Google for "AutoIt".
A blurb from their website http://www.hiddensoft.com/AutoIt/index.php
"AutoIt was primarily designed to assist in automatically installing software that cannot be automatically installed by other means. This is most useful during a PC rollout where hundreds or thousands of client machines need to be automatically installed. However, AutoIt is not limited to software installation and can be used to automate most simple windows tasks."
