Microsoft Just Gave Your PC an AI Team (We Tested It)

Microsoft just gave your PC an AI team. At its Oct 7 event, Microsoft rebuilt its Windows pitch around "hybrid intelligence": AI agents that run on your own PC when they can, use the cloud when they must, and get their own locked-down account. Then we ran our own AI agent team, locally, for $0. The PC is about to stop being a machine you do everything on yourself — and start being a team that works for you. QUICK FACTS (checked Oct 12, 2026) Microsoft Execution Containers (MXC): generally available on Windows 11; per-agent containment enforced at runtime, plus separate agent identities. Copilot on Copilot+ PCs gets local context, local actions and local models — expected to roll out "in the coming months." Surface Laptop Ultra (Nvidia RTX Spark): from $2,599, Oct 16; the 128 GB version that runs 120B+ models is about $5,899. MAI Code 1.1 Flash runs locally at ~3.3 bits: 70.8% vs 72.6% on SWE-bench Verified (Microsoft's numbers). Microsoft-Decision-1: a 9B decision model, $0.042 per million input tokens, output free; 35x faster than GPT-6 Sol in Microsoft's benchmark. OUR TEST 24 made-up tax files sorted by a local Qwen3-4B model (llama.cpp, 8 CPU cores, no GPU, $0). One agent: 19.6 s, 18/24 Four parallel subagents: 18.7 s, 18/24 Four subagents + three sentences of shared context: 24.1 s, 23/24 One shot each, no edits. The lesson: a team only beats one agent when every helper sees the same picture.

Would you give an AI agent its own account on your computer? What would you let it do — and what never? Tell me in the comments.
