Windows system utilities like ipconfig, systeminfo, etc. write directly to the console via WriteConsole API instead of stdout. When Node.js spawns cmd.exe with piped stdio, these utilities produce empty output. Changes: - Switch from cmd.exe to PowerShell on Windows (properly redirects output) - Disable detached mode on Windows (PowerShell doesn't pipe stdout when detached) - Add windowsHide option to prevent console window flashing - Update tests to use PowerShell-compatible syntax (Start-Sleep, semicolons)
