When choosing a Windows VPN, start with what you need it to cover. For browser access to international sites, consider system proxy settings with rule-based routing. For games and apps that ignore system proxy settings, consider TUN mode. For startup, verify that the connection actually works after you sign in—not just that the option is enabled.
This guide offers a reproducible way to compare configurations and make an informed choice. It does not rank speeds without measurements or claim that one mode is always faster. Results depend on the route, client core, app behavior, and local network. Keep the node and target app constant while changing one setting at a time, so route changes aren't mistaken for mode differences.
Windows VPNs: distinguish traffic capture from routing mode
“Global mode” can refer to different settings. In most clients, it means all requests handled by the proxy core use a selected proxy route. It does not mean every connection on your PC is captured. System proxy settings, in-app proxy settings, and a TUN virtual network adapter determine how traffic is captured.
A system proxy provides settings that compatible apps can use. Browsers usually respect them, but games, background services, and command-line tools may not. TUN mode uses a virtual network adapter and routing to capture more IP traffic, and may require administrator privileges or service support. Whether it handles specific traffic still depends on the client and its routing configuration.
| Traffic capture method | Best for | Key limitations | What to test |
|---|---|---|---|
| System proxy | Browsers and desktop apps that follow system settings | Does not confirm that games or background services use the proxy | Visit the target site and check the connection log for the rule and route used |
| In-app proxy | Developer or office apps with configurable proxy settings | Affects only that app; the address or authentication settings may be incorrect | Check that the app settings match the client's listening configuration |
| TUN virtual network adapter | Apps that ignore the system proxy and need network-level traffic capture | May conflict with a corporate VPN, LAN routing, or DNS policies | Check app connectivity, LAN access, and network recovery after quitting |
For everyday use, use rule-based routing; reserve global mode for troubleshooting
Rule-based routing can direct connections according to domain, destination address, or supported process criteria. A common setup sends local services and LAN resources directly, while apps that need international routes use a chosen proxy. Rules are matched in the order set by the client; broad rules placed too early can override more specific ones.
Global mode can help with a quick diagnosis: if a site fails in rule-based mode but works in global mode, check rule matching, rule-set updates, and DNS mapping. This is not a definitive diagnosis, since the two modes may use different routes. Before comparing them, make sure they point to the same node.
Using global mode all the time may route office apps, downloads, or local services through a proxy unnecessarily and use plan traffic. Rule-based routing isn't automatically correct either. A site may rely on separate domains for sign-in, static assets, and APIs. Routing only its homepage can leave the page accessible while sign-in fails.
- ✅ Keep the node fixed, switch between rule-based and global modes, and record the target app's results.
- ✅ Check connection logs for the destination domain, matched rule, and route policy to confirm how traffic was routed.
- ✅ Preserve suitable routes for LAN and essential corporate resources, then test access.
- ❌ Don't assume “global” captures every app, and don't change all rules at once.
How to test browsers, games, and office apps
Browser: test the full workflow, not just whether a page loads
First confirm that the system proxy is enabled. Visit the target site and test sign-in, navigation, and key features. You can use the site's IP lookup to check the route seen by your browser, but it only reflects that browser request. Browser extensions, built-in proxy settings, and secure DNS can produce different results in other apps.
If the browser works but a desktop app doesn't, check whether the app uses the system proxy and whether it has an outdated in-app proxy setting. Don't assume the node is at fault. Close other proxy tools and test again to reduce interference from conflicting ports, routes, or settings.
Games: reaching the account screen doesn't mean gameplay works
A game launcher and the game itself may use different networking components. After signing in, also test updates, matchmaking, and an actual game session. Some games use UDP; the client, selected protocol, server, and route all need to support the required forwarding. Turning on TUN alone can't add missing support.
If you only need proxy support for a particular game, first check the publisher's rules and recommended setup. A general-purpose proxy forwards traffic but can't guarantee lower latency or better performance in every game. Test for disconnects, matchmaking failures, and the actual connection path instead of relying on a web speed test.
Office apps: check corporate VPN and local resources together
A corporate VPN may install dedicated routes, internal DNS, or device access policies. Running it alongside TUN can affect intranet sites, printers, or file shares. Follow your organization's security requirements and don't override corporate routes without permission. If you need both, ask an administrator to confirm the approved configuration.
Office testing should cover video and audio calls, file uploads, internal DNS resolution, and access to LAN devices. A working webpage doesn't mean real-time calls will work. Record the app, traffic capture method, mode, and observed behavior—this is more useful for troubleshooting than simply noting “connected.”
Importing subscriptions and choosing a client: check compatibility first
Windows' built-in VPN settings support specific VPN tunnel types; they can't import arbitrary proxy subscriptions. Proxy subscriptions generally need a compatible client. A subscription link provides nodes or configuration—it isn't a regular webpage that automatically connects when opened in a browser.
