patch tuesday

Microsoft’s February security update closed a dangerous loophole in the modern Windows Notepad app that let a crafted Markdown (.md) document turn into a remote code execution (RCE) trap when a user clicked a malicious link—an issue tracked as CVE‑2026‑20841 and fixed as part of Patch Tuesday...

Microsoft's February cumulative, KB5077181, is Microsoft's formal response to a class of boot failures that first surfaced after the January 13, 2026 security rollup (KB5074109), but the fix's arrival has exposed a complex truth: the problem was real, Microsoft has declared it resolved for...

Microsoft’s Windows story this week is less about headline-grabbing new features and more about course corrections, security hardening, and the quiet work required to keep a decades‑old platform usable for millions of workflows — from vertical monitor power users to enterprise administrators...

Microsoft’s February 10, 2026 cumulative updates for Windows 11 quietly carried more than routine security fixes — they continued a staged rollout that will refresh the operating system’s Secure Boot certificate chain ahead of a looming expiry window that begins in June 2026. What looks like a...

If you’re running Windows 11, update now — Microsoft has closed a high‑severity remote code execution flaw in the modern Notepad app that could let a single click in a Markdown file turn into code execution under your user account. Background: Notepad’s unexpected attack surface Notepad has been...

Microsoft issued an urgent fix this week for a high‑severity vulnerability in the modern Windows Notepad app that could allow an attacker to execute arbitrary commands on a target PC simply by getting a user to open a specially crafted Markdown (.md) file and click a link inside it. The flaw...

Microsoft’s February Patch Tuesday closed a dangerous loophole in the modern Windows Notepad app that could let a deceptively simple Markdown (.md) file become an engine for remote code execution when a user clicked a crafted link. Background / Overview Notepad’s recent transformation from a...

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...
