Developed and released the initial High Confidence Buckets dataset for Secure Boot DB and KEK 2023 certificate rollout in the microsoft/secureboot_objects repository. The work involved data engineering and analysis to construct device buckets using SMBIOS identifiers, with criteria for high confidence derived from telemetry. Delivered the dataset in CSV format, accompanied by comprehensive documentation detailing data derivation, schema, and quality considerations. Provided clear guidance for administrators, OEMs, and non-Windows platforms to support phased, auditable certificate updates and partner replication. Focused on release quality, the work emphasized robust documentation and data structure to minimize rollout risk and support ecosystem adoption.
