What happened
Microsoft's Secure Boot signing certificate (used to validate Windows bootloaders/drivers and also used by some Linux distributions) expires today. The lapse can affect secure-boot validation on over a billion PCs and may cause update or boot/driver verification problems unless systems receive the updated signing/certificate revocation info (via Windows Update, firmware/UEFI updates, or vendor guidance). Users should check for and apply official Secure Boot/certificate updates from Microsoft and their PC/firmware vendor to avoid disruptions.
