The "Fall Creators update" of Windows 10 adds the option to install a beta release of an ssh client and server (seperate options).
Discussed in various places online, search for "windows 10" and "ssh", but in summary :
Click start button
type "settings"
in settings, go to "apps"
"manage optional features"
"add a feature"
in amongst the mostly optional fonts you'll see "Openssh client" and "Openssh server" - both beta. Click the client, then click "install".
You may need to reboot, but after this you can type ssh id@address in a command prompt and it all works!
