Last Updated: October 2014

This is the temporary landing page for the list of Certification Authorities (CAs) who are members of the Windows Root Certificate Program.  Beginning with the release of Windows Phone 8, the management of root certificates from member CAs is done by a single Program which manages the distribution of root certificates for CAs across desktop Windows and Windows Phone 8 devices.

The list of Certification Authorities (CAs) who are members of the Windows Root Certificate Program as of September 2014 is available as a PDF document.

Please note, the old landing page for member CAs is no longer maintained, however all information has been verified and in some instances corrected, and appears on this page.  Also - this landing page will soon be replaced with a link to the Microsoft Download Center, where a file will be available with additional details on member CAs and the root certificates we distribute in the Program.  Please stay tuned...
