Windows: cowork scheduled tasks flash visible WSL console window every few minutes

Resolved 💬 3 comments Opened Mar 21, 2026 by giquina Closed Mar 25, 2026

Description

On Windows 11, the cowork scheduled tasks feature (coworkScheduledTasksEnabled / ccdScheduledTasksEnabled) periodically spawns wsl.exe, which opens a visible console window that flashes on screen every ~5 minutes. This interrupts active work (typing, browsing, form entry) by stealing focus momentarily.

The window title bar shows C:\Program Files\WSL\wsl.exe and it opens and closes within a second or two.

Steps to reproduce

  1. Windows 11 Pro (10.0.26200) with WSL2 installed
  2. Claude Desktop v1.1.7714.0
  3. Enable coworkScheduledTasksEnabled: true and ccdScheduledTasksEnabled: true in claude_desktop_config.json
  4. Use the computer normally — within ~5 minutes a wsl.exe console window will flash open and close

Expected behaviour

Background wsl.exe invocations should be invisible to the user. The process should be spawned with CREATE_NO_WINDOW or DETACHED_PROCESS flags, or use wslservice instead.

Workarounds attempted (none fully work)

  • PowerShell script polling to hide windows: Too slow, window still flashes briefly
  • Windows Terminal as default console host: WSL calls open as tabs in the active terminal, still disruptive
  • Windows Terminal with windowingBehavior: "useNew": Opens new terminal windows, still visible

Environment

  • Windows 11 Pro 10.0.26200
  • WSL version 2.6.3.0
  • Claude Desktop v1.1.7714.0 (Windows Store)
  • Default WSL distro: docker-desktop

Suggested fix

When spawning wsl.exe on Windows, use CREATE_NO_WINDOW process creation flag:

// Node.js example
const { spawn } = require('child_process');
spawn('wsl.exe', [...args], {
  windowsHide: true,  // Sets CREATE_NO_WINDOW
  stdio: 'pipe'
});

This is a one-line change (windowsHide: true in Node.js spawn options) that would fix the issue for all Windows users.
