You may not be aware, but there’s an impending deadline for Windows Secure Boot. Come June 2026, and you and your Windows PCs could be affected by this potential issue. When configured, Secure Boot verifies the system before Windows even boots, making full use of cryptographic certificates, and this is what is set to expire later this year. Devices without updated certificates lose access to new Secure Boot protections and updates, but continue booting Windows normally.
