Windows 11 KB5089549 & KB5087420 cumulative updates released

Microsoft released Windows 11 cumulative updates KB5089549 and KB5087420 as the May 2026 Patch Tuesday, addressing 120 security vulnerabilities and delivering bug fixes and new features (including Xbox mode, expanded archive support in File Explorer, haptic input support, and improved reliability for Windows Hello and taskbar components). The bulletin describes improvements across system components, an optional secure batch-file processing mode, and installation methods, but contains no technical indicators, exploit details, or evidence of active widespread exploitation—only a brief warning about AI-chained zero-days and potential future exploit activity.
