This ISAPI filter removes the index.php from WordPress's permalinks on IIS,making your permalinks more pretty and SEO friendly.

Because IIS does not support mod_rewrite module for rewriting URLs, so whenever you try to use permalinks, you always get something like this:

http://www.yourdomain.com/index.php/2006/09/02/...../

this filter can remove the index.php from url automatically.it's easy to use,just install it and no further configuration is necessary.
