Windows 11’s Latest Update Brings Major Improvements for ARM PCs: A New Era of Software Compatibility
In the latest preview build of Windows 11, Microsoft has made significant strides in improving the compatibility of ARM-based PCs with x86 applications. Build 27744 introduces a highly anticipated update that enhances the functionality of Windows on ARM devices, making it easier for users to run demanding software and apps that were previously incompatible with ARM architecture.
The update brings a host of improvements, including an upgraded Prism emulator with expanded CPU extension support, such as AVX, AVX2, BMI, FMA, and F16C. This breakthrough allows ARM-powered devices, like those featuring Qualcomm’s Snapdragon X Elite and X Plus system-on-chips (SoCs), to run a wide range of applications and games that were previously limited to traditional x86-based PCs. This includes not only high-performance games like Starfield and Helldivers 2 but also professional software like Adobe Premiere Pro 2025 for video editing.
In this article, we’ll explore how this new update affects the performance and compatibility of ARM-based devices, the challenges Windows on ARM has faced, and what this means for the future of ARM-powered PCs.
The New Windows 11 Update: A Game-Changer for ARM Devices
Windows on ARM has been steadily improving over the past few years, with Microsoft’s ongoing efforts to refine its emulation technology. This latest update, Windows 11 Preview Build 27744, is a significant leap forward for the platform, offering enhanced compatibility and performance for ARM-powered devices.
Expanded CPU Extension Support: A Key Improvement
The standout feature of this update is the enhanced Prism emulator, which now supports a broader set of CPU extensions. These include:
- AVX (Advanced Vector Extensions)
- AVX2 (Advanced Vector Extensions 2)
- BMI (Bit Manipulation Instructions)
- FMA (Fused Multiply-Add)
- F16C (16-bit Floating Point Conversion)
These extensions are commonly used in many modern x86 applications, particularly in tasks involving heavy computations or media processing. By adding support for these extensions, the new update ensures that ARM-based devices can run complex, resource-demanding software like professional video editing tools and high-end games more smoothly.
Improved Compatibility for Demanding Applications and Games
One of the biggest hurdles for ARM-powered devices has always been their inability to run the vast majority of x86 applications, especially those requiring significant processing power. However, with the upgraded Prism emulator, this issue has been addressed.
Devices running ARM-based processors, such as the Qualcomm Snapdragon X Elite and X Plus chips, can now run applications that were previously incompatible. This includes graphically intense games like Starfield and Helldivers 2, which require powerful processors and advanced CPU features to deliver smooth gameplay. Moreover, professional video editing tools like Adobe Premiere Pro 2025 are now accessible on ARM PCs, opening up new possibilities for creative professionals who rely on these tools.
On-Screen Gamepad Keyboard for Enhanced Gaming
Another notable improvement in this update is the addition of an on-screen gamepad keyboard. This feature is especially useful for gaming handhelds and touchscreen devices, offering easier navigation and typing for users who prefer gaming on the go. The gamepad keyboard allows for a more streamlined gaming experience, making it easier to input commands, chat, or adjust game settings without needing an external keyboard or mouse.
Addressing the Compatibility Challenge: The Struggles of ARM Devices
When ARM-based Windows devices were first introduced, they promised long battery life, always-on connectivity, and improved energy efficiency. However, they faced a major roadblock—compatibility with the extensive library of x86 applications and software that Windows users have come to rely on.
Early Struggles with Software Compatibility
Initially, Windows on ARM devices could only run ARM-native applications or x86 apps via a limited emulator. This severely limited the usefulness of these devices, especially for users who needed to run professional software or play popular games that were only available on x86 architecture.
Despite these hurdles, Microsoft’s dedication to improving ARM support has led to steady progress, particularly in the area of emulation. Early updates focused on running legacy 32-bit x86 apps, but these efforts were limited by performance and compatibility issues.
The Breakthrough: Emulation and CPU Extension Support
With the release of Build 27744, Microsoft’s emulation technology has been taken to the next level. The enhanced Prism emulator now allows ARM devices to run not only older 32-bit applications but also modern 64-bit x86 software with much improved performance. The addition of support for advanced CPU extensions like AVX and AVX2 has played a crucial role in this improvement, particularly for applications that require intensive processing power.
The inclusion of these extensions makes it possible for ARM-powered devices to handle a wider range of applications, including resource-intensive programs that were previously reserved for traditional x86 PCs.
Improving Gaming Performance on ARM Devices
Gaming has long been one of the most challenging areas for Windows on ARM. Most modern games, particularly AAA titles, require high-performance hardware and sophisticated CPU instructions to run smoothly. Until now, the limited compatibility of ARM devices with x86 games meant that gamers had to rely on alternative devices or forgo playing certain titles altogether.
With the new update, however, gaming on ARM devices has become much more feasible. Titles like Starfield and Helldivers 2 are now playable, thanks to the enhanced emulator support for complex gaming requirements. This change could mark the beginning of a new era for ARM-powered gaming devices, as more game developers may be encouraged to optimize their titles for ARM platforms.
What Does This Update Mean for the Future of ARM-Based PCs?
Microsoft’s latest Windows 11 update for ARM devices is a huge step forward in expanding the ecosystem and improving compatibility with existing software. This update lays the groundwork for a more widely adopted ARM-based computing future, with the potential to redefine how users interact with their devices.
A Glimpse into the Future of ARM PCs
As more devices adopt ARM processors, the need for a robust software ecosystem becomes even more crucial. Microsoft’s ongoing improvements in emulation technology are helping bridge the gap between ARM and x86, allowing users to experience a more seamless computing experience on ARM-powered devices.
The improved compatibility for high-end software and games will be especially significant for professionals, content creators, and gamers, who have long been hindered by the limitations of ARM-based devices. As more developers optimize their applications for ARM, the performance and usability of these devices will continue to improve.
Windows on ARM: A Game Changer for the Industry
In the long run, the advancements in Windows on ARM could pave the way for a new class of devices that offer the best of both worlds: the power of x86 computing combined with the energy efficiency and always-on connectivity of ARM. These devices could change the way we think about mobile computing, gaming, and professional workstations.
