In a significant development for the Windows on Arm ecosystem, Microsoft has officially released Windows 11 Arm64 ISO files, enabling users to perform clean installations on Arm-based PCs. This move addresses a longstanding gap in support for Arm64 devices, providing a streamlined method for setting up Windows 11 on compatible hardware.

Background and Context

Historically, Windows on Arm has faced challenges in terms of installation and compatibility. Prior to this release, obtaining official installation media for Arm-based devices was cumbersome, often requiring users to rely on third-party tools or unofficial methods. The availability of official Arm64 ISOs marks a pivotal moment in Microsoft's commitment to the Arm architecture, aligning with the growing adoption of Arm-based devices in the consumer and enterprise markets.

Technical Details

The released ISO files are designed for Arm64 architecture, corresponding to the Windows 11 24H2 release. Users can download these ISOs directly from Microsoft's official website. The ISOs are approximately 5GB in size, depending on the selected language. While primarily intended for creating virtual machines, Microsoft indicates that these ISOs can also be used for clean installations on Arm64 hardware. (windowscentral.com)

Installation Considerations

For devices equipped with Snapdragon X Series processors, the ISO should boot without additional drivers. However, for older Snapdragon models, users may need to integrate specific drivers from the device manufacturer into the ISO image to ensure successful booting and functionality. This process involves extracting the necessary drivers and incorporating them into the installation media, a step that may require technical expertise. (learn.microsoft.com)
