Windows Secure Boot certificates are reaching the end of their useful life and will expire in June 2026. Microsoft has been preparing a replacement for months that it has coordinated with computer manufacturers, motherboard manufacturers and firmware vendors responsible for the Unified Extensible Firmware Interface or UEFI.
Last week, Microsoft updated the ‘Windows Security’ application to add a status indicator that will help you verify the installation of the new certificates and resolve any issues they present. Although most new computers should receive them without user intervention on devices that have automatic updates activated in Windows Update, there are other cases that will previously require BIOS updates and other prerequisites that should be known to counteract critical errors that have also been reported.
