First you will need to search and download XMAPP, LAMP or WAMP. These are a bundled packages of the Apache server, PHP and MySQL. For this excersice we will assume we are using XAMPP (my personal favorite) Once this is installed you can procced with the installation of Joomla. You can download XAMPP from ApacheFriend or here.
Install by extracting the XAMPP folder to your root drive or the C:/ drive. You can find out if XAMPP and Apache server is installed correctly by typing http://localhost or http://localhost/xampp in your browser and pressing enter
Search and download Joomla compressed file usually in .zip file. You can download latest Joomla from Joomla or Joomla 1.5 from our database. Extact the Joomla .zip files into htdocs folder, usually located at C:/xampp/htdocs
Open your browser and type http://localhost/joomla
You will now see the first Joomla installation screen.
