Windows VPN Setup from Scratch: Complete Guide to Installing the Client and Enabling Startup

This Windows VPN guide is for first-time setup. The full process is more than “install the client and click connect”: verify the client source, import the subscription, choose a suitable route, confirm that system traffic is using the client, then configure split tunneling and startup. Each step has a clear expected result. If the result differs, troubleshoot that step before changing anything else.

Download the Windows client and verify its source

Download the Windows installer from the client download area in the WeekVPN user panel. Do not use a reposted page found in search results, and do not treat an installer sent by another user as an official source. The client handles subscription URLs, route information, and system proxy settings, so verifying the source matters more than installing quickly.

The download page may offer the official client or a compatible client that matches the subscription format. The configuration approach is the same: the installer provides the interface and networking core, while the subscription supplies available routes. A client without a subscription usually will not show WeekVPN nodes automatically; a subscription without a compatible client cannot establish a connection.

✅ The download link comes from the WeekVPN user panel or the official client download page.
✅ The installer name matches the platform shown on the download page; choose the Windows version.
✅ If the page publishes file verification details, compare the downloaded file against the stated value.
✅ Close other clients of the same type before installation to prevent multiple programs from changing the system proxy at once.
❌ Do not disable system security protection just because installation is blocked. First verify the file source and review the error message.

What to check during installation

Follow the installation wizard to complete deployment. The installation folder usually does not affect connectivity, but its permissions may affect automatic updates later. If the client includes a virtual network adapter or network service, Windows may request administrator approval; this is common when enabling system-level networking features such as TUN mode. Approve only after confirming the installer’s source, and never grant permissions to a program from an unknown source.

Launch the client manually after installation. You should see the main window, a subscription management entry, and an area for the route list. An empty list does not mean installation failed; it usually means the subscription has not been imported yet. If the program will not open, record the first Windows message and the first client log error, then check for remnants of an older version or interference from security software.

Section check: If the client opens with a complete interface, continue to subscription import. An empty route list is normal before configuration.

Import a subscription link from the user panel

A subscription link is not an ordinary webpage bookmark. It usually lets the client retrieve route names, server addresses, ports, protocol parameters, and update information. Treat it as a private credential: do not publish it in forums, screenshots, or public documents, and do not submit it to online conversion sites.

Sign in to the WeekVPN user panel, find the subscription or client configuration section, and copy the subscription link for the current client. Return to the Windows client, open the “Subscription,” “Config,” or “Profiles” section, choose import from URL, paste the link, and save. Button names vary between clients, but the core action is to create a subscription source and update it.

Copy the complete subscription link from the user panel, making sure no characters are missing from either end.
Open the client’s subscription management page and choose to add a subscription by URL.
Give the subscription a recognizable name without changing any parameters in the link.
Save it, then update the subscription and wait for the route list to be written locally.
Confirm that node names appear in the list before moving on to route selection.

Identify the error type when import fails

“Format not supported” usually means the subscription type does not match the client core. “Request timed out” is more likely to mean that the current network cannot retrieve the subscription. “Unauthorized” may indicate an expired link, an incomplete copy, or an account issue. Do not repeatedly reinstall the client after seeing an error. First determine whether downloading the configuration failed or whether the client cannot parse a configuration that was already downloaded.

If the subscription worked before but routes are no longer updating, try a manual refresh first. Save any local rules in use before refreshing so custom content is not removed when the client overwrites the configuration. If the client records subscription updates, focus on the HTTP status, parsing result, and update time rather than only the red warning on the main screen.

Understand protocols, route types, and connection modes

The client list may include Shadowsocks, VMess, Trojan, VLESS, Hysteria2, or TUIC. These are proxy protocols or transport methods used between the client and server; they are not the same as the traditional VPN settings in Windows. The protocol handles connection and transport, while the route type describes the network path used by the traffic. They should not be confused.

