Windows updated Secure Boot just in time. Here's what happened

PCWorld 

PCWorld reports Microsoft released the Secure Boot 2023 certificate update for Windows 10 and 11 just before original 2011 certificates expired in 2026. This critical security update prevents potential PC boot issues and maintains protection against rootkits and bootkits at startup. Users can verify their certificate status through Windows Settings, with green indicating success and red requiring BIOS updates from manufacturers. Microsoft just pushed the Secure Boot 2023 certificate update to all eligible Windows 11 and Windows 10 computers, just in time given that old certificates were due to expire today . It's a good thing, too, since your PC could face real problems without updated certificates .
