There are far fewer reasons to run a full Windows install on a Mac in 2025 than there were three decades ago, yet for a shrinking — still important — slice of users the question is as practical as it is technical. Mark Lyndersay’s column captures that evolution: from SoftWindows and Connectix...

Windows 11 includes a powerful, low-friction tool for vetting unknown programs: Windows Sandbox — a built‑in, disposable virtual environment that boots a clean copy of the same Windows build you run on your PC, isolates any activity from your host system, and discards everything the moment you...

Running Windows Vista on a Windows 11 PC is entirely doable today — but only as a carefully configured virtual machine (VM) or by using Windows’ compatibility layers for individual programs; installing Vista directly on modern hardware remains impractical and unsafe. Overview Windows Vista is...

If you run a home lab, enabling four specific BIOS options—CPU virtualization (VT‑x / AMD‑V), IOMMU (VT‑d / AMD‑Vi), SR‑IOV, and C‑States—will be among the most impactful firmware tweaks you can make to turn old desktops and laptops into reliable, efficient server nodes for virtualization, GPU...

The discovery that a sophisticated espionage group is running covert Linux virtual machines inside compromised Windows 10 hosts marks a notable escalation in adversary tradecraft: rather than installing traditional on‑host malware, the attackers enable Hyper‑V, import a minimal Alpine Linux VM...

A veteran tinkerer has taken Windows 7 and stripped it down to an almost absurd extreme — a bootable x86 image that reports an on-disk size of just 69.0 MB — a proof‑of‑concept that vividly demonstrates the technical boundary between what an operating system needs to boot and what it needs to be...

Enterprises and home labs alike face a deceptively simple-sounding decision: which hypervisor will reliably run the workloads you care about, at the scale you need, without breaking the bank or compromising security. This feature unpacks the practical tradeoffs—performance, availability...

A days‑long internet stunt has become a serious technical demonstration: a veteran Windows tinkerer known as Xeno released a bootable Windows 7 x86 image that measures just 69.0 MB on disk — a size so small it fits comfortably on a vintage floppy image several times over. The build boots to a...

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...
