WampServer installs automatically (installer), and its usage is very intuitive. You will be able to tune your server without even touching the setting files.

WampServer is the only packaged solution that will allow you to reproduce your production server. Once WampServer is installed, you have the possibility to add as many Apache, MySQL and PHP releases as you want.

WampServer also has a trayicon to manage your server and its settings.
