Secure Boot Certificate Expiry (Windows & Linux)

Описание: Secure Boot certificates on most computers expire in June and October 2026, affecting Windows 11, Windows 10 and Linux systems with secure boot activated. This video explains what is happening, the implications, and what you may potentially need to do. But do not panic! Most systems should update automatically, and even if they don’t, should continue to boot.
