Event ID 12 — Automatic Root Certificates Update Configuration

Updated: November 30, 2007

Applies To: Windows Server 2008


The Automatic Root Certificates Update component is designed to automatically check the list of trusted authorities on the Microsoft Windows Update Web site. Specifically, there is a list of trusted root certification authorities (CAs) stored on the local computer. When an application is presented with a certificate issued by a CA, it will check the local copy of the trusted root CA list. If the certificate is not in the list, the Automatic Root Certificates Update component will contact the Microsoft Windows Update Web site to see if an update is available. If the CA has been added to the Microsoft list of trusted CAs, its certificate will automatically be added to the trusted certificate store on the computer.
