I will post this for the benefit of others who might be searching...this can be saved as a shortcut:
C:\Program Files (x86)\OpenVPN Technologies\OpenVPN Client\core\ovpncli.exe -u username -p "super-secret-password" -S +fqdn-of-server connect
The
-p option is not secure, so use with caution! (or omit it to be prompted for auth on the commandline)
