Windows: Bash commands spawn visible black console windows

Problem

On Windows, every time Claude Code executes a Bash command, a black console window briefly appears on screen. This is disruptive, especially during multi-step tasks that run many commands in sequence.

Root Cause

When Claude Code spawns bash.exe (Git for Windows) as a child process, it does not set the CREATE_NO_WINDOW process creation flag. Windows therefore creates a visible console window for each spawned process.

Expected Behavior

Bash commands should execute silently in the background with no visible console window, similar to how background processes behave in macOS/Linux.

Suggested Fix

Pass CREATE_NO_WINDOW (or windowsHide: true in Node.js child_process.spawn() options) when spawning shell processes on Windows.

Alternatively, expose a user-configurable setting in settings.json such as:

{
  "windowsHide": true
}

Environment

• OS: Windows 11 Enterprise
• Shell: Git Bash (C:\Users\...\AppData\Local\Programs\Git\usr\bin\bash.exe)
• Claude Code: VSCode extension / Desktop app
