Hello, at first You need to know that couple of things prevent running Apache on your Windows because port 80 is blocked by another application/s. Here's what I do when I have problems with this.

At first You need administrator privileges to do this.

  1. Open Windows PowerShell or Command Prompt in admin mode(right click windows icon in bottom left corner) then type "net stop http" and confirm, then run apache on port 80.
  2. Change Apache port to do this in XAMPP: Click config button, choose httpd.conf, find line "Listen 80", then change port for example to "Listen 81", now you can use your locals in browser address by typing "localhost:81/wp", assuming you have "wp" directory.

I prefer 1st method.

Optional: Also from my experience apache can make troubles when: Skype is running and UAC in windows is enabled(to disable this type 'uac' in windows search, but this will make your pc less secure so watch out).

Don't forget to place your project in "xampp\htdocs" directory.

Hope it helps.

Konrad.
