Once you have the VPN connection set up, you can connect by either clicking the Windows key and typing VPN to bring up the Network and Internet page where your VPN connections are listed. You can then click the connect button to begin the connection process. The other option is to click your connection status icon down at the bottom-right of your taskbar, then clicking the VPN of your choice. The VPN window will pop up and as before you can click the VPN you want to connect to and hit the connect button.
