For Windows users, just as with Linux and macOS, you can now access the Mullvad CLI from anywhere in the terminal. Simply open a terminal window, type mullvad , and you’ll see a list of all subcommands, including a few new ones. If you want to report a problem, the universal command is now mullvad-problem-report.
