Windows Built-In VPN client (PPTP)
Windows has a built-in VPN client. Surprised? Many people are.
It’s not a heavily advertised feature, but it covers many people’s needs. Before exploring other client solutions, it’s worth pulling up the quick launch box in the Windows start menu and typing “VPN” to start the configuration process. In Windows versions prior to Windows Vista, the built-in VPN client received a fair amount of criticism for lacking features and supported protocols. Since Vista and especially in the Windows 7 implementation, it’s grown significantly and unless you need a feature or standard that isn’t implemented you may not need to install anything at all.
