NVIDIA, Microsoft unveil MXC and DGX Station for Windows AI agents

The announcement builds on Microsoft's effort to turn Windows into a secure platform for AI agents, with MXC as the foundation. By embedding this capability into the OS, Microsoft aims to let agents be protected, monitored and managed, and it says MXC, Microsoft Security and Agent 365 together can maximize agent potential on Windows.

On the hardware side, the Surface Laptop Ultra is presented as built around NVIDIA RTX Spark, with up to 128GB of unified memory and up to 1 petaflop of AI compute, which Microsoft says allows models that previous machines could not handle. NVIDIA also previewed the DGX Station for Windows, bringing GB300 Grace Blackwell-class AI infrastructure to a deskside AI supercomputer that can run frontier-class models locally, with up to 748GB of memory and up to 20 petaflops of FP4 AI compute — enough for models up to 1 trillion parameters.

What ties these pieces together is the push to make AI agents always-on and directly connected to existing Windows applications and infrastructure. The fact that the DGX Station previously ran on Linux and now supports Windows, while still allowing Linux AI tools via WSL, suggests NVIDIA and Microsoft are trying to bridge the two environments for developers. The announcement did not provide dates for general availability of MXC or for broader availability of the DGX Station.
