out of band updates

Microsoft moved quickly after January Patch Tuesday to roll out emergency fixes for two disruptive regressions that began appearing on January 13, 2026 — an out‑of‑band repair that restores proper shutdown/hibernate behavior on systems with System Guard Secure Launch enabled and a companion...

Microsoft's January 2026 cumulative update for Windows 11 (KB5073455) has an unfortunate side effect on a subset of machines: systems with System Guard Secure Launch enabled may refuse to shut down or enter hibernation and will instead restart, a regression Microsoft acknowledged and corrected...

Microsoft’s January Patch Tuesday brought a familiar trade‑off: a broad security rollup that closed dozens of vulnerabilities — and, for a narrowly defined set of systems, an unexpected regression that prevents shutdown and hibernation from completing as intended. The bug, tied to the Windows 11...

Microsoft has pushed an emergency, out‑of‑band update to stop a worrying Windows 11 “restart loop” that left some machines unable to shut down or enter hibernation after January’s security rollup, and the patch also restores broken remote‑login flows that crippled Cloud PC and Azure Virtual...

Microsoft released emergency out‑of‑band updates on January 17, 2026 — most notably KB5077744 and KB5077797 — to address critical post‑Patch‑Tuesday regressions that left many users unable to sign in to Remote Desktop services or in some cases unable to shut down cleanly. The packages are...

Microsoft’s first security rollup of 2026 for Windows landed on January 13, but within days the update produced two separate, high‑impact regressions — one that prevented certain Windows 11 machines from shutting down or hibernating when System Guard Secure Launch was enabled, and another that...

Microsoft’s rapid rollback and emergency patching this month underscore a new reality for Windows administrators: even carefully staged security rollups can trigger high‑impact regressions that demand out‑of‑band intervention. Within days of Microsoft’s January 13, 2026 Patch Tuesday releases...

Microsoft shipped emergency, out‑of‑band Windows updates on January 17, 2026, after the January 13 security rollup introduced two disruptive regressions: a widespread Remote Desktop sign‑in failure affecting multiple Windows client and server lines, and a narrower shutdown/hibernation regression...

Microsoft issued targeted out‑of‑band updates on January 17, 2026 to repair two disruptive regressions introduced by the January 13 Patch Tuesday rollup: widespread Remote Desktop sign‑in failures that blocked Cloud PC and Azure Virtual Desktop access, and a configuration‑dependent bug that...

Microsoft issued emergency, out‑of‑band updates on January 17, 2026 to repair two disruptive regressions introduced by the January 13 Patch Tuesday rollup: widespread Remote Desktop credential and sign‑in failures that broke Cloud PC/AVD connections, and a configuration‑specific bug that caused...

Microsoft’s January update cycle took an unexpected detour this week when a Patch Tuesday release introduced a narrowly scoped but disruptive regression that left some Windows 11 systems unable to shut down or enter hibernation, forcing Microsoft to ship emergency out‑of‑band (OOB) updates on...

Microsoft has confirmed that its January 2026 Patch Tuesday updates for Windows 11 introduced multiple regressions and has already shipped targeted fixes to address the most disruptive problems, but mixed reports and unacknowledged reports mean administrators and power users must act carefully...

Microsoft’s interface course-corrections and a simultaneous, urgent fix cycle in its virtualization stack illustrate two recurring truths about modern Windows: the company still moves UI-first features experimentally into server builds long before desktop rollouts, and high-impact server bugs...

Microsoft pushed a set of emergency, out‑of‑band patches in May 2022 after a security hardening in the May 10 cumulative updates changed how domain controllers map client certificates to machine accounts — a change that briefly broke certificate‑based authentication for services such as Network...
