Launch your preferred shell
You can now specify which external shell VS Code will launch when you use commands like Open in Command Prompt (or Open in Terminal on OS X or Linux). Set the externalTerminal user or workspace setting for your platform (windowsExec, linuxExec) to the executable to launch (cmd is the default for Windows).
For example, to set PowerShell as your external shell on Windows and Terminator on Linux, use:

{
    "externalTerminal.windowsExec": "powershell",
    "externalTerminal.linuxExec": "terminator"
}

とりあえずお気に入りのConEmuをユーザのsettings.jsonに追記しておく。
