How should you choose a Windows VPN? Start by identifying which apps on your PC need their traffic handled, then check split tunneling, recovery from sleep, and how disconnects are handled. A browser opening a webpage only shows that this particular visit worked; it does not prove that games, meeting apps, and background sync use the same route.
This guide turns “hands-on comparison” into checks you can perform yourself: compare traffic-handling methods, note how apps behave, and then verify recovery. It does not provide unverified brand benchmarks or speed rankings. Client versions, your local network, and the destination server all affect results, so testing in your own setup is more useful.
Understand system proxy and traffic handling
Windows clients may show “system proxy,” “global mode,” “rule mode,” and “TUN mode” near one another, but these terms describe different layers. System proxy and TUN mainly determine how traffic enters the client; global and rule modes mainly determine its route after it enters. Confusing these two layers is a common source of compatibility problems.
A system proxy usually provides an entry point for apps that follow the system setting; not every program uses it. Global mode generally sends all traffic that has already entered the proxy core through a designated exit. It does not automatically handle the entire PC. TUN receives traffic that meets routing conditions through a virtual network interface; the actual coverage still depends on the client's routes, exclusions, and DNS settings.
| Setting | What it does | Use case | What to test |
|---|---|---|---|
| System proxy | Lets apps that follow the system setting use a proxy | Web browsing and some desktop tools | Whether the target app follows the system proxy |
| Global mode | Uses one exit for all traffic already being handled | Temporarily checking whether rules are misrouting traffic | Whether the app's traffic enters the client first |
| Split tunneling | Selects proxy, direct, or blocked routes according to rules | Using international websites alongside local services | Which rule matched and the final exit route |
| TUN handling | Processes traffic through a virtual network interface | Apps that do not follow the system proxy | Permissions, routes, DNS, and conflicts with other network tools |
“Global mode is on, but nothing works” does not necessarily mean the route is down. First check the client's connection log to see whether the target app appears. If no traffic is logged, check the handling method before repeatedly switching nodes.
Importing a subscription: check client compatibility first
A subscription link lets a client retrieve nodes and configuration; it is not an installer or an ordinary webpage bookmark. After obtaining a link from the service panel, import it from the subscription or configuration management page in your client. Tools do not all accept the same formats. If an import fails, check the panel instructions first instead of sending the link to an unfamiliar online converter.
Shadowsocks, VMess, Trojan, and VLESS are different proxy protocols; Hysteria2 and TUIC are QUIC-based proxy options. A client can connect only if it supports the protocols and transport settings used by the subscription. A longer list of protocol names does not prove a service is faster; network support for the relevant transports also affects availability.
- Check the Windows client instructions in the service panel and confirm supported configuration formats, retrieval steps, and permission requirements.
- Import the subscription and update it. Check that the node list appears correctly and whether any errors point to format or protocol support.
- Enable one traffic-handling method, select a route, open a commonly used website, and then check the connection log.
- Keep a configuration that works as your baseline. Change one setting at a time afterward so you can tell what caused a difference.
VPNHN supports Windows. Sign in to obtain subscriptions and clients according to your panel permissions. Visit the client page to see what's currently available. Treat subscription links as access credentials. When reporting a problem, hide the complete link, access token, and account details.
How to Test Browsers, Games, and Office Apps
Before testing, close other proxy tools and confirm that your local network is working normally. Keep the same network, target app, and similar usage conditions while comparing system proxy with rule mode, system proxy with global mode, and TUN handling where needed. Avoid changing nodes, DNS, and rules at the same time; otherwise, it is difficult to explain the results.
- ✅ Browser: Open the websites you actually need and complete sign-in and in-page tasks. Seeing the homepage does not prove uploads, playback, or third-party sign-in will work.
- ✅ Games: Check launcher sign-in, resource downloads, and joining a match separately. Different steps may use different connections; a webpage working through a proxy does not prove game traffic is being handled.
- ✅ Office apps: Check joining meetings, voice, screen sharing, cloud uploads, and enterprise single sign-on. Make sure company intranet resources remain accessible.
- ✅ Local services: Check printers, local network shares, and everyday websites. If they are incorrectly sent through a remote exit, devices may disappear or access may fail.
- ❌ Do not draw conclusions from the client's latency probe alone. Its target may differ from the server used by your app, so it cannot replace real in-app testing.
