Trusted Publishers and Credentials Agencies
This list controls whose software can be installed on your
system without asking you first.
The list can contain both individual software publishers 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 system without
asking you first.
