WireGuard with Windows - GUI

Download and install WireGuard Windows Installer

Log in this site.
Enter Config Generator
Click on your favorite option.
Click on "Generate".
Download or extract files.

The config file name will be used as interface name, but our Config Generator builds too complex names. So, rename the .conf file you want to use to a friendly interface name, e.g. from AirVPN_BE-Brussels_Columba_UDP-1637.conf to wg.conf

Launch WireGuard. In "Tunnels" tab, click "Import tunnel(s) from file", pick your .conf files

Click "Activate"