Protocol	Key characteristics	Configuration focus
Shadowsocks	An encrypted proxy protocol supported by a wide range of clients	The encryption method, password, and plugin parameters must match
VMess	Common in clients compatible with Xray or V2Ray configurations	Identity parameters, the transport layer, and system time must be correct
Trojan	Typically establishes connections with TLS	The server name, certificate validation, and transport parameters must not be changed arbitrarily
VLESS	A lightweight protocol often combined with different transport and security layers	Flow control, TLS, and transport settings are supplied together by the subscription
Hysteria2	Based on QUIC, with an emphasis on performance on unstable networks	The current network must allow the relevant UDP traffic
TUIC	Also uses QUIC and UDP for transport	The client core version must be compatible with the server configuration

A direct route connects the client straight to the remote server, keeping the path simple, but the actual experience depends more on the local carrier and international routing. A relay route first connects to an intermediate node and then forwards traffic to the target region, with the goal of improving the entry path. IEPL describes the network transport and path type, not an encryption protocol; it can be used with different client protocols. When a provider labels a route, follow the node description.

System proxy or TUN mode

System proxy mode mainly changes Windows proxy settings. Browsers and applications that follow the system proxy use the client, but programs that create their own connections, ignore the system proxy, or use a specialized network stack may not be affected. TUN mode uses a virtual network interface to handle a broader range of system traffic. It suits situations that require coverage for more desktop applications, but has greater requirements for drivers, permissions, DNS, and routing.

For a first setup, use the client’s default mode to verify the connection. Once the default mode works, switch to TUN based on application needs. This separates an unavailable node from a virtual network adapter problem. If you enable TUN, custom DNS, and complex split tunneling at the same time, it becomes difficult to identify the source of a failure.

Route selection: Start with a route whose location matches your needs and whose protocol is supported by the current client. Test a relay or IEPL route if a direct route is unstable. Do not judge by the node name alone, and do not change the protocol, mode, and DNS at the same time.

Connect to a route and confirm that traffic is using it

Select the target route in the client, connect or set it as the current node, then enable the system proxy or required connection mode. A “Connected” status only means that the client core has started; it does not prove that every application is using the route. Verification should cover the client status, egress address, and actual application behavior.

Before connecting, open a trusted page that checks your egress address and note the current network egress.
Select a route in the client and start the connection. Watch for a handshake, connection status, or traffic record.
Refresh the lookup page and confirm that the egress region matches the selected route’s expected location.
Open the browser or desktop application you actually need to use and check that access works normally.
Disconnect the client and refresh the page again to confirm that the egress returns, ruling out a misleading browser cache result.

If the browser egress changes but a desktop application still uses the original network, first check whether that application ignores the system proxy. You can configure an in-app proxy or, if the client supports it, test TUN mode. If no application changes, check the system proxy switch, whether the client core has started, and whether another networking tool has overridden the proxy settings.

Clear the old DNS cache with a Windows command

After switching routes, the system may continue using cached domain resolution results. Close the relevant applications, open a terminal as administrator, and run:

ipconfig /flushdns

This command only clears the Windows DNS resolution cache. It does not change subscriptions, nodes, or proxy rules. Reopen the browser and test after it completes. If the issue is an unreachable route, incorrect protocol parameters, or an application bypassing the proxy, clearing the cache will not fix it.

Check for DNS leaks and configure split tunneling rules

After connecting to a route, webpage traffic may use a remote egress while DNS queries are still handled by the local network. This is the situation commonly called a DNS leak. It may not prevent pages from loading, but it can cause inconsistent region detection, unexpected resolution results, or expose lookup activity to an unintended resolver. Check both the egress address and the DNS resolvers rather than relying only on the region shown at the top of a page.

If the client offers “Remote DNS,” “Proxy DNS,” or “DNS hijacking,” prefer the default recommended by the subscription or client documentation. In TUN mode, also confirm that DNS traffic is actually entering the virtual interface. Do not stack multiple encrypted DNS, browser secure DNS, and client DNS solutions without a clear reason; the same domain may then be resolved through different paths, making troubleshooting harder.

