If you're on an old outdated version of Windows, however, you might now have SSH enabled. To double check, launch Command Prompt and type the command SSH. If you see output like that below, you have SSH and connecting will be very easy!

NOTE

You will be prompted to verify the ECDSA key fingerprint, type yes and press enter:
