patch tuesday

Microsoft’s February Patch Tuesday closed a dangerous loophole in the modern Notepad app that could let an attacker turn a simple Markdown (.md) file into a remote code execution (RCE) trap — a single click on a crafted link inside Notepad’s Markdown view could launch unverified protocols and...

Microsoft’s February 2026 Patch Tuesday for Windows 11 arrived as a workmanlike but meaningful quality release: KB5077181 (OS Build 26200.7840 / 26100.7840) stitches together months of Release Preview testing, restores several long‑requested controls, modernizes niche platform stacks (notably...

A widely deployed January servicing update has created a surprising reliability problem: some Windows PCs now refuse to power off cleanly, instead restarting, hanging on “Shutting down,” or powering back on after appearing to shut down — and the same regression that showed up first on Windows 11...

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 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 moved quickly to contain a damaging January 2026 update cycle that introduced multiple high‑impact regressions across Windows 11 branches, shipping targeted out‑of‑band (OOB) fixes within days and publicly committing engineering resources to a reliability‑first posture aimed at...

Microsoft’s Patch Tuesday started 2026 with a jolt: a January 13 cumulative rollup intended to close security holes instead produced a cascade of regressions that forced Microsoft into an unusually busy sequence of emergency, out‑of‑band (OOB) updates — and left administrators asking whether...

Microsoft has pushed KB5074105 to the Windows Insider Release Preview channel, delivering builds 26100.7701 and 26200.7701 with a mix of targeted bug fixes, accessibility and creator-focused upgrades, and a handful of system‑level security and deployment changes that administrators and...

Microsoft was forced into a rare series of out‑of‑band emergency patches after January’s security rollup triggered system crashes, boot failures, and application regressions that left both home users and enterprises scrambling for fixes and workarounds. Background What happened, in plain terms...

Microsoft’s pledge to make 2026 the year Windows 11 stops being a trial-by-fire moment is welcome — but after January’s Patch Tuesday meltdown, words won’t be enough. The operating system needs stable, well‑tested updates that restore confidence for everyday users and IT pros alike. February’s...

Microsoft’s ecosystem found itself in unusually turbulent territory this week: the Windows Insider program was reshuffled, Patch Tuesday went sideways and generated multiple emergency fixes, Microsoft unveiled a new in‑house AI accelerator, major AI platforms doubled down on “apps” inside...

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...

Outlook crashing on Windows 11 after January’s Patch Tuesday left inboxes frozen, mailboxes mismatched, and IT teams scrambling — and Microsoft’s emergency out-of-band update finally appears to have stopped the worst of it. The fix targets a flaw introduced by the January 13, 2026 security...

Microsoft's January Patch Tuesday created more work for IT teams than it solved: within days of the January 13, 2026 cumulative update, users and administrators began reporting that Outlook — particularly classic Win32 profiles using local PST files stored in cloud‑synced folders — would hang...

Microsoft’s January Patch Tuesday for Windows 11 has spiraled from an awkward rollout into a painful disruption for a subset of PCs: the cumulative update KB5074109 is now being linked to full boot failures that surface as the UNMOUNTABLE_BOOT_VOLUME stop code, leaving some machines unable to...

Microsoft has confirmed that its January cumulative update for Windows 11 is linked to a small but serious class of failures that can leave some physical PCs unbootable—often with the UNMOUNTABLE_BOOT_VOLUME stop code—forcing recovery via WinRE or, in worst cases, a clean reinstall. Background...

Microsoft pushed an emergency out‑of‑band update late last week to repair a regression introduced by its January security rollup that left Outlook and other programs unable to open or save files stored in cloud‑backed folders such as OneDrive and Dropbox. The fix — delivered as KB5078127 for...

Microsoft’s January Windows 11 cumulative security update has produced a worst‑case outcome for a small but painful subset of PCs: after installing KB5074109 (the January 13, 2026 LCU/SSU bundle), some physical machines fail to complete startup, showing the UNMOUNTABLE_BOOT_VOLUME stop code and...

Microsoft’s mid‑January cumulative update for Windows 11 triggered a chain of regressions that left the classic Win32 Outlook client hanging, losing sent items, and in some cases redownloading messages — and Microsoft responded with a rapid sequence of out‑of‑band emergency updates that restored...
