secure launch

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 moved quickly after its January Patch Tuesday to publish an emergency out‑of‑band (OOB) Windows update on January 17, 2026 that fixes two high‑impact regressions introduced by the January 13 security rollup: a configuration‑dependent shutdown/hibernation failure on certain Windows 11...

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 issued an unscheduled, out‑of‑band Windows update after January’s Patch Tuesday created two disruptive regressions—broken Remote Desktop authentication across multiple client and server lines, and a Secure Launch–linked shutdown/hibernate regression on Windows 11 23H2—forcing a rapid...

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 has confirmed a narrow but disruptive regression in its January 13, 2026 cumulative update for Windows 11, version 23H2 (KB5073455): on devices where System Guard Secure Launch is enabled, choosing Shut down or attempting Hibernate can cause the machine to restart instead of powering...

Microsoft pushed an emergency out‑of‑band Windows update after a wave of post‑Patch Tuesday reports left some PCs restarting when they should shut down, failing to hibernate reliably, and — in a separate but equally disruptive fault — blocking Remote Desktop sign‑ins that underpin much remote...

Microsoft moved quickly after January’s Patch Tuesday to issue emergency fixes for multiple Windows 11 regressions that left some users unable to sign in to Remote Desktop sessions and others unable to shut down cleanly. The out‑of‑band updates—published on January 17, 2026 as KB5077744 and...

Microsoft released a series of targeted out‑of‑band (OOB) patches on January 17, 2026 to repair failures introduced by the January Patch Tuesday security rollup—most notably Remote Desktop sign‑in failures and a Secure Launch shutdown/hibernation regression on some Windows 11 devices. The fixes...

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 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 pushed emergency fixes the week after January’s Patch Tuesday to neutralize two high‑impact regressions that left some Windows 11 PCs either unable to shut down cleanly or unable to authenticate into Remote Desktop sessions, and it also acknowledged a separate Outlook Classic...

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...

A widely deployed January cumulative update for Windows 11 23H2 briefly broke the expected behavior of shutting down and hibernating on a narrowly defined set of machines, causing affected systems to reboot instead of powering off — Microsoft confirmed the regression, published an emergency...

Microsoft’s January cumulative update for Windows 11 has produced a narrow but disruptive regression: on some systems configured with System Guard Secure Launch, choosing Shut down or attempting Hibernate can cause the machine to restart instead of powering off, and Microsoft has published...

Microsoft’s January Patch Tuesday produced a narrowly scoped but disruptive problem: after installing the January 13, 2026 cumulative update (KB5073455) some Windows 11 systems configured with System Guard Secure Launch restarted instead of shutting down or entering hibernation, forcing...

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...
