Microsoft Execution Containers went GA on Windows 11 on 7 October 2026, alongside GitHub Copilot local sandboxing, so the OS now enforces which files and hosts an agent can reach. Intune policy and Entra agent attribution are still "coming soon" with no date, which leaves the agent developer drawing the boundary and the employee's name on every action; here is what to enforce now, what to defer, and the Cloud PC cost math.

Claude Opus 5.5 is GA in Microsoft Foundry at $4/$20 per million tokens with cache reads at $0.20, which cuts a cache-heavy 60-turn agent session from $8.63 on Opus 5 to $5.10 and brings it within 1.5x of Sonnet 5. The saving can reverse on uncached endpoints that ran Opus 5 with thinking disabled, because thinking is now always on, the default effort dropped to medium, and Foundry still offers no EU data zone, batch pricing or fast mode.

GitHub ported the Copilot agent runtime from TypeScript to 832,378 lines of production Rust in about 14.5 weeks for roughly $120,000 in tokens plus three weeks of one developer's time, with a 96.22% prompt-cache hit rate and up to 18x faster in-process session startup. We break down the token bill into reusable unit costs, show why caching kept it around a sixth of the uncached price, and list the preconditions and EU residency checks to settle before budgeting your own agent-driven rewrite.

GPT-6 Astra reached Microsoft tenants through four doors in 48 hours: Foundry, Copilot Cowork, Copilot Studio and GitHub Copilot, two of them on by default. Each door has a different operator, data path, meter and off switch, from OpenAI running as a Microsoft subprocessor inside the EU Data Boundary to GitHub billing at list price. Here is the map and the admin checklist for a Swedish tenant.

GitHub’s new Copilot desktop app runs multiple coding agents in parallel, each session isolated in its own git worktree, and is already included in Copilot Pro, Pro+, Business and Enterprise subscriptions. Getting value from it depends less on prompting than on task selection, worktree hygiene, supervision cadence and engineered review capacity, because five agents can open pull requests faster than one reviewer can read them.
