secure launch

A widely distributed January 2026 security update left a slice of Windows PCs unable to power off cleanly: hitting the shutdown button causes some machines to restart, and in other cases the system refuses to hibernate. Microsoft acknowledged the problem, released emergency out‑of‑band patches...

Microsoft’s January update headache widened again this month: a restart-on-shutdown regression that began with the January 13, 2026 cumulative updates and was initially tied to System Guard Secure Launch on Windows 11 has now been confirmed to affect some Windows 10 systems with Virtual Secure...

Microsoft has confirmed that its January 13, 2026 security rollup for Windows — published as KB5073455 for Windows 11 version 23H2 — introduced a configuration-dependent regression that can leave some systems unable to shut down or enter hibernation. Affected machines with System Guard Secure...

Microsoft has expanded its acknowledgment of a Windows 11 shutdown regression first reported in mid‑January, confirming that the January 13, 2026 cumulative update (KB5073455) can cause some PCs configured with System Guard Secure Launch (Virtual Secure Mode / VSM) to restart instead of powering...

Microsoft’s January update mess has proven more stubborn than first advertised: the shutdown and hibernation regression that surfaced after the January 13, 2026 cumulative updates is still troubling a subset of Windows installations, and Microsoft’s own release notes now acknowledge the problem...

Microsoft’s shutdown bug is no longer a narrow oddity hiding in enterprise telemetry — it’s a demonstrable, multi‑stage reliability failure that touched a surprising range of Windows configurations and forced emergency patches, workarounds, and hard operational choices for IT teams and power...

Microsoft’s latest admission that the January hibernation fix still isn’t universal turns what began as a narrow, configuration‑dependent regression into a broader reliability headache for enterprises and device makers alike. On January 30 Microsoft updated its Release Health dashboard to...

Microsoft has confirmed that the shutdown-and-hibernation regression triggered by January’s Patch Tuesday affects a broader set of enterprise-grade configurations than originally disclosed: an out-of-band fix addressed many Secure Launch cases, but systems using Virtual Secure Mode (VSM) remain...

Microsoft has confirmed that January’s Patch Tuesday updates introduced a regression that can leave some Windows 11 PCs unable to shut down or enter hibernation — affected systems instead restart — and the company shipped an out‑of‑band (OOB) cumulative update to address the problem within days...

Windows 11 users and administrators woke up in mid‑January to a puzzling and disruptive problem: after applying Microsoft’s January cumulative update some PCs refused to power off cleanly. Instead of shutting down or reliably entering hibernation, affected systems often restarted or remained...

Microsoft’s January update roll-out has already cost IT teams a sleepless weekend and forced two emergency fixes inside a single fortnight — a chaotic start to Windows 11 patching in 2026 that raises fresh questions about testing, packaging, and communication for Microsoft’s flagship desktop OS...

Microsoft shipped emergency out‑of‑band updates this month to correct two disruptive regressions introduced by January’s cumulative rollup: a configuration‑specific shutdown/hibernate failure tied to System Guard Secure Launch, and separate Remote Desktop authentication failures. Microsoft’s...

Microsoft shipped its first major Windows patches of 2026 with a list of fixes and security updates — and within days had to ship emergency patches to undo some of its own work after users reported shutdown failures, remote‑desktop authentication breaks, Outlook hangs and intermittent black...

A routine Windows security update should not leave machines refusing to power off. Yet in mid‑January a cumulative package for Windows 11 created a nasty, configuration‑dependent bug: on some systems the Shutdown and Hibernate commands were ignored and the PC simply restarted. That regression...

Microsoft’s January cumulative updates for Windows 11—delivered as KB5074109 (for 24H2/25H2) and the sibling KB5073455 for 23H2—introduced important security and reliability fixes but also produced a string of regressions that left some PCs unable to sleep, hibernate or shut down correctly and...

Microsoft has issued an out‑of‑band fix after a January update left a small subset of Windows 11 systems unable to shut down or enter hibernation — affected machines would restart instead of powering off — and the remedial package, KB5077797, is now available from Microsoft (and the Microsoft...

Microsoft has issued emergency, out‑of‑band Windows updates to fix two functional regressions introduced by its January 2026 Patch Tuesday rollup — one that breaks Remote Desktop sign‑ins in certain cloud and remote‑session scenarios, and another that causes some Windows 11 systems with System...

Microsoft’s January security rollup introduced urgent reliability problems that forced the company to ship emergency, out‑of‑band (OOB) patches days later — fixes you should install now if your device shows the symptoms described below. Background / Overview Microsoft’s regular Patch Tuesday for...

Microsoft has issued emergency, out‑of‑band (OOB) Windows updates to correct two disruptive regressions introduced by the January 2026 Patch Tuesday rollout: a Remote Desktop sign‑in failure that broke credential prompts for some modern remote clients, and a shutdown/hibernate regression that...

Microsoft has quietly pushed emergency, out‑of‑band (OOB) Windows updates after its January Patch Tuesday rollup introduced two separate, operationally serious regressions: a Remote Desktop/Cloud PC sign‑in failure across multiple servicing branches, and a Secure Launch–linked shutdown/hibernate...
