Your Windows PC is at risk if you're missing these security certificates

PCWorld reports that Windows PCs need updated 2023 Secure Boot certificates as older 2011 certificates expire in 2026, leaving systems vulnerable to malware. Hardware vendors, not Microsoft, control these critical security updates through UEFI/BIOS firmware, meaning unsupported older PCs may require hardware upgrades. Users can check their protection status in Windows Security app for a green Secure Boot checkmark and update firmware accordingly. You've probably seen countless warnings lately about Windows and expiring Secure Boot certificates . Why? Some PCs haven't gotten the updates yet--and won't unless you take action.
