If you want a VPN at its fullest, run it on Windows. This is the platform providers build out first and most completely — the Windows app is almost always the reference version, with every feature switched on while phones and tellies get a trimmed-down cut. Split tunnelling, a proper kill switch, the full menu of protocols, auto-connect the moment you touch an untrusted Wi-Fi network: on Windows you get the lot. Our top Windows app is NordVPN — fastest in our 2026 testing, with NordLynx, split tunnelling and a kill switch that all behave exactly as they should on a Windows 10 or 11 desktop.
ExpressVPN is the close second: the most polished Windows client in the category, with the fast Lightway protocol and a kill switch (Network Lock) that simply does not leak. Surfshark is the value and whole-house pick thanks to unlimited simultaneous devices, then Proton VPN, IPVanish and CyberGhost round out a top six. Every one ships a Windows kill switch and split tunnelling — which is exactly why a real provider app beats the VPN client Windows already has built in. This guide is about getting the most out of the most capable VPN platform there is.
Windows gets the fullest apps — and that is the whole point
Across every VPN we rate, the Windows app is the one with the most under the bonnet. It is not a coincidence: Windows is the biggest desktop platform, developers build for it first, and the OS imposes none of the restrictions that thin out the iPhone or smart-TV versions. So the Windows client tends to be the complete app — the one every other platform is a subset of.
In practice that means a feature list the mobile apps can only envy: split tunnelling (route chosen apps outside the tunnel), a hard kill switch, the full choice of protocols — WireGuard or NordLynx for speed, OpenVPN for reach, sometimes Lightway or a stealth mode on top — and auto-connect rules that fire on untrusted networks. None of it is bolted on; it is all in the desktop app by default, on both Windows 10 and Windows 11.
That completeness is why this page sits apart from our other device guides. A VPN on a Mac leans on the native, Apple-silicon-tuned app; on Android the trick is the OS-level always-on toggle. On Windows the story is simply depth. Our platform-agnostic best VPN for Ireland ranking covers the wider picture.
The Windows edge in one line: it gets the most feature-complete app of any platform — split tunnelling, a real kill switch, every protocol and auto-connect, all in the desktop client on Windows 10 and 11.
Split tunnelling — the feature you will actually reach for
Split tunnelling lets you decide, app by app, which programs run through the VPN tunnel and which use your normal connection. It is one of the features that is fullest on Windows, and once set up it quietly solves a handful of everyday annoyances.
The classic Irish case is your banking. AIB, Bank of Ireland and Revolut can get jumpy about a login from a "foreign" VPN IP, throwing extra verification or blocking the session. Route the bank app — or its browser tab — outside the tunnel and it sees your real Irish IP, while everything else stays protected. The same trick keeps a download manager or a big game update on your raw line at full speed, or a local printer and network drive reachable while the rest of your traffic is encrypted.
On Windows the app list is granular and it survives reconnects, which is why we weight it in the ranking. Every provider in our top six supports split tunnelling on Windows — NordVPN and ExpressVPN have the cleanest implementations on the desktop.
Use split tunnelling to keep your Irish bank app on your real IP — no "foreign login" flags — while the rest of Windows runs through the VPN. It is the desktop feature you will keep going back to.
The features that matter — kill switch, protocols, auto-connect
Beyond split tunnelling, three things define a good Windows VPN app, and all three are present on every pick in our top six.
The kill switch
A kill switch is the one to switch on the day you install. If the VPN drops for any reason — a server hiccup, a flaky Wi-Fi handover, a sleep-and-wake — it blocks all internet traffic until the tunnel is back, so your real IP never escapes during the gap. ExpressVPN brands it Network Lock; NordVPN gives you both an app-level and a system-wide version. Without it, a momentary drop quietly exposes you.
Protocol choice
Windows apps give you the full menu of protocols. WireGuard — or the providers’ own builds, NordLynx and Lightway — is the modern default: fast, lean and right for almost everyone. OpenVPN is the slower, rock-solid fallback that punches through awkward networks, and several apps add a stealth mode for restrictive Wi-Fi. You rarely need to touch this, but Windows is where the full choice lives.
