1) I am assuming you have WAMP Installed already, if not, first proceed to wampserver.com and download the latest version. Once installed, launch it, type http://127.0.0.1
on your browser, and make sure you see the default screen. And just in case your post#80 is already used for something else, here is a guide to changing WAMP servers default port.
2) Download Drupal - I'm using the v7.14 .zip version. Unzip into a dir at: C:\wamp\www, for example: C:\wamp\www\drupal - where drupal is the main directory containing all the drupal files.
3) Create a database in WAMP using PHPMyadmin. Make sure you have the following info ready: database name, username and password.
4) To begin installation, type: http://127.0.0.1/drupal
. You should see a page displayed similar to the below. By the time we finish, all the processes at the left hand side must have a green-check mark.
