Microsoft pairs local AI PCs with shared Microsoft 365 storage changes

Microsoft says it is building Windows as a hybrid-intelligence platform, where agents can run locally or use the cloud as needed.[1] Its approach routes tasks to an appropriate model based on the work and available capabilities.[2] Microsoft Execution Containers are now generally available on Windows 11, giving organizations a way to define which files and networks agents can access.[1] Microsoft says the containers already support OpenAI Codex, GitHub Copilot, OpenClaw, Replit and LM Studio.[1] For organizations assessing agent deployments, the announcement pairs model choice with a defined boundary for agent access.

Microsoft says MAI Code 1.1 Flash has 137 billion total parameters and 6.8 billion active parameters, and is designed for coding workloads.[1] It uses 3-bit precision to reduce model size by nearly 80% while supporting a 256K context window locally.[1] Microsoft also announced Windows ML support for llama.cpp, giving developers more open-source model options.[1] HydraFusion-powered hybrid intelligence is expected in experimental preview in the Copilot app, Copilot CLI and Visual Studio Code later in October.[1]

Microsoft opened pre-orders for the Surface Laptop Ultra and Surface RTX Spark Dev Box as part of its hybrid-intelligence hardware push.[4] The Laptop Ultra is built around NVIDIA RTX Spark, offers up to 128 GB of unified memory, and can run AI models exceeding 120 billion parameters locally.[4] Microsoft says it delivers up to one petaflop of AI performance and is less than 18 mm thin and under 4.5 pounds.[4] It starts at $2,599, is available to pre-order from Microsoft and select retailers worldwide, and begins availability October 16.[4] The Dev Box offers up to one petaflop and 128 GB of unified memory; it costs $5,999, is exclusive to Microsoft.com in the United States, and begins shipping in November.[4]

Microsoft 365 Family and Premium include 2 TB of shared cloud storage for the primary subscriber and up to five additional members.[5] The previous arrangement gave a family of six a combined 6 TB, making the new pool a 66.7% reduction in total available storage, according to Neowin’s calculation.[6] New and upgraded subscriptions moved to shared storage on October 8, 2026; existing subscribers generally switch after their first renewal on or after May 2, 2027.[6] Microsoft says sharing the quota does not expose members’ files to one another unless content is explicitly shared, and members’ add-on storage joins the pool.[5] Microsoft cited Copilot and other AI-powered Office features to justify price increases.[6]
