The ProtonVPN Windows app project hosts the official open-source client software that lets users securely connect their Windows machines to the ProtonVPN service with full system-wide VPN protection. It includes a modern GUI built with .NET and WPF that lets users authenticate, choose VPN servers, and configure features like split tunneling or kill switch, while a background Windows service manages VPN connections using the OpenVPN protocol and handles networking tasks such as firewall and adapter configuration. The app integrates a custom TAP driver and a split tunnel callout driver to help route traffic securely and prevent leaks, and is structured so the GUI and service components work together to deliver a smooth user experience on Windows desktops and laptops. ProtonVPN’s Windows client supports both free and paid users with access to Proton’s global server network, encrypted tunnels, and privacy-first policies that block logging and respect user anonymity.

4 out of 5 starsThe open-source client app is a plus, but its speeds tend to be slower than those of competitors like NordVPN, ExpressVPN, and Surfshark. Secure Core routes your connection through only three Nordic countries, which makes it too slow for practical use. This may vary by location, though if you live in a European country close to a Secure Core server, the speeds might be decent. The pricing plans also changed between last week and this week, which is confusing. I think it’s one of the best free VPN services, and a lot of people use it. In South Korea, where VPNs are widely used, it ranks around fourth among paid VPN services. - netxhack.com/vpn/
