Comment (by JanR):

 Replying to [comment:5 ocean90]:
 > [attachment:misc.php.patch] looks good. What happens if I have an
 existing install with the old rule and update to 4.5?
 `iis7_add_rewrite_rule()` wouldn't find the old rule and the new one is
 added as a duplicate rule with a different name?

 `WordPress`?

 Not easily, xPath 1.0 is not case sensitive, and lacks `to-lower` / `to-
 upper` functions like xPath 2.0 has, so you need to work around that and
 hack something together. Meaning a proper rewrite of the
 `iis7_add_rewrite_rule()` function.

 If someone's up for the job, some more information is available at
 http://www.cowburn.info/2009/10/23/php-funcs-xpath/ and

 If @WiZZarD_ needs my help he knows where to find me :)
