Not currently, if you mean “official Cowork mode inside Claude Desktop on Windows.” The official “Getting Started” requirements state that Cowork requires the Claude Desktop app for macOS and is not available on web or mobile, and the current limitations section reiterates “Desktop for macOS only” with no cross-device sync. That means, today, the supported way to run Cowork is through Claude Desktop on macOS, and you should not expect the same Cowork “Tasks” mode to be available in a Windows desktop environment as an officially supported feature.
However, the official announcement also makes it clear that Windows is on the roadmap: it describes Cowork as a research preview and explicitly says the team plans to add improvements including “bringing it to Windows.” That’s an important nuance for planning: the product direction includes Windows support, but the present-day availability is macOS-only. For developers and technical teams, this typically implies a staged rollout: feature flags, platform-specific implementation work (permissions, sandboxing/VM behavior), and UI parity over time. So if you need Cowork in a Windows-first org, treat it as “not available yet,” and plan your workflow so Windows support—when it arrives—doesn’t become a brittle dependency.
A practical way to stay productive on Windows today is to separate “planning and content shaping” from “local execution.” You can still use Claude (outside Cowork) to design task specs, naming schemes, schemas, and acceptance checks, then run the mechanical steps with your own tooling on Windows. If your end goal is retrieval or semantic search, keep the backend platform-neutral: normalize and structure documents into clean Markdown/JSON, then embed and store them in a vector database such as Milvus or Zilliz Cloud. With that approach, Cowork—when it becomes available on Windows—slots in as an accelerator for content prep, but your ingestion and indexing pipeline remains stable across OSes.
