Windows 11’s new Smart App Control has just collided with the fragile integration that makes the Xbox Ally and ROG Ally feel like polished handhelds: users report Armoury Crate SE refusing to launch, background services being blocked, and firmware/update flows interrupted — and the immediate...

Microsoft's latest push to harden Windows touches nearly every layer of the platform — from how admin privileges are handled to how drives are encrypted and how devices recover after failures — and IT administrators must prepare now or risk disruption when these changes reach their production...

Microsoft has begun a coordinated, multi-year hardening of Windows that moves long-standing behaviors—particularly around Kerberos/PAC validation, Netlogon, and Secure Boot certificates—into a stricter, enforcement-first posture, and IT teams must act now to avoid authentication outages, boot...

KissCartoon and its dozens of look‑alike domains still show up in search results, but the idea of a safe, official "KissCartoon Unlimited for Windows 10" app is a myth you should not trust—what you’re likely seeing online are clone sites, APK bundles, or thin wrappers that repurpose a web page...

When something on a Windows PC “feels off” — a persistent CPU spike, a process that keeps reappearing after you remove it, or a program quietly making outbound connections — Task Manager can leave you guessing. That’s why advanced users and incident responders reach for the Windows Sysinternals...

Microsoft’s attempt to finally turn User Account Control into a real security boundary nearly unraveled before many users even saw the new design: Google Project Zero’s James Forshaw documented nine distinct bypasses against Windows 11’s new Administrator Protection during its insider-preview...

Microsoft’s attempt to make privilege elevation in Windows 11 a true security boundary ran into a harsh reality check: decades of legacy kernel behavior are hard to rewrite safely. Google Project Zero’s James Forshaw exposed multiple privilege‑escalation bypasses against the new Administrator...

Microsoft’s security tooling has once again collided with real‑world device workflows — this time stomping on the Xbox‑focused handheld experience and leaving owners unable to update or run critical OEM tools. Reported incidents show Windows’ application control layer blocking components of...

Security researchers have shown that a single, seemingly legitimate Copilot link could be turned into a stealthy data‑exfiltration pipeline — an attack chain the research community has labeled “Reprompt” — and the discovery raises urgent questions for anyone who uses Microsoft Copilot Personal...

Google Project Zero’s James Forshaw has pulled back the curtain on a subtle, multistage weakness that could have let attackers sidestep Microsoft’s new Administrator Protection model and silently obtain administrator privileges — and the discovery exposes how decades-old Windows behaviors can...

A newly published security advisory from iba Systems warns that a flaw in ibaPDA could allow unauthorized actions on the file system under certain conditions — a risk that can affect confidentiality, integrity, and availability of managed measurement and acquisition data. The vendor’s fix is...

A massive, unsecured database containing roughly 149 million unique usernames and passwords — an estimated 96 GB of raw data — was discovered and reported this month by security researcher Jeremiah Fowler, and the fallout should be a wake-up call for every Windows user and administrator who...

If you’re about to hand off, sell, donate or recycle a Windows PC, the right way to wipe it matters — not just to protect your privacy, but to avoid hours of post‑sale headaches for the next user. The sensible playbook is simple: migrate what you need, make personal data irrecoverable, and...

Windows' built-in protection has come a long way — for many everyday users, Microsoft Defender (Windows Security) now provides a very credible baseline of protection, but whether you can safely rely on it alone depends entirely on what you do online, whose data you protect, and how disciplined...

Secure Windows 10/11: Turn On Core Isolation (Memory Integrity) + Fix Driver Blocks Difficulty: Intermediate | Time Required: 15 minutes Core Isolation’s Memory integrity feature (also called HVCI – Hypervisor-Protected Code Integrity) adds an extra security layer that helps prevent malicious or...

Fast Startup is designed to shave seconds off cold boots by saving a partial OS state to disk, but because it deliberately preserves kernel and driver state between shutdowns it can also hide faults, block other operating systems from safely accessing Windows volumes, and interfere with certain...

Johnson Controls’ iSTAR Configuration Utility (ICU) tool has a newly disclosed vulnerability — a stack‑based buffer overflow assigned CVE‑2025‑26386 — that can crash the Windows host running the utility and, in certain conditions, enable more severe host‑impact outcomes if exploited. The...

Microsoft’s January Patch Tuesday includes a high-priority update that refreshes expiring Secure Boot certificates on Windows devices — a preventative, must-install fix that closes a narrow but critical window attackers could use to install persistent bootkits before the OS loads. rview UEFI...

Microsoft has begun a staged hardening of Kerberos on Windows domain controllers: starting with security updates released on January 13, 2026, domain controllers will gain new telemetry and audit controls that identify weak Kerberos encryption usage, and Microsoft plans a phased default flip so...
