NVIDIA and Microsoft bring AI agents to Windows PCs

NVIDIA CEO Jensen Huang and Microsoft CEO Satya Nadella outlined a joint push to make Windows PCs a platform for AI agents, pairing Microsoft’s operating system work with NVIDIA hardware and software. Microsoft announced the general availability of Microsoft Execution Containers, or MXC, OS-level infrastructure designed to let agents run safely and persistently in the background under operating system control.

RTX Spark will bring the full NVIDIA AI stack to Windows laptops and compact desktops, with laptop preorders opened at the event and availability Friday, Oct. 16. Compact desktops are expected in November. Systems are planned from Acer, ASUS, Dell, HP, Lenovo, Microsoft, MSI and Gigabyte, spanning slim laptops and small desktops built for always-on agents.

The RTX Spark platform combines an NVIDIA Blackwell RTX GPU with up to 6,144 cores and an up to 20-core NVIDIA Grace CPU connected at 600 GB/s. NVIDIA said the systems can support local AI workloads with up to 128GB unified memory and run models such as Qwen 3.8 Flash Next without sending data to the cloud.

NVIDIA also previewed DGX Station for Windows, bringing GB300 Grace Blackwell-class AI infrastructure into the Windows ecosystem. The deskside system runs on the GB300 Grace Blackwell Ultra Desktop Superchip, delivering 748GB of coherent memory and up to 20 petaFLOPS of FP4 AI compute for local model development, fine-tuning and inference.
