What's Wrong?

Environment:

• OS: Windows 11 Pro
• Cowork Version: Version 1.1.2685 (f39a62)
• Download Date:02/12/2026

Issue:
Cowork workspace fails to start with "VM connection timeout after 60 seconds"
Cannot reach Claude API from workspace.

Root Cause:
Network diagnostics module runs macOS-specific commands on Windows:

• /sbin/ifconfig (should be: ipconfig)
• /usr/sbin/scutil (should be: Windows equivalent)

These commands fail on Windows, causing 60-second timeout.

Steps Taken:

• Uninstalled and reinstalled
• VM boots successfully but network fails

Expected:
Windows should use appropriate Windows networking commands (ipconfig, etc.)

Additional Context:
This affects Windows support that launched Feb 10, 2026.
