INTRODUCTION
The table that is included in this article lists the third-party commercial certification authorities (CAs) that are trusted by Microsoft. As a Microsoft Windows user, you can use the listed CAs for secure e-commerce.
MORE INFORMATION
CAs validate the identity and entitlement of an applicant. In this process, the applicant is issued a digital certificate. You can use digital certificates to prove the identity of a remote person or a remote resource.
To verify that Microsoft customers have access to trusted CAs, Microsoft uses "WebTrust for Certificate Authorities" or an equivalent third-party audit tool. Additionally, Microsoft uses other technical requirements to maintain a list of trusted CAs.

How Windows updates root certificates
Microsoft Windows XP, Microsoft Windows Server 2003, and Windows Vista are designed to automatically check the list of trusted CAs on the Microsoft Windows Update Web site. Then, Windows installs root certificates after certificates are validated by an application of the user. For more information about how Windows updates root certificates in Windows Vista, visit the following Web site:

For more information about how Windows updates root certificates in Windows Server 2003, visit the following Web site:
Note In Windows Server 2003, the issuer list cannot be greater than 0x3000. When you update root certificates, the list of trusted CAs increases sigficantly in size and may cause the list to grow too long. The list then gets truncated and may cause problems with authorization. This behavior may also cause schannel event ID 36885.
