Another reliable method involves using UUPdump (uupdump.net) to generate a Windows 10 ARM ISO from official Microsoft update files. After downloading the scripts, run uup_download_windows.cmd and let it complete — the process will generate a usable ISO file.
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.

Unlike standard x86 Windows, Microsoft does not provide a direct retail ISO for Windows 10 on ARM.

This guide explores the best practices for setting up, managing, and optimizing a Windows 10 ARM64 qcow2 virtual machine. What is qcow2 and Why Use it for Windows 10 ARM?
A raw QCOW2 is fine, but an optimised one is transformative.