When to use global, rule-based, or direct mode

Global mode makes the client handle all traffic within its coverage, which is the most direct way to verify a connection, but local websites and LAN services may take a longer path. Rule mode chooses proxy or direct access by domain, address range, or application rule, making it better for everyday use. Direct mode is generally for temporarily stopping proxy forwarding, but the client process may still be running; switching to direct does not mean the client has fully exited.

✅ For the first verification, use simple rules and confirm that the target application connects reliably.
✅ Set local websites, printers, and LAN resources to direct access as needed.
✅ Send international websites and specified desktop applications through proxy routes according to the rules.
✅ After changing rules, start a new connection so an old session does not continue using the previous path.
❌ Do not copy large rule sets from unknown sources, as important domains may be routed incorrectly.

Split tunneling rules are usually matched from top to bottom, so more specific rules should come before general ones. For example, if application, domain, and region rules conflict, the client uses the first matching result. Rule syntax is not identical across different cores; do not paste one client’s configuration text directly into another client.

Enable startup and automatic connection

“Launch at startup” and “connect automatically after launch” are separate settings. The first starts the client when you sign in to Windows; the second determines whether the client restores the previous route, enables the system proxy, or starts TUN. Enabling startup alone may leave you with an open client that is not yet handling traffic.

In the client settings, enable “Start with system” or an option with the same meaning.
As needed, enable “Connect after launch,” “Restore previous state,” or “Automatically enable system proxy.”
Confirm that a working subscription is saved and that a default route or automatic selection strategy is set.
Exit and reopen the client normally to verify the automatic connection logic first.
Sign in to Windows again and check whether the client starts, the route connects, and the egress changes.

If the client setting is enabled but it does not start with Windows, check whether the entry is disabled under Windows “Startup apps.” If standard system proxy mode starts automatically but TUN mode requests permission each time, the issue is more likely related to the virtual adapter service or permissions. Do not bypass the prompt by disabling User Account Control; follow the service installation method provided by the client.

Automatic connection must also account for a network that is not ready yet. After Windows sign-in, wireless or enterprise networks may take additional time to authenticate. Clients with retry support reconnect when the network recovers; others may report an initial connection failure. If manual reconnection then succeeds, the subscription and node are usually fine. Check the client’s startup delay, retry, or reconnect-on-network-change settings instead of importing the subscription again.

Completion criteria: After signing in to Windows again, the client starts, the target route is restored, and the actual application egress matches expectations. All three must be true for the startup setup to be complete.

Troubleshoot common issues in order

The most effective troubleshooting method is to change one variable at a time. First determine whether the subscription can update, then whether the node can establish a connection, and finally check the system proxy, TUN, DNS, and split tunneling. Skipping steps allows multiple errors to obscure one another and makes client configuration issues look like route problems.

Symptom	Check first	Next step
Subscription update fails	Whether the link is complete and the current network can reach the subscription endpoint	Handle timeouts, authorization errors, and format errors separately
All nodes fail to connect	System time, client core, and network restrictions	Switch to a supported protocol and inspect the first core log entry
Browser works, desktop app does not	Whether the application follows the system proxy	Configure an in-app proxy or test TUN mode
Region does not change after connecting	Whether the system proxy is enabled and rules are matching direct access	Temporarily use a simple mode to verify the egress again
Some websites resolve incorrectly	DNS path, cache, and browser secure DNS	Use one DNS approach and clear the old cache
Client is not connected after startup	Startup apps, automatic connection, and permission status	Verify application startup and core connection separately

When reviewing logs, focus first on information near the initial failure. The many retries that follow are usually repeated results of the same issue. You can retain the error type, stage, and route name, but remove subscription links, authentication parameters, and complete configuration content before submitting a ticket or posting publicly.

Client capabilities on Windows, macOS, iOS, Android, and Linux are not identical. Desktop clients usually offer finer controls for the system proxy, TUN, application routing, and logs; mobile platforms are constrained by system network extensions and background policies, and their configuration locations differ. Do not copy screenshots from mobile guides to find Windows buttons. Use the setting names and core logs in the current client version instead.
