Vulnerability discussion

Active Desktop items could contain links to unauthorized websites or other undesirable content. It is prudent to prevent users from installing desktop items from this security zone. Installation of items must have a level of protection based upon the site being accessed. This policy setting allows you to manage whether users can install Active Desktop items from this zone.

Check content

Fix text

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Restricted Sites Zone -> "Allow installation of desktop items" to "Enabled", and select "Disable" from the drop-down box.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
