About this tag
KB5077744 is a January 2026 out-of-band (OOB) emergency update from Microsoft, released on January 17, 2026, to address regressions introduced by the January 13 Patch Tuesday security rollup. Affected systems experienced Remote Desktop authentication failures, shutdown and hibernation problems, and Secure Launch issues. This update is part of a two-wave servicing cycle that also includes KB5078132 and KB5078127, released on January 24. Administrators should treat these OOB releases as normal Windows servicing events, as the traditional Patch Tuesday-only update model is no longer sufficient. The fixes are critical for maintaining remote connectivity and system stability on Windows 11 and other affected Windows families.
