Microsoft readies Windows for Nvidia RTX Spark AI laptops with agent store, Prism tuning, and unified memory tweaks

KEY POINTS

1. Microsoft and Nvidia showcased RTX Spark laptops and Microsoft has updated Windows to better support local AI agents and Arm‑based RTX Spark hardware.
2. Changes include a new Get Started flow and Windows Store integration for AI agents (Hermes, Perplexity, OpenClaw at launch), Prism emulator optimizations for x64 emulation on Arm, and unified memory and power/performance tuning (e.g., Surface Laptop Ultra support up to 128 GB unified memory and an Nvidia app slider for GPU memory allocation).
3. This matters because Windows-level support for local agents, Arm emulation tuning, and unified memory allocations make running larger AI models and agent workflows on RTX Spark laptops more practical for users and developers.
