Inorder to have win32 styled Apache directory indexing , you need to make sure that mod_autoindex module is installed and active in the server. In cPanel 11 servers, it will have the modules enabled in, /usr/local/apache/conf/extra/httpd-autoindex.conf
So for the client who want to have the fancy directory indexing to be enabled, just add the below lines to his .htaccess
Options +Indexes
IndexOptions FancyIndexing VersionSort
