Microsoft released the optional cumulative update KB5083631 for Windows 11 24H2 and 25H2, introducing 34 non-security changes including performance improvements, a new Xbox mode, enhanced batch file security, and Secure Boot certificate updates. The update does not include security fixes and targets quality improvements for admins to test before next Patch Tuesday. Key technical changes include a new Xbox full-screen gaming interface, stricter batch file processing mode, improved Kerberos authentication for RDP with Remote Credential Guard, and expanded Secure Boot certificate coverage with phased rollout. The update also addresses Secure Boot certificate expirations in June 2026 and introduces haptic feedback support for input devices.
