General Information
Executive Summary
Microsoft is aware of Microsoft certificate authorities that are outside our
recommended secure storage practices. Upon a routine review, we are placing
these certificates in the Untrusted Certificate Store, and replacing them with
new certificate authorities that meet our high standard of public-key

certificate authorities, but are taking pre-emptive action to protect
customers. This issue affects all supported releases of Microsoft Windows.