A client's name alone doesn't tell you everything it supports; capabilities depend on its core and version. Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC are different proxy protocols, and subscription formats can vary too. Hysteria2 and TUIC use QUIC-based transport; test availability separately if the network restricts UDP. A protocol name alone doesn't prove that a route is more stable.
- Get the client and subscription. The VPNHead Windows client and subscription are available after signing in; you don't need a paid plan to download the client. Find them on the client downloads page.
- Check the import format. Follow the service's client-specific instructions, and don't mix configurations between different cores. If parsing fails, check the format, client version, and whether the content was copied in full.
- Update and choose a node. Confirm that the subscription updated successfully, then choose a node and route policy. Seeing a node in the list doesn't mean it has connected successfully.
- Start with simpler settings. Test your browser with the system proxy first, then enable TUN if an app requires it. Record each change and its result so you can roll it back.
Auto-start: test startup, connectivity, and recovery after a disconnect
“Start with Windows” often means the client launches after you sign in; it doesn't guarantee a connection before the sign-in screen. Background services may also start differently from the graphical client. Before choosing a setup, determine whether you need automatic connection after sign-in or administrator-managed background network access.
The network may not be ready when the client starts. Switching Wi-Fi networks, waking from sleep, or starting a corporate VPN can also change the default route. Test auto-start after reboot and through recovery scenarios; checking the box in your current session isn't enough.
- ✅ Enable client auto-start, sign in to Windows again, and confirm that the process starts, the subscription loads, and the node connects.
- ✅ Check that the previous node, routing mode, and traffic capture method are restored as expected.
- ✅ After waking from sleep or switching networks, retest the target app instead of relying on the system tray icon.
- ✅ Quit the client normally, then check that the system proxy is restored and regular websites still load.
- ❌ Don't run multiple clients that compete for the system proxy or virtual network adapter routes.
If no websites work after you quit, first check whether the system is still pointing to a stopped local proxy, then review other network settings. If TUN won't start, check permissions, services, and driver status. Don't disable system protections as a substitute for troubleshooting. If you're unsure about a setting, revert it and consult the guides or contact support.
DNS and privacy: what to check beyond your exit route
DNS translates domain names into destination addresses. DNS queries and app connections may take different routes, so a changed exit IP doesn't prove that DNS follows the intended path. The client's DNS mode, Windows settings, browser secure DNS, and corporate network policies can all affect resolution.
Before testing, define what you expect: which domains should resolve locally and which should be handled by the proxy. Then check client logs and use a trusted testing tool. Seeing a local resolver isn't necessarily a problem—split tunneling may intentionally send local domains directly. But if queries for sensitive destinations don't follow the expected policy, review the configuration.
Some clients use Fake-IP, mapping domain names to synthetic addresses that the proxy core associates with the real requests. These aren't actual service addresses or proxy exit addresses. If an app has compatibility issues, follow the client's instructions to exclude the relevant domains instead of copying settings from another platform. Windows virtual adapter and auto-start behavior also can't be applied directly to mobile platforms.
VPNHead describes its privacy policy as “anonymous, no logs.” This is a statement about the service's policy; it doesn't remove risks from browser sign-in sessions, website cookies, or local malware. Client-side diagnostic logs and server logging policies are separate matters too. Remove credentials and unnecessary personal information before sharing troubleshooting records.
Choosing routes and plans to fit your needs
IEPL dedicated routes, relayed routes, and direct connections describe how a route is organized, not the client's routing mode. A direct connection typically connects your local network straight to a node; a relay forwards traffic from an entry point to a later exit; IEPL usually refers to a dedicated segment within the route. These labels alone don't prove the full path or real-world performance, and can't replace testing your apps during peak hours.
VPNHead offers 110+ countries, 250+ routes, and unlimited simultaneous devices. Choose a route that meets the destination requirements of your target service, then test whether the app works. Coverage indicates available choices; it doesn't mean every route works with every site. See the network page for route details.
For ongoing use, compare monthly plans: ¥9.9 / 60GB, ¥18 / 250GB, and ¥28 / 500GB. Monthly data resets on the activation date each month; mid-cycle upgrades are prorated by the remaining days. If your usage varies, compare the data packs, which remain valid until used up and never expire: ¥158 / 300GB, ¥358 / 1000GB, and ¥658 / 3000GB. The two billing options can't be compared by listed price alone.
Bottom line: For browsers and typical desktop apps, start with the system proxy and rule-based routing; test TUN only if an app bypasses the proxy. Use global mode to help diagnose routing issues, and test auto-start by signing in again and checking network recovery. What matters is that your target apps work end to end, LAN access isn't unexpectedly affected, and settings are restored after you quit—not the mode name or route label.
