A recently disclosed Linux kernel vulnerability, tracked as CVE‑2025‑40026, affects KVM's x86 virtualization paths and stems from an unsafe assumption in a fastpath used when completing userspace I/O: KVM sometimes (re)checks L1 intercept state in a context that cannot safely perform the memory...

A recently published Linux kernel fix corrects a subtle but consequential KVM SVM fastpath bug that could cause host instability when the CPU does not supply the “next RIP” value; the patch forces SVM to avoid fastpath emulation for WRMSR and HLT VM-exits when the next RIP isn’t valid and...

Hyper‑V is not included in Windows Home editions by default, but the underlying hypervisor components already exist in the OS image and can be unlocked with a careful, unsupported manual process that uses DISM to install built‑in packages — this step‑by‑step feature explains what to check, how...

A decade into the Chromebook experiment, Google’s lightweight laptops have quietly become multi‑tool machines capable of far more than a browser and a cloud‑document; today’s Chromebooks run Android apps, support a secure Linux container for desktop software, and provide several practical paths...

Apple’s latest M5 system-on-chip stunned the enthusiast community this week after a Chinese tester published a CPU-Z (ARM64) run inside a virtualized Windows 11 session that recorded a staggering single‑thread score — one that, on paper, dwarfs the top desktop chips from Intel and AMD in the...

The migration of ATM fleets from Windows 10 to Windows 11 is no longer an optional lifecycle project — it is a mission-critical program with security, compliance, and operational implications that can determine whether a deployer meets service-level targets or becomes the next outage headline...

Windows Sandbox lets you run a fresh, disposable Windows desktop inside your existing installation so you can test untrusted apps and browse risky sites without touching your main system — and enabling it in Windows 11 is usually a quick, low-friction process that pays off in safety and...

Windows 10’s official support end is a hard deadline — but for organizations wrestling with legacy, mission‑critical applications, the moment is not a verdict of doom; it’s a call to action with practical, fast, and defensible options to keep apps running securely while you plan longer‑term...

A simple three-image metaphor — a lone pickup with a crate, a convoy of trucks hauling trailers, and a single pickup stacked with multiple boxes — captures the essential differences between stand‑alone systems, virtual machines (VMs), and containers better than most dense technical diagrams...

Microsoft has drawn a line under a decade of widespread use: Windows 10 reaches end of support, leaving millions of devices exposed unless organisations act — and for many IT teams the fastest, most controllable escape hatch is virtualization. Background / Overview Windows 10 shipped in 2015 and...

I switched my usual VM workflow to Windows Sandbox for a week, ran a steady stream of third‑party apps, and came away impressed — but not uncritical — about how Microsoft’s lightweight, disposable virtualization tool changes the way enthusiasts and developers can test software on Windows...

Windows can be pushed toward “mostly immutable,” but achieving that feeling of an unbreakable PC on a consumer machine takes trade-offs, careful tooling, and a willingness to accept brittleness where convenience once lived. Background / Overview Immutability in operating systems means separating...

LockBit 5.0 has reappeared as a multi‑platform threat that researchers say can hit Windows, Linux and VMware ESXi hosts in a single campaign — and its blend of enhanced obfuscation, modular design and virtualization‑aware routines makes it a materially different threat for enterprise defenders...

Microsoft pushed an unscheduled, out‑of‑band cumulative update to Windows 11 version 24H2 to address a high‑impact compatibility regression affecting virtualized Office deployments — but the patch also reiterates a known SMBv1 connectivity caveat administrators must account for before broad...

Windows Sandbox is the kind of overlooked Windows feature that quietly solves real-world problems for developers, power users, and anyone who downloads software they don’t fully trust—without the friction of setting up a full virtual machine. Background Windows has shipped many niche features...

Windows Server 2022 Datacenter’s promise of “unlimited virtualization” is not marketing hyperbole — when properly licensed and activated with a Datacenter product key, the edition gives organisations the legal right to run an unlimited number of Windows Server virtual machines (VMs) on a...

The debate about whether Windows 10 or Windows 11 delivers the better gaming experience is no longer a purely technical argument — it has become a cultural one, tied up with benchmarking obsession, perceived differences versus measurable gains, and a growing tension between security features...

Windows 10 will stop receiving free security fixes on October 14, 2025 — and if your PC can’t take the free Windows 11 upgrade, you have five realistic paths forward: enroll in Extended Security Updates (ESU), buy or rent a new Windows 11 PC (including cloud PCs), perform an unsupported upgrade...

Microsoft’s claim that Arm-based Windows PCs now see most user minutes spent inside natively compiled apps marks a pivotal moment for the platform — a transition from compatibility-first survival to native-first performance and efficiency. Microsoft executives point to a figure that will shape...

Steam will stop supporting Windows 32‑bit installations on January 1, 2026, a move that, if confirmed and implemented as reported, will leave the vanishingly small number of users still running Windows 10 in its 32‑bit form without client updates, security fixes, or official Steam Support help —...
