Microsoft is changing Windows to make local agents easier to install and large AI models easier to run on Nvidia’s RTX Spark laptops. Its work also includes tuning x64 app emulation for Nvidia’s Arm CPU and managing the memory shared by the CPU and GPU, according to Tom Warren’s report in The Verge.
The software arrives in stages. Agent installation is part of the launch experience, while Copilot Plus PC capabilities such as Recall are due later. That makes the particular Windows feature a buyer needs as important as the laptop’s hardware specifications.
Easier agent setup, with an early snag
Microsoft’s new Get Started experience lets RTX Spark owners choose and install an agent in two clicks, principal program manager Peter Dawoud told The Verge. The Windows Store handles agent installation and updates. Hermes, Perplexity and OpenClaw are the first officially supported agents, with Microsoft working to add others.
Warren found Hermes largely matched the two-click setup claim. OpenClaw required an uninstall and reinstall after it complained about a missing local gateway. His early use also found large local models slower to answer prompts than cloud models. He suggested background or overnight tasks as a possible use, while saying more testing was needed to judge the agents’ value beyond coding.
Memory capacity and app compatibility
RTX Spark combines an Arm CPU, a Blackwell GPU and unified memory. Microsoft has tuned memory management so large models can use much of that capacity while Windows and other apps remain responsive. Surface Laptop Ultra configurations can reach 128GB, according to the report.
Nvidia’s Windows app also has a slider for adjusting how much memory goes to the GPU. The report points to its use on 24GB and 32GB machines, where users may want to change the allocation for particular apps or games.
Apps without native Arm versions use Microsoft’s Prism emulator. Dawoud says Microsoft tuned translation of x64 software for RTX Spark’s CPU design. He also says the Windows team ships compatibility improvements every month.
Gaming support shows why that work extends beyond emulation. The report lists Fortnite and Counter-Strike 2 among titles supported at launch. Call of Duty’s Ricochet support is planned for 2027, while EA targets early 2027 for Battlefield’s Javelin anti-cheat. Microsoft is also bringing advanced shader delivery to RTX Spark so the Xbox app can preload shaders during a game download.
More Windows features are still coming
Microsoft expects Copilot Plus PC experiences on RTX Spark to first reach Windows Insiders later this year, Windows marketing executive Adrienne Brewbaker told The Verge. Warren reports that full availability appears likely next year. Recall is among the capabilities absent at launch.
Microsoft is also developing a faster Windows Search interface with actions such as switching Bluetooth on or off from the search bar. The report gives no firm release date for that interface.
