Allow users to manage installed CA certificates.
Setting the policy to All (0) or leaving it unset lets users edit trust settings for all CA certificates, remove user-imported certificates, and import certificates using Certificate Manager. Setting the policy to UserOnly (1) lets users manage only user-imported certificates, but not change trust settings of built-in certificates. Setting it to None (2) lets users view (not manage) CA certificates.
Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
