I built a search provider for Windows 7, running on localhost. (using .osdx file and RSS web site) the element in the returned RSS contains local file path.
example: <link>c:\windows\win.ini</link>
The problem is that the files shown in the search result window with the following message:
This item was blocked because of your Internet security settings
How to prevent this security restriction?
you have to add the intranet zone and modify its security settings to allow this content. http://support.microsoft.com/kb/174360 -- security zone registry settings
