According to God of Prompt on X, Anthropic’s Cowork has launched on Windows with full feature parity—file access, multi‑step task execution, plugins, and MCP connectors—mirroring its macOS release a month earlier (source: God of Prompt, Feb 11, 2026). As reported by the same thread, Microsoft invested roughly $37.5B per quarter in AI infrastructure, preinstalled Copilot on Windows 11, ran $60M+ in TV ads, and serves 450M M365 paid seats with 15M Copilot subscribers—a 3.3% conversion—while market share purportedly fell from 18.8% to 11.5% in six months (source: God of Prompt). According to the post, enterprises hesitate because Copilot inherits M365 permissions via Microsoft Graph, enabling sensitive data surfacing with natural language and triggering governance audits that delay rollouts (source: God of Prompt). By contrast, Cowork reportedly sandboxes Claude to a single folder with no Graph layer, enabling targeted automation without enterprise‑wide permissions risk, and was built in about 1.5 weeks using Claude Code (source: God of Prompt). For AI buyers, the business implication is near‑term ROI from lightweight, folder‑scoped agents versus multi‑year permission re‑architecture, positioning Anthropic’s Claude Opus 4.6—with improved agentic planning and 1M token context in beta—as a practical Windows automation choice while Copilot undergoes permission audits (source: Anthropic via @claudeai).
