Create a new text file named win10arm64.bat (for Windows) or win10arm64.sh (for Linux/macOS). This script will contain the QEMU command to launch your VM. A script simplifies the process, allowing you to tweak parameters without retyping the entire command each time.
If you have downloaded a Windows 10 ARM "Insider Preview" VHDX from the Microsoft Windows Insider Program , use the qemu-img tool to convert it:
Combining them allows you to run high-performance Windows environments on Linux ARM64 hosts or Apple Silicon using hypervisors like QEMU, UTM, or Proxmox VE. 2. How to Obtain a Windows 10 ARM QCOW2 Image
Unpack the archive and run the script ( uup_download_linux.sh or uup_download_windows.cmd ). windows 10 arm qcow2
-M virt,highmem=on : Specifies the generic ARM64 virtual machine board type.
In this guide, we'll walk you through the process of creating a Windows 10 on ARM virtual machine using QEMU and QCOW2.
This creates a disk that can grow up to 40GB but starts at only a few megabytes. Create a new text file named win10arm64
| Feature | Status | Notes | |--------|--------|-------| | Boot time | ✅ Fast (10-15s) | NVMe/virtio-block | | Graphics | ⚠️ Basic | No 3D acceleration in Win10 ARM | | x86 emulation | ✅ Works | Windows 10 ARM runs 32-bit x86 apps | | Network | ✅ VirtIO | User-mode NAT works | | Clipboard sharing | ✅ SPICE | Enable SPICE agent in guest |
: When prompted, choose "Custom: Install Windows only (advanced)".
While Windows 10 ARM remains a niche environment, the arrival of Windows 11 ARM has improved x64 (64-bit) emulation significantly. As tools like UUP Dump make creating ARM ISOs easier, the QCOW2 format remains the most efficient way to experiment with Windows on ARM hardware. It offers a lightweight, snapshot-friendly bridge between the Linux host environment and the Windows ecosystem. If you have downloaded a Windows 10 ARM
QEMU (Quick Emulator) is an open-source machine emulator and virtualizer capable of running operating systems for various target architectures. The QCOW2 (QEMU Copy On Write version 2) format is QEMU's native disk image format with powerful features that make virtualization more efficient and flexible.
As the computing landscape shifts toward ARM architecture—powered by devices like the Raspberry Pi, Qualcomm Snapdragon Dev Kits, and Apple Silicon—the need for versatile virtualization solutions has never been higher. For developers and power users running Linux on these machines, the QCOW2 (QEMU Copy On Write) format has become the gold standard for managing virtual disk images.
Here is how to convert and prepare it for QEMU/KVM environments. Step 1: Obtain the Windows 10 ARM Base File To get the official image: Navigate to the page.

Running Windows 10 on ARM via QCOW2: The Ultimate Guide Windows 10 on ARM has emerged as a powerful solution for developers, sysadmins, and enthusiasts who need to run Windows applications on non-x86 hardware. Whether you are using an Apple Silicon Mac, an ARM64 cloud server, or a Raspberry Pi, virtualization is often the most efficient route. At the heart of modern open-source virtualization (like QEMU and KVM) sits the (QEMU Copy-On-Write) disk image format.
