Looks like Windows Arm’s problems might be over. Microsoft has redesigned key Windows 11 components to better accommodate Arm-based hardware and AI as part of the company’s new Copilot+ AI PC program, which also includes new Surfaces and partner systems on Qualcomm’s Snapdragon X Elite CPUs. Better still, an emulator called “Prism” for running older x86 and x64 software is included. Other changes include a new kernel and compiler.
Arm capabilities and AI workloads, Windows 11 schedulers were modified
Though it’s okay if you’re dubious. Microsoft has shown time and again that it cannot be relied upon to provide a serviceable operating system on Arm, beginning with the release of the Surface powered by Windows RT in 2012.
That device was significantly slower than PCs with Intel and AMD CPUs, and it was unable to run legacy x86 applications (who would want to do that in Windows, right?). Over time, Windows on Arm steadily became better until it could run a decent emulator on the Surface Pro 9 5G. However, that slate was still unable to match the performance of its Intel-equipped brother, particularly when it came to emulating well-known programs like Chrome.
Microsoft claims that in order to benefit from Arm capabilities and AI workloads, Windows 11 schedulers were modified. Along with AI APIs integrated right into the OS, there’s also a new driver compute model that perceives neural engines in a manner similar to how Windows perceives CPUs and GPUs.
In other words, developers should find it easier to access AI capabilities and Arm hardware should no longer feel like an afterthought.
Pavan Davuluri, Microsoft’s president of Windows and Devices, told reporters during a briefing earlier this month, “So, effectively, we’re building binaries and windows that are optimized with certain workloads.” “The benefit for us for that is there are certain things that we know customers with Copilot+ PCs are going to do on an ongoing basis, and we can really focus
As a measure of a chip’s AI performance, Copilot+ PCs can execute more than 40 trillion operations per second, more than four times the performance provided by current AI PCs.
This is made possible by a potent new Neural Processing Unit (NPU) in the Snapdragon X Elite CPUs. Apple’s MacBook Air and MacBook Pro only give half the performance that Microsoft claims this to be.

Supporting older software is crucial, even while Microsoft is working to make more native Arm apps available for Windows 11. Prism emulator is useful in this situation. According to Microsoft, it is about 20% faster than its previous emulator and supports a greater variety of programs.
Microsoft stated in a blog post that any x86 and x64 apps that utilize the Snapdragon X Elite Arm processors for emulation are more than twice as quick as earlier iterations of Windows that operated on Arm.
Additionally, Microsoft is able to incorporate AI-powered software capabilities into Windows thanks to the NPU. One such function is called Recall, which works with AI to recover almost anything you’ve ever seen on your computer. Microsoft likens this to giving your machine a photographic memory. Live Captions is an additional function that allows you to instantly and in real-time translate any video or audio that is playing on your computer into English from 44 other languages.
