In brief
Anthropic has no fix yet for Cowork on Windows, and reinstalling will not bring it back
A Windows update released on 8 September stopped Claude Cowork on Windows from running local commands, Anthropic’s status page says. Its workspace “can no longer reach your computer’s drive.” Chat and file edits still work. Anthropic says there is “no in-app workaround yet, and restarting or reinstalling won’t help,” and the incident has stayed open since 15:54 UTC on 10 September. The verdict: until it closes, Cowork on Windows is a chat window, not an agent.
What it changes Move any Cowork workflow that runs local commands to macOS or to a terminal agent until the incident closes.
