When it comes to using a VPN on your Windows 10 device, the most popular port used is generally VPN Protocols: 443. This is because most VPNs use this port for secure encrypted communication.

However, there are other ports used by VPNs, and other applications that may need to use the same port. So if you are using a VPN and are having trouble connecting, make sure that the port you are using is not in use by another application or service.
