Research direction

Start at the Electron child_process.spawn entry points that launch cmd.exe, powershell.exe, or rtk.exe, then reproduce the process chain on Windows 10/11. Verify that command execution no longer creates visible conhost.exe windows while the child processes still run, using Task Manager or the WMI event listener described in the report.

Description

bug
GUI version

v0.1.43

Operating system

Windows

Reproduction steps
  1. Install and launch Command Code Desktop (version 0.1.43) on Windows 10/11.
  2. Leave the application running in the background (or even close it, if residual processes remain).
  3. Watch Task Manager or the screen: conhost.exe windows appear and disappear constantly.
  4. To confirm the origin, a WMI event listener (e.g. Register-WmiEvent in PowerShell) can be used to capture the process chain.
Expected behavior

Command Code Desktop should spawn child processes (such as cmd.exe, powershell.exe, rtk.exe) without displaying a console window. This is achievable by passing the CREATE_NO_WINDOW flag (0x08000000) to CreateProcess, or the equivalent windowsHide: true in Electron's child_process.spawn.

Actual behavior

Every time the application (or a residual process) executes a command, a new console window is allocated and displayed. The captured process chain is:

Command Code.exe (GUI, no console) → cmd.exe /d /s /c "powershell.exe -EncodedCommand ..." → conhost.exe (window)

This repeats dozens of times per minute.
