I found a great news that Windows 10 officially supports SSH server, but that is not basically enabled. In order to enable SSH server, you will need to follow following procedure

STEP 1. Move to Manage Optional Features

Windows → Settings → Apps and Features → Manage Optional Features

STEP 2. Install OpenSSH Server

STEP 3. Enable OpenSSH Server when booting

Windows → type "Services"

Toggle OpenSSH Server Manual → Automatic

Now you can connect to your server by ssh/sftp enabled terminal.
