<#
In order to configure Git to use the "Windows" OpenSSH (found at %SystemRoot%\System32\OpenSSH),
rather than the one packaged with Git for Windows (at %ProgramFiles%\Git\usr\bin) and enable agent forwarding,
set Git's core.sshCommand configuration property "C:\Windows\System32\OpenSSH\ssh.exe" -T (with double-quotes).
#>

# Using environmental variable GIT_SSH_COMMAND:
[Environment]::SetEnvironmentVariable("GIT_SSH_COMMAND", """$((Get-Command ssh).Source)"" -T", [System.EnvironmentVariableTarget]::User)

# - OR -

# Using Git config (global):
git config --global core.sshCommand "'$((Get-Command ssh).Source)' -T"

# Enable and start the ssh-agent service
Get-Service -Name ssh-agent | Set-Service -StartupType Automatic
Start-Service ssh-agent
