There is any number of free VPN options you can use for your Windows desktop computers, notebooks, and tables. Windows 10 is, of course, supported, but so are many previous versions of the operating system, including Windows 8 and 7.
Despite other VPN protocols making headway, PPTP is still very commonly used. Its biggest advantage is that it works on nearly every flavor of Windows, be it on your desktop or a tablet.
But, because PPTP makes use of the GRE, it does need an additional TCP port to work. Because so many people forget to allow another port through their firewall, it’s very common to get cryptic connection errors when opting for this VPN protocol.
We’ll be updating this page to talk about the other Windows VPN options very shortly.
