Microsoft releases Windows 11 ISO file for Arm, but older PCs may require extra effort

Microsoft has taken a significant step forward by releasing a Windows 11 ISO file specifically designed for Arm-based computers. This latest version of Windows 11, set for 2024, allows users to install the operating system directly on devices such as Copilot+ PCs and other systems powered by Arm processors. While ISO files have been available for x64 CPUs for some time, this marks a notable first for Arm-based systems, which have previously only come with Windows 11 preinstalled.

Installation Options and Considerations

The ISO is accessible via a dedicated page for downloading Windows 11 for Arm-based PCs, offering various installation scenarios. Users can utilize the ISO to create a virtual machine within their existing operating system. For instance, many rely on VMWare’s Workstation Pro to set up and manage virtual environments. Alternatively, the ISO can be employed to upgrade an existing Windows installation to the latest version. The process is straightforward: download the file, mount it, and execute the setup.exe to initiate the installation.

Another practical application of the ISO file is the creation of a bootable flash drive, allowing for a clean installation of Windows 11. However, users should be aware that while newer Arm-based PCs, particularly those equipped with Snapdragon X chips, can seamlessly accept the ISO file, additional steps may be necessary post-installation. Microsoft clarifies that devices featuring the Snapdragon X Series processor can boot from the ISO without requiring extra drivers from manufacturers. Nevertheless, full functionality will only be restored once the appropriate drivers are installed.

To achieve this, users must connect to Windows Update via an ethernet connection using a dongle or dock to download the necessary drivers. After installation and rebooting the device, all subsystems should operate as intended. However, for those with older Arm-based PCs, the situation can be more complex. Microsoft warns that users may need to obtain specific drivers from their computer manufacturers to ensure the installation media is bootable.

For devices utilizing previous generations of Snapdragon processors, it is essential to inject the necessary drivers into the installation image. Failing to do so may result in boot failures or non-functional input. While the term “injecting” may evoke images of medical procedures, the actual process is relatively manageable, albeit time-consuming. Microsoft provides a support document detailing how to add the driver package to the ISO, making the task more approachable for those with a bit of technical know-how.

As Windows on Arm continues to evolve, there is hope for further enhancements from Microsoft. Users are encouraged to share their questions and feedback regarding this new option through the appropriate channels, such as GitHub or the Feedback Hub.
