The Windows Terminal is a modern, fast, efficient, powerful, and productive terminal application for users of command-line tools and shells like Command Prompt, PowerShell, and WSL. Its main features include multiple tabs, panes, Unicode and UTF-8 character support, a GPU accelerated text rendering engine, and custom themes, styles, and configurations.
Windows Terminal uses Windows PowerShell as the default shell profile when you open the Windows Terminal app.

Select the shell profile (ex: "Windows PowerShell" or "Command Prompt") you want in the Default profile drop menu.
Click/tap on Save at the bottom right.
You can now close the Settings tab or Windows Terminal if you like.
