Checkout whatever you can find out from Microsoft about connecting to Windows using Windows OpenSSH and Hello. You may have to use SSH as intended: add your host key to remote {~/.ssh,/etc/ssh}/known_hosts; and your public key to remote ~/.ssh/authorized_keys{,2}; locally do the equivalent of eval `ssh-agent` and ssh-add ~/.ssh/id_...; then use your client to connect. -- Take care.
