Summary
After a desktop-app update on 2026-08-10, Computer Use on Windows fails before it can enumerate or control windows. The user asked the agent to test mouse control; no mouse movement or click was performed because window discovery immediately failed.
The direct Computer Use runtime returns: await sky.list_windows() -> spawn EPERM.
This prevents the agent from seeing any Windows application window, including Chrome, and therefore prevents mouse/keyboard automation.
Impact
Computer Use cannot select or control any Windows app window. The user cannot use the advertised mouse-control workflow.
Privacy
No files, credentials, or screenshots are attached. No mouse click was executed during the failed direct-control test.
