For app developers, IT professionals, and others who require testing across various Windows versions, the recent developments present a unique challenge. The introduction of a new Windows version tailored exclusively for the latest Arm PCs creates a transitional phase where users must navigate between this new iteration and the existing version that remains applicable to the broader user base.
Special treatment for Arm PCs
The launch of a Windows version specifically designed for new Arm PCs underscores Microsoft’s ongoing dedication to Arm processors and the Arm variant of its operating system. This marks a significant shift from the company’s historical emphasis on the x86 version, which has predominantly operated on Intel and AMD hardware.
With the release of both Windows 10 and Windows 11 in x86 and Arm editions, the 24H2 update stands out as a pivotal moment for Arm PCs. This update introduced substantial enhancements to the underlying architecture of Windows, including improvements to the compiler, kernel, and scheduler. Notably, it also featured an optimized x86-to-Arm translation layer known as Prism, which significantly bolstered the compatibility and performance of applications not originally designed for Arm processors.
The timing of the 24H2 update coincided with the debut of Qualcomm’s first-generation Snapdragon X-series processors. These high-performance Arm chips were developed by some of the same engineers responsible for Apple’s M-series chips used in Macs. This synergy has led to a wave of third-party developers finally releasing Arm-native versions of their Windows applications, which offer enhanced speed and responsiveness compared to their x86 counterparts.
Microsoft’s confidence in the Arm version of Windows is evident in its recent hardware strategy. The new Surface PCs launched in mid-2024 exclusively utilize Qualcomm processors, marking a departure from the past when Intel chips were the standard for Surface devices. Previously, Microsoft had positioned Intel- and AMD-based Surfaces as the primary offerings, while the Arm-based Surface Pro X was viewed as a secondary option.
Since the rollout of the 24H2 update, development on the Arm and traditional x86 versions of Windows has progressed at slightly different paces. Certain features, such as Recall and Click To Do—available only on Copilot+ PCs equipped with advanced neural processing units (NPUs)—have been accessible on Arm versions for several weeks or even months prior to their introduction on x86 systems. Additionally, Windows 11 24H2 was available on Arm PCs in retail stores months before the update was disseminated to the wider PC ecosystem.
We have reached out to Microsoft for further details regarding the upcoming Windows 11 26H1 update, specifically to inquire about any potential enhancements that may benefit the broader PC ecosystem in the future. We will provide updates as more information becomes available.
