WordPress 2.5 Error on Windows IIS:Undefined index: PATH_INFO

After upgrading to WordPress version 2.5 on Windows IIS,you may get the following errors:

Notice: Undefined index: PATH_INFO in (path)\wp-settings.php on line 74
Notice: Undefined index: PATH_INFO in (path)\wp-settings.php on line 77 

to solve this problem,open file wp-settings.php,goto line 71 and replace the following code:

if ( $_SERVER['PATH_INFO'] == $_SERVER['SCRIPT_NAME'] )
	$_SERVER['REQUEST_URI'] = $_SERVER['PATH_INFO'];
else
	$_SERVER['REQUEST_URI'] = $_SERVER['SCRIPT_NAME'] . $_SERVER['PATH_INFO'];

with:

if (empty($_SERVER['PATH_INFO']))
	$_SERVER['REQUEST_URI'] = substr($_SERVER['SCRIPT_NAME'], 0, strrpos($_SERVER['SCRIPT_NAME'], '/')) . '/';
else if ( $_SERVER['PATH_INFO'] == $_SERVER['SCRIPT_NAME'] )
	$_SERVER['REQUEST_URI'] = $_SERVER['PATH_INFO'];
else
	$_SERVER['REQUEST_URI'] = $_SERVER['SCRIPT_NAME'] . $_SERVER['PATH_INFO'];

this will resolve that issue,Your can also download an already modified version of wp-setting.php from here.
