Microsoft is rolling out new Secure Boot certificates through Windows updates to replace the original ones expiring in June 2026. This update enhances security by ensuring that only trusted software can load during startup. Devices on unsupported Windows versions won’t receive these updates and will enter a "degraded security state."

Microsoft has resolved a boot issue affecting Linux on dual-boot systems with Secure Boot enabled after the August 2024 Windows security updates. The problem stemmed from an incorrectly applied Secure Boot Advanced Targeting update, which has now been fixed in the May 2025 Patch Tuesday updates. Users are advised to update their devices to incorporate this resolution.
