Microsoft released Windows 11 Insider Preview Build 26300.8170 (announced April 10, 2026), introducing enhanced Secure Boot visibility in Windows Security, refined User Account Control behavior to reduce prompt fatigue, and storage management improvements (including FAT32 formatting limit increase and performance optimizations). The build also fixes telemetry inaccuracies and improves Feedback Hub usability; these are feature and security-hardening updates deployed via Controlled Feature Rollout rather than a report of a security incident.
