How to install Composer on Windows 10?

Question

I am trying to install Composer on Windows 10, but the following error message is appearing:

The PHP exe file you specified Did not run correctly: C: Program Files Vertrigoserv Php php.exe

The php.ini used by your command-line PHP is: C: Program Files Vertrigoserv Php php.ini

A Setting in your php.ini could be causing the problem: Either the 'extension_dir' value is incorrect or the dll does not exist.

Program Output: Failed loading C: Program Files Vertrigoserv php ext php_xdebug-2.5.5-7.1-vc14. dll PHP Warning: PHP Startup: Unable to load Dynamic library 'C: Program Files Vertrigoserv php ext php_mysql.dll' - Could not find the specified module. in Unknown on line 0

As you can see, I use Vertrigoserv. I have tried running in administrator mode, I have tried with extension_dir commented and not commented.

Currently the php.ini file is like this in this snippet:

; Directory in which the Loadable Extensions (modules) resides.

; http://php.net/extension-dir

; extension_dir = "./"

; On windows:

extension_dir = "ext"
