The catalogs that have been modified since they were last imported are displayed and can be imported from the Updates Publisher start page in the Catalog Updates pane. The import list contains information about the software updates catalogs, such as source location, publisher, and so on. For more information about adding catalogs to import lists, see How to Add Catalogs to the Import List.
