OpenSSH configuration files
OpenSSH has configuration files for both server and client settings. OpenSSH is open-source and is added to Windows Server and Windows Client operating systems, starting with Windows Server 2019 and Windows 10 (build 1809).

Client configuration files and can be found on the ssh_config manual page and for OpenSSH Server configuration files can be found on the sshd_config manual page. Further Windows-specific OpenSSH Server configuration is detailed in OpenSSH Server configuration for Windows.
In Windows, the OpenSSH Client (ssh) reads configuration data from a configuration file in the following order:
- By launching ssh.exe with the -F parameter, specifying a path to a configuration file and an entry name from that file.
- A user’s configuration file at %userprofile%\.ssh\config.
- The system-wide configuration file at %programdata%\ssh\ssh_config.
Open SSH Server (sshd) reads configuration data from %programdata%\ssh\sshd_config by default, or a different configuration file may be specified by launching sshd.exe with the -f parameter. If the file is absent, sshd generates one with the default configuration when the service is started.