Auto-connect
Auto-connect is set-and-forget. Tell the app to launch with Windows and connect automatically — and, crucially, to fire the moment you join any network it does not recognise. So your laptop is protected on hotel, café and airport Wi-Fi without you pressing a button. With the kill switch, the tunnel is up before any app sends a packet.
The three to enable on day one: the kill switch (blocks traffic if the VPN drops), a WireGuard-based protocol (NordLynx/Lightway, for speed) and auto-connect on untrusted Wi-Fi. All three ship on every pick here.
Windows already has a built-in VPN — why an app still wins
Windows 10 and 11 ship with their own VPN client, tucked away in Settings › Network & internet › VPN. You can add a connection there and Windows will dutifully build the tunnel. So why bother with a provider app? Because the built-in client is a bare protocol connector, not a VPN service — and the gap is enormous.
It is manual configuration only. No server list, no map, no one-tap connect — you type in a server address and credentials by hand for every location, and Windows has no servers of its own, so you would still need a subscription to point it at. More importantly it has no kill switch, no usable split tunnelling, no auto-connect and no WireGuard-based protocol. If the connection drops, Windows carries on over your normal line and leaks your real IP — the exact failure a kill switch exists to prevent.
So the built-in client is fine to know about, but for anyone not hand-rolling a corporate setup it is the wrong tool. A provider app gives you the servers, one-click connect, kill switch, split tunnelling, protocols and auto-connect — the whole feature set this page is about — for the price of a download.
Windows’ built-in VPN is manual-config only: no servers, no kill switch, no split tunnelling, no WireGuard. A provider app gives you all of that in one click — it wins every time for normal use.
How we ranked the VPNs for Windows
Because Windows apps are so feature-complete, the ranking is less about which features exist — they nearly all do — and more about how well each app uses the platform. We weighed four things:
- Speed in our 2026 tests. Windows is where you do the heavy lifting — big downloads, 4K streaming, gaming — so raw throughput matters. NordVPN came out fastest, a large part of why it tops this list.
- How cleanly the core features work. The kill switch must not leak, split tunnelling must survive reconnects, auto-connect must actually fire on new networks. We tested each on Windows 11, not just off a spec sheet.
- App polish on the desktop. A good Windows app is powerful and easy — deep controls there when you want them, out of the way when you do not. ExpressVPN sets the bar.
- Value and devices. Per-month price on the longer plans, and how many devices one subscription covers — the reason Surfshark and IPVanish climb for a multi-machine household.
Every pick clears the essentials: all six have a Windows kill switch and split tunnelling, all run on Windows 10 and 11, and all are providers we trust on logging. The order below reflects how they perform in use, not just what the box promises.
Our top picks for Windows
NordVPN — fastest, and the full feature set done right
Our number one. It was the fastest VPN in our 2026 tests, and NordLynx keeps it that way for downloads, 4K streaming and gaming. The Windows app has everything switched on — split tunnelling, both an app-level and a system-wide kill switch, auto-connect on untrusted Wi-Fi — with 50+ Irish servers and the deepest audit trail in the category. The full NordVPN review has the detail; for most Windows users it is the obvious pick.
ExpressVPN — the most polished Windows app
A very close second, and the choice if app quality is everything. The Windows client is the slickest in the category — powerful but effortless — with the fast Lightway protocol, dependable split tunnelling and a kill switch (Network Lock) that does not leak. It unblocks RTÉ Player and Netflix without fuss. The catch is that it costs a little more; the ExpressVPN review weighs it up.
Surfshark — best value, unlimited devices for the whole house
The household pick. Budget pricing on the longer plan, a genuine Dublin server, reliable streaming — and the clincher, unlimited simultaneous devices, so one subscription covers every machine, laptop and phone under the roof. The Windows app carries the full kit, split tunnelling and kill switch included; the Surfshark review covers the caveats, chiefly switching auto-renewal off after the intro term.
Proton VPN, IPVanish and CyberGhost — the rest of a strong six
Proton VPN is the privacy specialist — Swiss-based, open-source apps, a full-featured Windows client and a usable free tier. IPVanish, like Surfshark, runs unlimited simultaneous devices with fast WireGuard speeds, a fair fit for a busy household. CyberGhost completes the six with a beginner-friendly Windows app, a huge server network and a market-leading 45-day money-back guarantee — the longest no-quibble window here, and a reason it is an easy one to try first.
