Microsoft has created a new setup experience in Windows that allows users to find, install, and launch AI agents in just two clicks, according to Peter Dawoud, principal program manager at the company. The change accompanies the debut of Nvidia's RTX Spark laptops, which combine Arm-based processors with Blackwell GPUs and shared memory to run powerful AI models locally. Hermes, Perplexity, and OpenClaw are the first three officially supported agents available through the Windows Store at launch, with Meta's Muse expected to join at some point in the future.
Beyond AI agents, Microsoft has extensively optimized its Prism emulation layer for RTX Spark's unique architecture. Because RTX Spark uses Arm chips rather than the x64 processors from Intel and AMD, apps without native Arm versions must run through an emulator. Dawoud says "emulation isn't generic" and that each platform requires tuning because "each core is different." Microsoft ships Prism updates monthly to improve compatibility, with particular attention paid to gaming performance, where CPUs control frame pacing while GPUs handle rendering. The company has also engineered memory optimization for RTX Spark devices, enabling Microsoft's Surface Laptop Ultra to support up to 128GB of unified memory while preserving system responsiveness. Users can manually adjust how much of that shared memory is dedicated to the GPU through a slider in Nvidia's Windows app, which proves useful for devices with 24GB or 32GB configurations.
Gaming support represents another major engineering effort for the RTX Spark platform. Microsoft and Nvidia have secured anti-cheat compatibility for Fortnite, Marvel Rivals, Arc Raiders, Counter-Strike 2, and Dota 2 at launch, with Activision's Ricochet engine (used in Call of Duty) slated for 2027 support, EA's Javelin anti-cheat for Battlefield arriving in early 2027, PUBG coming in the first half of 2027, and Riot Games committing to League of Legends and Valorant compatibility at an unspecified future date. Microsoft is also bringing its advanced shader delivery system from Xbox Ally devices to RTX Spark, allowing the Xbox app to precompile shaders during game downloads so players can launch immediately without waiting. Testing suggests medium settings at 1440p with DLSS performance mode delivers stable 60fps in most games, though performance varies by title and doesn't match dedicated gaming laptops.
The report notes that Copilot Plus PC features like Recall aren't available on RTX Spark devices at launch, with Adrienne Brewbaker, senior director of Windows marketing, stating these experiences are "expected to first become available to Windows Insiders later this year." Microsoft is also developing a redesigned Windows Search interface optimized for RTX Spark and other Copilot Plus PCs, transforming the search bar into a launcher with quick actions for tasks like toggling Bluetooth on or off. The platform's success hinges on balancing local AI power with practical usability—while large local models respond slower than cloud alternatives, they enable overnight processing and background tasks that don't require constant internet connectivity. The combination of Arm efficiency, GPU horsepower, and unified memory architecture positions RTX Spark as a distinct category between traditional Windows laptops and AI-focused workstations, though developers and users will need to accept the trade-offs inherent in a platform that relies heavily on emulation and newer toolchains.
