Fix / Workaround

Workaround: Setting "disableAllHooks": true stops the CMD windows, confirming the issue is in how Claude Code spawns child processes for statusLine/hooks. The fix is likely adding windowsHide: true to the Node.js child_process spawn options.

  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

Since approximately 2026-04-29, the statusLine command repeatedly opens CMD (console) windows on Windows 11 every few seconds.

Environment:

  • OS: Windows 11 Home (10.0.26200)
  • Claude Code: latest channel
  • Shell: Git Bash (bash)

What Should Happen?

Expected behavior: StatusLine command runs silently in the background with no visible console windows.

Error Messages/Logs

Steps to Reproduce

Steps to reproduce:

  1. Configure statusLine in ~/.claude/settings.json with any command (shell script, Python script, etc.)
  2. Start Claude Code on Windows 11
  3. Observe CMD windows repeatedly appearing on screen

Additional Information

Expected behavior: StatusLine command runs silently in the background with no visible console windows.

Actual behavior: A new CMD window appears every few seconds (matching the statusLine refresh interval). This also occurs with hooks commands.

Workaround: Setting "disableAllHooks": true stops the CMD windows, confirming the issue is in how Claude Code spawns child processes for statusLine/hooks. The fix is likely adding windowsHide: true to the Node.js child_process spawn options.

Note: This behavior started recently and was not present before. It affects both shell scripts and Python scripts as the statusLine command.

extent analysis

TL;DR

Adding windowsHide: true to the Node.js child_process spawn options may fix the issue of repeatedly opening CMD windows on Windows 11.

Guidance

  • Verify that the issue is indeed related to how Claude Code spawns child processes for statusLine/hooks by checking if setting "disableAllHooks": true stops the CMD windows from appearing.
  • Investigate the Node.js child_process spawn options to confirm if windowsHide: true is a valid and applicable solution.
  • Test the proposed fix by adding windowsHide: true to the relevant code and checking if the CMD windows no longer appear.
  • If the issue persists, try to isolate the problem by testing with different shell scripts and Python scripts as the statusLine command.

Example

No code snippet is provided as the issue does not include the relevant code, but the proposed fix would involve modifying the Node.js child_process spawn options, for example:

const childProcess = require('child_process');
childProcess.spawn(command, { windowsHide: true });

Notes

The proposed fix is based on the information provided in the issue and may not be applicable in all cases. The issue seems to be specific to Windows 11 and the latest version of Claude Code.

Recommendation

Apply the workaround by adding windowsHide: true to the Node.js child_process spawn options, as it is likely to fix the issue and has been confirmed to stop the CMD windows from appearing when "disableAllHooks": true is set.
