open the php.ini-production file in c:\php and uncomment the following lines
fastcgi.impersonate=1
cgi.fix_pathinfo=1
set cgi.force_redirect=0 and uncomment it
set fastcgi.logging=0 and uncomment it
then rename the file php.ini-production to php.ini and save it to c:\windows
then restart ur server and run this program u'll find the changes
<?php
phpinfo();
?>
