This change prevents the loading of mscorie.dll for a .NET control on a page, if that control's URL has a "DISABLED" policy for the new 0x2005 UrlAction. Please note that this URLAction cannot be configured via the Internet options control panel. This change is further discussed here.
Mscorie.dll contains a Multipurpose Internet Mail Extensions (MIME) Type Filter. This filter hooks into Internet Explorer and monitors all incoming data streams with the MIME type application/octet-stream. A primary role of this filter is to examine the incoming stream to see whether or not the stream is managed code. If the filter determines that the incoming data is a .NET Framework module, the filter loads a managed assembly named IEHost which then handles loading the .NET control. The following KB article discusses this in more detail:
If you want to allow loading .NET controls for any web site that is impacted by this change, you can add it to the trusted sites zone. Please note that the site that needs to be added is that of the control and not that of the page. Alternatively, you can set the above URLAction to enable in the registry. NOTE: This can compromise the security of your system.
