how do you open prompt?

right-click Start works too. Terminal is on that menu, Terminal (Admin) if you need it elevated.

command prompt on windows? press Windows + R, type cmd, enter. or just type cmd in the start search and pick Run as administrator if you need it. if you meant somewhere to type a prompt for chatgpt, that's just the message box at the bottom of the chat, nothing to open. which one were you after?
