About this tag
The Windows Security app is the central interface for monitoring Secure Boot certificate status on Windows 11 and Windows 10 PCs. Recent threads highlight that Microsoft is using the app to display clear green, yellow, or red indicators showing whether a device has the updated 2023 Secure Boot certificates or still relies on 2011-era certificates that begin expiring in June 2026. The app also surfaces alerts and guidance for users and IT teams to ensure systems remain trusted and bootable. Topics covered include the April 2026 security updates, the KB5081151 Safe OS update, and practical steps to check certificate status via the Windows Security app. The recurring theme is that the app now serves as a proactive tool for managing boot-chain trust before certificate expiration.
