Microsoft and NVIDIA open Surface Laptop Ultra pre-orders and ship agent containers

Microsoft and NVIDIA used a Windows and Surface event in San Francisco on 7 October 2026 to present local AI agents as the next job for the personal computer. Microsoft published two announcements the same day, one on Windows and one on Surface devices.[1][2][3]

Three items matter most. MXC is now generally available. RTX Spark laptops are open for pre-order. DGX Station for Windows was previewed. Each is a company claim at this stage, and none has independent testing yet.[1][2][3]

Microsoft says MXC is operating-system infrastructure that lets agents run safely and persistently in the background. Organisations define which files and networks an agent may access, and Windows enforces those policies at runtime. Microsoft links MXC to its Agent 365 and Intune tools so that agent activity can be governed.[1][3]

NVIDIA quotes Microsoft executive Pavan Davuluri: "We are building these primitives directly into Windows, so agents can be secured, observed and governed." General availability describes the software, not its record. No outside security test of MXC is cited in either company post.[3][1]

Surface Laptop Ultra has a 15-inch touchscreen and the RTX Spark chip, which pairs a Blackwell GPU with up to 6,144 cores and a Grace CPU with up to 20 cores. Microsoft lists up to 128 GB of unified memory and up to one petaflop of AI performance. It says the laptop can run models above 120 billion parameters locally.[2][3]

The laptop starts at US$2,599 and ships from 16 October 2026. A Surface RTX Spark Dev Box costs US$5,999, ships in November and is sold only through Microsoft.com in the United States. NVIDIA says RTX Spark compact desktops follow in November, with systems from Acer, ASUS, Dell, HP, Lenovo, MSI and Gigabyte.[2][3]

NVIDIA previewed DGX Station for Windows as a deskside system on the GB300 Grace Blackwell Ultra chip, with 748 GB of coherent memory and up to 20 petaflops of FP4 compute. NVIDIA says that is enough for models up to a trillion parameters, run locally.[3]

The post gives no price, no ship date and no region, and invites readers to sign up for news. Until those arrive, this is a product direction rather than a purchase option for any Malaysian buyer.[3]

One petaflop and 20 petaflops are peak figures at FP4, a low-precision number format. Real speed depends on the model, memory use and software. Our reading is that the 128 GB ceiling, not the petaflop figure, decides which models fit on a laptop.[3][2]

Both companies publish these figures themselves. We found no independent benchmark of RTX Spark, MXC or Surface Laptop Ultra, so treat every speed and capacity claim as unverified until reviewers test shipping units.[3][2][1]
