Installing SFTP/SSH Server
On Windows 10 version 1803 and newer
In Settings app, go to Apps > Apps & features > Manage optional features.
Locate “OpenSSH server” feature, expand it, and select Install.
Binaries are installed to %WINDIR%\System32\OpenSSH. Configuration file (sshd_config) and host keys are installed to %ProgramData%\ssh (only after the server is started for the first time).
You may still want to use the following manual installation, if you want to install a newer version of OpenSSH than the one built into Windows 10.
On earlier versions of Windows
Download the latest OpenSSH for Windows binaries (package OpenSSH-Win64.zip or OpenSSH-Win32.zip)
As the Administrator, extract the package to C:\Program Files\OpenSSH
As the Administrator, install sshd and ssh-agent services:
powershell.exe -ExecutionPolicy Bypass -File install-sshd.ps1
Configuring SSH server
Allow incoming connections to SSH server in Windows Firewall:
Either run the following PowerShell command (Windows 8 and 2012 or newer only), as the Administrator:
New-NetFirewallRule -Name sshd -DisplayName ‘OpenSSH SSH Server‘ -Enabled True -Direction Inbound -Protocol TCP -Action Allow -LocalPort 22
or go to Control Panel > System and Security > Windows Firewall1 > Advanced Settings > Inbound Rules and add a new rule for port 22.
Start the service and/or configure automatic start:
Go to Control Panel > System and Security > Administrative Tools and open Services. Locate OpenSSH SSH Server service.
If you want the server to start automatically when your machine is started: Go to Action > Properties. In the Properties dialog, change Startup type to Automatic and confirm.
Start the OpenSSH SSH Server service by clicking the Start the service.
