine the culprit (make sure you open the command line with elevated privileges, e.g. "Run as administrator"):

netstat -a -b 

Answer 2

You're likely referring to Skype as it's notorious to using port 80 without consideration. Open the command prompt and type netstat -a -b to get your answer. This question has been answered already and explains how to use netstat.

How can you find out which process is listening on a port on Windows?

Answer 3

I had same problem but already solved. You can find used port from Windows Firewall.

1. Click Start > Settings > Ethernet >Network and Internet > Windows Firewall
2. In the left pane, click Advanced Settings
3. In Windows Firewall with Advanced Security, click Inbound Rules.
4. Find Local Port 80 with Protocol TCP. in my case is "World Wide Web Services (HTTP Traffic-In)"
5. Once you find it, stop or disable that rule from Windows Services (World Wide Web Publishing Service).

if needed restart your pc.
