This has long bugged me. after upgrading to Windows 8, i already cannot run my XAMPP server without using ports other than port 80, since a process called "NT Kernel & System" is using it. It's a system process so I cannot disable it. I don't have any IIS or Web Server installed so I am pretty frustrated how to use that Port 80.
If anyone of you who knows how to change the port "NT Kernel & System" uses, that would be great!
Thanks!
I ran into this problem after installing just Apache 2.2.22 on Windows 8. What I'm strongly convinced of after scouring many forums for information is that the most common cause of this issue on Windows, which produces the "make_sock could not bind to address 0.0.0.0:80" error, is that IIS is running. Stopping the World Wide Web Publishing Service is what finally enabled Apache to start for me as well.
