system guard secure launch

Microsoft’s shutdown bug — the one that turns “Shut down” into an unintended all‑nighter — has widened its footprint: what began as a Windows 11 23H2 problem tied to System Guard Secure Launch now affects a subset of Windows 10 deployments as well. Administrators and power users discovered that...

Microsoft’s January security rollup introduced a startling regression: machines that should have powered off instead sprang back to life, and the problem has proven both widespread and stubborn — now confirmed to affect not only Windows 11 but certain Windows 10 configurations as well...

Microsoft’s vendor acknowledgment that the January security roll-up is causing some Windows 10 PCs to restart instead of shutting down marks a rare and uncomfortable convergence: an end‑of‑life OS still receiving paid security updates, and a modern, low‑level security feature colliding with...

Microsoft’s own release notes now show the shutdown-and-hibernate regression that began with January’s Patch Tuesday is not fully fixed: while Microsoft’s mid‑January out‑of‑band (OOB) update addressed many machines, a residual population of PCs — specifically those with System Guard Secure...

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...

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...

In a rare bit of good news for people who still want their Windows desktop to act like a local desktop, OneDrive’s Folder Backup (Known Folder Move) on Windows 11 has quietly gained a better undo flow — in some builds you can now stop folder backup and have OneDrive move your files back to the...

Microsoft confirmed that its January 13, 2026 cumulative update for Windows 11 — shipped as KB5073455 for version 23H2 — caused a regression on some systems with System Guard Secure Launch enabled that made the shutdown button unreliable and rendered sleep/hibernation unusable, and the vendor...

This month’s Patch Tuesday rollout for Windows 11 introduced a pair of disruptive regressions — systems that restart instead of shutting down, and Remote Desktop and Cloud PC sign in failures — forcing Microsoft to issue emergency out‑of‑band (OOB) fixes to stop the bleeding and restore business...

Microsoft’s January security rollup introduced a narrowly scoped but disruptive Windows 11 regression: after installing the January 13, 2026 cumulative update (tracked as KB5073455073455), some systems—primarily those running Windows 11, version 23H2 with System Guard Secure Launch enabled—would...

Microsoft’s January Patch Tuesday hiccup that left some Windows 11 PCs refusing to power off has laid bare a deeper tension: the company’s aggressive pivot to AI-first features is colliding with the chores of patching, firmware hardening, and the bedrock expectation that a computer will actually...

Microsoft’s January cumulative update briefly turned into an openrational emergency for a narrow—but impactful—slice of Windows 11 users when some machines refused to remain powered off, prompting Microsoft to publish an interim workaround and ship an out‑of‑band remedial update days later. The...

Microsoft’s first Windows 11 update of 2026 disrupted shutdown behavior on a narrow but important slice of devices and forced an out‑of‑band emergency fix hours later; the January 13 Patch Tuesday cumulative (notably KB5073455 for Windows 11 23H2) introduced a configuration‑dependent regression...

Microsoft released its January 13, 2026 security rollup for Windows 11 and within days administrators and users began reporting a troubling side effect: on a narrow but consequential set of machines the system would refuse to power off or enter hibernation, instead immediately restarting after a...

Microsoft’s first Windows 11 security rollup of 2026 delivered a routine library of fixes — and, for a narrow but important subset of devices, it broke the most basic user expectation: the ability to shut down cleanly. Within days of Patch Tuesday (January 13, 2026) reports surfaced that some...

Microsoft pushed emergency out‑of‑band updates on January 17, 2026 to repair two high‑impact regressions introduced by the January 13 Patch Tuesday rollup: one that prevented some Windows 11 systems with System Guard Secure Launch enabled from shutting down or hibernating, and another that broke...

Microsoft’s first Patch Tuesday of 2026 left an unexpected wake: a narrowly scoped but disruptive bug in the January cumulative updates prevented some Windows 11 devices from shutting down or entering hibernation, prompting urgent out‑of‑band patches and a fast-moving crisis-management effort...

Microsoft moved fast this week to contain a disruptive Windows 11 reliability regression: an urgent, out‑of‑band patch labeled KB5077797 was published on January 17, 2026 to repair a shutdown/hibernate regression and related Remote Desktop authentication failures introduced by January’s Patch...

Microsoft’s first Windows 11 security rollup of 2026 produced a narrowly scoped but operationally painful regression: after installing the January updates some devices — primarily Windows 11, version 23H2 systems with System Guard Secure Launch enabled — restarted instead of powering off or...

Microsoft’s January Patch Tuesday produced more than the usual mix of security fixes: for a narrow but important slice of Windows 11 deployments the update briefly prevented systems from shutting down or entering hibernation, triggered remote-desktop authentication failures for some clients, and...
