Apache Friends Support Forum

With my recent upgrade from Win7 to Windows 10, I discovered that Win10 System account loads http.sys to listen on port 80, so I had to temporarily set Apache to listen on port 81.

Has anyone found a reliable mechanism to stop Windows 10 from grabbing port 80? I tried the expedient of disabling http.sys in the registry, but that caused all the printers to not be available. Grrr.

So, for now, I'm using port localhost:81 for my XAMPP development system.

Best regards,

Maybe this will help:

I am using Windows 10 too on my development system but my system don't start http.sys on startup (i don't have any printers on my dev system, so maybe that is the reason)

Ok, I think I answered my own question

Using the Services panel in Computer Management, I stopped "World Wide Web Publishing Service" (nee IIS, I think), and changed it to 'Disabled'.

Then XAMPP Apache could be stopped, config changed to use port 80, and restarted successfully.

Now I'm happy again...
