When the Health Key and Certificate Management Service is started, it is running as localSystem in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the Health Key and Certificate Management Service fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the hkmsvc service has failed to start.