Games and real-time meetings often use UDP, but “UDP supported” is not the whole answer: the local network, proxy protocol, client settings, and remote path all need to work together. For apps with anti-cheat or enterprise security policies, check their terms and administrator requirements. Do not treat one proxy setting as a universal compatibility fix.
Choosing a setup: For primarily web-based use, test system proxy with split tunneling first. If a particular app does not follow the system proxy, check its in-app proxy settings or try TUN handling. On a work PC, follow company network requirements and do not override routes or security settings provided by your organization.
Split tunneling and DNS: troubleshoot apps that only partly work
Split-tunneling rules can select a route based on domain, destination address, process, or other conditions; the available criteria depend on the client core and configuration. Rules usually have a matching order, and a broad rule near the top may override more specific ones. If a website has a problem, first check which rule matched and whether the final route was direct or proxied, then decide whether to make an adjustment.
For example, international work websites can use a proxy as needed, while company intranet resources and local network devices usually need to remain reachable through a local route. However, sign-in services, content delivery, and upload endpoints may use different domains, so adding only the homepage domain may not be enough. Check each failed connection instead of routing all traffic globally to conceal a rules issue.
DNS translates domain names into addresses. Even when a webpage connection goes through a proxy, DNS requests may still use a local route. Whether that counts as a DNS leak depends on your intended resolution policy. Using local DNS for local services according to your rules is not automatically a configuration failure. Browser Secure DNS, app-level resolution, and client DNS handling may also affect one another.
When troubleshooting, record your current DNS settings first, then use client logs and DNS checks to see which resolver is actually in use. If a browser works but a desktop app fails, pay particular attention to differences in their DNS paths. Do not disable security software or install certificates just to pass a check. If you see a certificate warning, first verify the system time, destination domain, and network environment.
Startup, recovery from sleep, and reconnects
“Start with Windows” may only open the interface; it does not necessarily mean the background service is running, the subscription has loaded, or the proxy is connected. Traffic handling that requires administrator privileges may also involve installing a service and granting system authorization. After changing settings, verify them by restarting the PC rather than assuming setup is complete because the app appears in the startup list.
Check the status after restarting, waking from sleep, and switching networks: does the client reconnect, does the target app need to restart, and does the system proxy setting remain in place? If ordinary webpages also stop working after disconnecting the client, first check whether the Windows proxy setting still points to a local proxy that has stopped. Continue troubleshooting the network before resetting all settings.
Reconnect and disconnect protection are different features. The first attempts to restore a connection; the second restricts network access during a disconnection, according to its configuration. Check the client documentation for availability, traffic coverage, and recovery conditions. To verify how a connection behaves when interrupted, use non-sensitive test content rather than relying on the connection icon alone.
Company VPNs, endpoint security tools, and proxy clients may all modify routes and DNS. If they conflict, save the error details and contact your administrator. Do not uninstall enterprise security components just to get a temporary connection.
Routes and plans: choose based on actual PC usage
Route labels also need context. IEPL describes a type of circuit; transit means traffic is forwarded through an intermediate node; direct generally means that it does not pass through an additional relay node operated by that service. These labels alone cannot prove your complete access path or how an app will perform. Home broadband, the access segment, and the destination site can still affect results. Check the panel for the specific route details.
VPNHN offers 110+ countries, 170+ routes, and unlimited devices. Monthly subscriptions are ¥9.9/month for 60GB, ¥18/month for 250GB, and ¥28/month for 500GB. Data resets monthly on the activation date, and the price difference for a mid-cycle upgrade is prorated for the remaining days. Data packages are ¥158/300GB, ¥358/1000GB, and ¥658/3000GB. They expire when used up and never expire by date.
For regular work and everyday browsing, use your panel usage to choose a monthly subscription tier. If you use the service intermittently, compare the data packages. Large updates, cloud sync, and video playback all affect usage; unlimited devices does not mean unlimited data. VPNHN's refund policy allows a full refund with no reason required within 14 days of the first payment. See plan pricing for prices and full details.
Bottom line: A good Windows setup makes it clear which apps are handled, keeps split-tunneling activity visible in the logs, and behaves predictably after a restart. Verify these points before comparing routes and data costs; this is more reliable than choosing by node count or protocol name alone.
