879929**Known issue: Cowork on Windows**
880930
9312026-09-10
932
881933**Resolved September 14, 2026.** Microsoft has released a Windows update that fixes this issue. Install the latest Windows update and restart your PC.
882934
883935A Windows update released September 8, 2026 (including KB5124008) stops Cowork from reaching your files when it runs on your Windows PC, so tasks fail or the workspace does not start. This affects Cowork on third-party inference deployments and Cowork sessions that run on your computer rather than in the cloud. Cloud sessions and Claude Code, including the Code tab, are not affected. Chat cloud sessions are not affected, but Chat sessions on third-party inference deployments are affected if using advanced file analysis. The cause is a change in Windows, so restarting or reinstalling Claude does not help.
