Microsoft has unveiled Prism, an emulator designed to let x86 applications run on new computers powered by ARM processors. The company positioned Prism as a key feature of the Windows 11 24H2 release, with coverage in TechSpot and other tech portals confirming its arrival. Prism aims to bridge software compatibility gaps as hardware shifts toward ARM-based systems, making it possible for many familiar programs to operate smoothly on newer devices without waiting for native ARM ports.
In discussions about Prism, observers compared its potential to Apple’s Rosetta 2, which helped x86 apps run on Apple Silicon after Apple moved away from Intel CPUs. The comparison underscores Prism’s role in easing transition pains for users who rely on legacy software while exploring ARM’s efficiency and performance gains. By enabling a wide range of x86 software to function on ARM, Prism could reduce friction for consumers and enterprises alike as devices evolve toward a more power-efficient architecture.
The Windows 11 24H2 maintenance update is being optimized to run the operating system more effectively on ARM devices, with a particular emphasis on devices powered by Qualcomm Snapdragon X-series processors. Microsoft envisions Prism as a catalyst that unlocks the full potential of new form factors and hardware features, including built-in neural processing units (NPUs) that are increasingly integrated into modern devices. For users who perform AI tasks, Prism holds the promise of smoother workflow and faster processing by leveraging ARM-native accelerators alongside traditional emulation pathways.
Microsoft notes that Prism will not be necessary for every user. Many popular applications already offer Arm64-native builds or cross-platform versions that work well across architectures. Core productivity tools such as Office, Teams, PowerPoint, and Outlook are frequently available in Arm-friendly formats, while creative and professional suites like Adobe Photoshop, DaVinci Resolve, Blender, and similar software have either native ARM support or robust cross-platform options. Web browsers, including Mozilla Firefox, Opera, and Chrome, also provide Arm-optimized builds, reducing the need to rely on emulation for everyday web tasks. In practice, this means a large portion of users may experience seamless performance without engaging Prism, while those with specialized software still benefit from ongoing ARM compatibility improvements.
Earlier reports noted broader industry momentum around ARM-friendly ecosystems. For instance, there was mention that Samsung would limit Android 15 updates to a subset of its existing devices, with estimates suggesting that fewer than a third would receive the upgrade. This context helps explain why tools like Prism could be crucial for maintaining continuity as hardware platforms transition—emulation can help preserve access to essential applications while manufacturers roll out native ARM optimizations and developer support.
