Windows Secure Boot certificate expiration

Important: Secure Boot certificates used by most Windows devices are set to expire starting in June 2026. This might affect the ability of certain personal and business devices to boot securely if not updated in time. To avoid disruption, we recommend reviewing the guidance and taking action to update certificates in advance. For details and preparation steps, see Windows Secure Boot certificate expiration and CA updates.

To learn about Windows update terminology, see the pages on types of Windows updates and monthly quality update types. For an overview, see the update history page for Windows 11, version 24H2.

Highlights​

Gradual rollout​

A gradual rollout distributes a release update over a period of time instead of all at once. This means that users receive the update at different times, and it might not be immediately available to all users.
