Microsoft has made Microsoft Execution Containers generally available in Windows, giving AI agents an operating-system-controlled environment for persistent background work. The company says the containers let administrators isolate, observe and govern agents instead of granting them unrestricted access to a user’s desktop.
At the same event, Nvidia and Microsoft detailed RTX Spark laptops and compact desktops for running larger models locally. Laptop preorders are open, with availability scheduled for October 16; compact desktops are planned for November. Vendors include Acer, Asus, Dell, HP, Lenovo, Microsoft, MSI and Gigabyte.
RTX Spark combines a Blackwell-class RTX GPU with a Grace CPU, up to 128GB of unified memory and a claimed one petaflop of low-precision AI performance. Nvidia positions that capacity for local models and always-on agents that can keep data on the machine. The same CUDA software stack can also move workloads to larger Nvidia systems.
Microsoft additionally previewed a Windows version of DGX Station using the GB300 Grace Blackwell Ultra Desktop Superchip, with 748GB of coherent memory. No general availability date was provided. Hardware capacity and isolation tools make local agents more practical, but organizations still need narrow permissions, monitoring and approval controls for consequential actions.
