windows 10, Xampp, Apache will not start, port 80 in use

Viewed 7240

Trying to install and launch Apache from Xampp... Error message: "Problem detected! Port 80 in use by "Unable to open process" with PID 4!" No answer found in previous posts.

ctrl+alt+del >details give: PID4: Système et mémoire compressée fichier ntoskrnl.exe, fin de tâche impossible

Xampp suggests: "reconfigure Apache and the Control Panel to listen on a different port"
port 80 appears in
- apache config > httpd.conf (listen 80) and Servername localhost: 80 - confif > service and port settings > only for Apache mainport 80

Will it be enough to change these two value eg to 8080 as some posts suggest?

Thanks for any advice

I had the same issue in windows, i have followed following steps to resolve it.

  • Go to Program And Feature from Control Panel
  • Click on "Turn Windows Features On or Off" from the left side bar (Windows Features Modal will be opened)
  • Find "Internet and Information Services" from the feature list
  • Uncheck the checkbox of it
