Download Windows 11 25H2 ISO for ARM64 and Copilot+ PCs: Step-by-Step Guide

To access the official ISO file for Windows 11 25H2 designed specifically for arm64 architecture, visit the Microsoft download page, choose the “Windows 11 (multi-edition ISO for Arm64)” option, then confirm your language selection and click on “Download.”
Alternatively, you can employ the UUP Dump script to retrieve the installation files and create a personalized ISO file suitable for use with the Rufus tool, enabling the creation of a bootable USB installer.

UPDATE 10/3/2025: If you own an ARM-based computer (such as a Copilot+ PC powered by a Qualcomm Snapdragon X Elite processor, Surface Pro (11th Edition), or Laptop (7th Edition)), you can download the Windows 11 25H2 ISO file to carry out a clean installation of the operating system or set up a virtual machine on compatible hardware.

In my quest to find the Windows 11 ISO file for a virtual machine setup on my Apple MacBook Air, I discovered that the standard image was incompatible due to different processor architecture. Fortunately, Microsoft has now made available the Windows 11 ISO for arm64 devices, freely downloadable from the official site. You can also obtain the image using UUP Dump scripts.

The UUP Dump tool is an efficient resource that allows users to generate customized ISO images for various Windows versions, including Windows 10 and 11, for both x64 and arm64 architectures. It utilizes the Unified Update Platform (UUP) to directly fetch the necessary files from Microsoft’s servers, simplifying the process to acquire the latest builds.

It is possible to download the ISO file using an x64 (AMD or Intel) computer and subsequently create USB bootable media for arm64 machines. However, keep in mind that the arm64 ISO cannot be utilized for setting up a virtual machine or installing an operating system on devices featuring x64 processors.
