high confidence database

The high confidence database is a Microsoft-managed data-driven system that determines which Windows devices are eligible for automated Secure Boot certificate updates. By analyzing device-class attributes and telemetry, the high confidence database enables a phased, risk-based rollout of certificate rotations, ensuring only systems with a high probability of successful update receive them automatically. This approach helps administrators understand why some devices get updates while others require manual intervention, reducing the chance of boot failures during large-scale Secure Boot certificate changes. The high confidence database represents a shift toward more intelligent, telemetry-informed update management in Windows.
