Microsoft has published a new blog post celebrating significant progress around the Windows on Arm platform over the last year. The company is excited to welcome NVIDIA to the Windows on Arm family with its RTX Spark SoC later this year, joining the Qualcomm Snapdragon X platform and solidifying the Windows on Arm platform as here to stay.

"The market is sending a clear signal: more silicon providers and more OEM partners are investing in Windows on Arm because customer demand is growing for these powerful and efficient Windows devices and experiences," says Klaus Diaconu, Partner Director at Microsoft. "In the fall of 2026, devices from Microsoft Surface, ASUS, Dell, HP, Lenovo, and MSI will be available [with RTX Spark.]"

In addition to highlighting silicon and hardware makers bringing Windows on Arm to market, Microsoft is also excited to spotlight Windows apps that are now available on the Arm platform, including STEM and education apps, security apps, productivity apps, creativity apps, entertainment and media apps.

"Productivity apps remain the cornerstone of how people get work done on Windows. Whether managing projects, collaborating with teammates, organizing information, or communicating across teams, these apps are essential to our customers’ daily work. The growing list of productivity apps now available reflects both customer demand and increasing momentum from developers building with Arm as a first-class Windows platform."

Some of the highlights include apps like Sharex, Proton Mail, Signal, Discord, FxSound, and more. In fact, Microsoft says there are now over 7,000 compatible Windows on Arm apps being tracked on the "Works on WOA" website, which the company recommends as a comprehensive source for app compatibility information.

While most mainstream apps are now natively supported on Arm, there are still Windows apps that don't yet have an Arm native version. With the Windows Prism emulation layer, these apps still run on Windows on Arm, and on the latest Arm PCs they feel native thanks to improvements to performance from both the silicon and software.

"Windows on Arm is no longer defined by potential, but by a rapidly expanding ecosystem of devices with apps available across workloads that customers depend on most," Microsoft states. "As developers continue to invest in Arm-native experiences and compatibility, customers gain more choices, flexibility, and confidence in adopting the next generation of Windows devices."

Windows 11 will soon let you pick how much unified memory is reserved for graphics and AI. The feature is hidden in a recent Windows Insider build (29648) and was discovered by X user @XenoPanther.

Unified memory is high-bandwidth memory that can be shared between a CPU, GPU, and other processors. Traditionally, PCs with discrete graphics cards have dedicated VRAM (video memory) that lives separately from other memory.

Unified memory is still relatively new to PCs. The upcoming NVIDIA RTX Spark lets you use up to 128GB of unified RAM. AMD's Ryzen AI Max already features unified RAM.

Apple popularized the concept of unified memory with its M-Series chips, though the technology is not exclusive to Apple.

If the unified memory feature in testing rolls out, Windows 11 will have a key differentiator from macOS.

Microsoft's new feature lets Windows 11 users "reserve additional unified memory for graphics and AI intensive games and applications." The setting would help ensure smooth performance for certain types of workloads that require a lot of memory.

Normally, Windows manages shared memory dynamically, shifting resources back and forth as apps demand them. That approach works fine for general multitasking, but it runs into problems with heavy workloads like local AI inference or 3D gaming.

When memory is shared like that, background OS tasks and apps can contend for the same pool of RAM. That competition can cause latency spikes, frame drops, or total out-of-memory crashes when you're trying to run something demanding.

By letting users reserve memory, workloads with high demands for graphics and AI have uninterrupted access to high-speed memory.

The feature is not finished and has not been announced by Microsoft, so it requires some extra work to see. You can force it to appear using ViveTool.

I'd recommend waiting until the feature enters testing or even ships to general users before using it. In most cases, it's worth letting Microsoft work out any issues and polish the experience rather than use a hidden feature.

Microsoft continues to improve Windows 11. Just this past week, the company began testing new context menus with Windows Insiders and revamped the ancient AutoPlay dialog box.

The Windows K2 initiative to improve the operating system is going so well that I've asked if the next big update should be Windows 12. But fixing the Windows experience is about more than context menus and a unified user interface. Even if Windows is fixed, Microsoft needs to make better apps.

If a person logs onto a PC running a beautiful and zippy version of Windows 11, they won't care about the OS if Microsoft Teams takes too long to load. Microsoft needs to lead by example by making the best Windows apps.

Biggest News of the Week

To give Microsoft credit, work is being done to improve some apps. Rudy Huyn, a well-known Windows developer who worked on the Microsoft Store, is putting a team together to improve Windows apps. That team is still in its infancy, so we will have to wait to see the results.

But Microsoft's app issue isn't just about having a team dedicated to in-box apps or hiring good developers. It's about the direction Microsoft pushes those developers. Microsoft Teams and other Microsoft apps have been "rebuilt from the ground up" or "refreshed with performance in mind" several times over the years. But the underlying problem still exists. Microsoft made the wrong choice by going all-in on web apps, and it needs to course correct.

Huyn's team is all about native apps, but it's not clear right now how many apps will fall under its umbrella. Will we see a new native version of Outlook? What about Microsoft Teams? If Huyn's team is just focused on in-box apps, some of the most-used apps on Windows 11 will remain laggy web apps.

Plus, several of Microsoft's biggest apps aren't even in the same part of the company as Huyn's team. If Microsoft fixes the Photos app, OneDrive, and other in-box apps, but Teams is still laggy, Microsoft is still delivering a poor user experience.

Shopping with Sean

Speaking of apps, this week's top deal is on the ever-popular Microsoft 365. That software suite is massively discounted right now if you bundle it with NordVPN. You'll get the best value if you use both Microsoft 365 and NordVPN, but the bundle is more affordable than Microsoft 365 on its own.
