To do this, launch a normal Windows command prompt and enter the command “ssh user@*vm_ip*” (1), where “user” is the username that was specified while creating the virtual machine and “*vm_ip*” is the VM IP address.

Then type “Yes” (2) and enter a password (3) that was specified while creating the virtual machine.
