Connect OpenVPN on Windows startup.
Adding the following parameter to the "Destination" in a shortcut to opennvpn-gui.exe will make it automatically connect to myprofile.ovpn on startup, and show the classic GUI icon.:
"C:\Program Files\OpenVPN\bin\openvpn-gui.exe" --connect myprofile.ovpn
Place this shortcut in the All Users Startup Folder
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
if you wish all users should use VPN. If only a certain user shall auto connect then place the shortcut in
C:\Users\[Username]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
NOTE: the myprofile.ovpn file must be available in the folder
C:\Users\[Username]\OpenVPN\config\
