Microsoft is rolling new 2023-dated Secure Boot certificates to replace expiring 2011 certificates in June 2026; while most systems will update automatically via Windows Update, older or misconfigured devices may not transition cleanly and could miss future boot-level protections. The article explains the staged rollout, potential failure modes (outdated firmware, disabled Secure Boot, legacy BIOS, custom firmware), cites the BlackLotus UEFI bootkit as a concrete threat example, and provides guidance for home users and IT teams to inventory devices, check Secure Boot status, and apply firmware and Windows updates.
