I built an AMD system a few days ago, I used the same SSD which I used in the previous system. Initially, I had issues on Windows reactivation on the new device, I called Microsoft support and they advise to reinstall Windows 8.1, then upgrade to Windows 10. After that, i tried to reinstall everything. Ammps is now my favorite PHP server, it has more features that Xampp. Installed other tools like Docker Toolbox, Vagrant etc. Later I just open my PHP project, start Ammps, but got a weird message “Port 80 is used by other processes“, I tried a couple of Windows command to see ports and pids, but pid number is 4, and it was a system process. Uninstall docker, but got same issues. I searched a lot, and from Microsoft forum, I got the result, it says that some Microsoft process related to IIS is using port 80. Below steps can use to free up port 80.
