Microsoft is urging IT and security leaders to update the Secure Boot certificates on all Windows PCs made before 2024. The original Unified Extensible Firmware Interface (UEFI) Secure Boot certificates will start expiring on June 24. Secure Boot is a feature that checks that only properly signed and approved firmware is loaded at startup. PCs designed for Windows 10 and Windows 11 include Secure Boot support, but older systems may still be using the original 2011 certificates. The new 2023 certificates improve the root of trust and provide better security. Microsoft recommends prioritizing the update to ensure systems remain protected and continue receiving security enhancements.
