ExpressVPN's Windows app runs on the Lightway protocol, which opens a tunnel in under a second and reconnects cleanly when you move between Wi-Fi and mobile tethering. Servers run on RAM-only TrustedServer hardware across 105 countries, and the client bundles a kill switch, split tunnelling, a DNS leak test and a Smart Location picker that chose the fastest nearby node.
The pre-activated package installs the Lightway driver and the browser extensions in one pass, then applies the licence locally so the 8-device cap and the premium server groups are already active. Nothing in the client phones home for entitlement checks, and the update service can be left enabled or blocked at the firewall.
