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 leaders no longer dispute that Windows 11 has serious, real-world reliability problems — the company has publicly acknowledged the fallout from January’s updates, called engineers back from feature work to “swarm” on fixes, and has begun shipping emergency out‑of‑band patches to stem...
Microsoft’s public admission that Windows 11 needs repair and the company’s pledge to “swarm” engineers onto the problem marks a dramatic shift in priorities: 2026 will be the year Microsoft says it will put reliability, performance, and everyday user experience ahead of headline features...
Microsoft’s public concession that Windows 11 has slid past “annoying” into a systemic quality problem is the most consequential signal yet: engineers are being redirected into tactical “swarming” teams to triage a wave of regressions that culminated in emergency out‑of‑band patches and, for a...

Microsoft released its January cumulative for Windows 11 (KB5074109) on January 13, 2026 — and within days a series of serious regressions began surfacing, from brief black screens on some Nvidia-equipped machines to full startup failures that print UNMOUNTABLE_BOOT_VOLUME (Stop Code 0xED) and...
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 moved quickly to contain a trio of disruptive regressions introduced by the Windows 11 January 2026 Patch Tuesday wave, shipping targeted out‑of‑band (OOB) updates that restored Remote Desktop sign‑in flows and fixed a configuration‑dependent shutdown/hibernate bug — while a separate...
MicMicrosoftt shipped an emergency out‑of‑band update this week to repair credential prompt and authentication failures that blocked Azure Virtual Desktop (AVD) and Windows 365 connections after its January 13, 2026 Patch Tuesday rollup — a fast, narrowly scoped remediation that restores...
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 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 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...
