out of band fixes

About this tag
Out of band fixes are emergency updates released by Microsoft outside the regular Patch Tuesday schedule to address critical regressions or security issues. In January 2026, Microsoft issued multiple out of band fixes after the cumulative update KB5074109 caused boot failures, Remote Desktop sign-in problems, Secure Launch shutdown/hibernate failures, and app crashes. These out of band fixes, including KB5077797 and KB5077744, were published on January 17, 2026 to restore system stability and functionality. Administrators and users should apply these out of band fixes through Windows Update or the Microsoft Update Catalog if affected.
