Manage Trusted Publishers

Applies To: Windows 7, Windows Server 2008 R2

Software signing is being used by a growing number of software publishers and application developers to verify that their applications come from a trusted source. However, many users do not understand or pay little attention to the signing certificates associated with applications that they install.
