Extract contents of the latest build to
C:\Program Files\OpenSSH
-
Start Windows Powershell as Administrator
-
Navigate to the OpenSSH directory
cd 'C:\Program Files\OpenSSH'

Only when you migrate from releases before 1.0.0.0:
- To use existing customized sshd_config, you need to copy it from binary location to %programdata%\ssh\sshd_config (Note that %programdata% is a hidden directory).
- To use existing host keys, you need to copy them from binary location to %programdata%\ssh\
- Prior versions required SSHD resources (sshd_config, host keys and authorized_keys) to have READ access to "NT Service\SSHD". This is no longer a requirement and the corresponding ACL entry should be removed. You may run Powershell.exe -ExecutionPolicy Bypass -Command '. .\FixHostFilePermissions.ps1 -Confirm:$false' (Note the first "." is a call operator.) to fix up these permissions.
-
Open the firewall for sshd.exe to allow inbound SSH connections
New-NetFirewallRule -Name sshd -DisplayName 'OpenSSH Server (sshd)' -Service sshd -Enabled True -Direction Inbound -Protocol TCP -Action Allow
Note:
New-NetFirewallRule
is for Windows 2012 and above servers only. If you're on a client desktop machine (like Windows 10) or Windows 2008 R2 and below, try:netsh advfirewall firewall add rule name=sshd dir=in action=allow protocol=TCP service=sshd

Configuring the default ssh shell (optional)
On the server side, configure the default ssh shell in the windows registry.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\OpenSSH\DefaultShell
- Full path (case sensitive) of the shell executable
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\OpenSSH\DefaultShellCommandOption
- The switch that the configured default shell requires to execute a command and immediately exit and return to the calling process. It is used for executing the remote ssh commands. Example- ssh user@ip hostname
If you are configuring the powershell.exe/cmd.exe/WSL-bash.exe as default ssh shell then you can ignore Computer\HKEY_LOCAL_MACHINE\SOFTWARE\OpenSSH\DefaultShellCommandOption
. Your registry should look like this.
If you want to configure default shell (Ex- cygwin) other than powershell/cmd/WSL-bash then your registry should look like this
- Start Windows Powershell as Administrator
