This list controls whose software can be installed on your computer without asking you first.
The list can contain both software publishers who are individuals and commercial software publishers. Software that has been published by a publisher in this list can be installed without your explicit approval.
The list can also contain one or more credentials agencies. Similar to a notary, a credentials agency is an organization in the business of attesting to the identity of software publishers. If a credentials agency is in this list, then any publisher certified by that agency is considered trusted, allowing software they publish to be installed on your computer without asking you first.
