# Services Known to Conflict with WinDivert in Zapret: How to Identify and Fix Them > Identify and resolve WinDivert conflicts with Zapret caused by Adguard Killer networking Intel Check Point VPNs and GoodbyeDPI using service.bat diagnostics. - Repository: [Flowseal/zapret-discord-youtube](https://github.com/Flowseal/zapret-discord-youtube) - Tags: how-to-guide - Published: 2026-05-02 --- **The most common WinDivert conflicts in Zapret come from Adguard, Killer networking software, Intel Connectivity services, Check Point security, SmartByte, VPN clients, and other WinDivert-based bypasses like GoodbyeDPI, all of which can be detected and removed using the built-in `service.bat` diagnostics.** Flowseal/zapret-discord-youtube relies on the WinDivert driver to intercept and modify network packets. When another application installs a competing low-level network filter, the driver cannot bind to the network stack and the bypass fails. The repository includes a diagnostic routine in `service.bat` that automatically checks for these **services known to conflict with WinDivert** and offers to remove them. ## Why WinDivert Conflicts Occur WinDivert operates at the Windows Filtering Platform (WFP) layer. Only one driver can occupy a specific packet-filtering slot at a time. If a security suite, VPN, or network-optimization tool has already registered a hook, `WinDivert64.sys` fails to load. This results in connection errors or silent failures when launching Zapret. ## Specific Services That Block WinDivert The `service.bat` script (lines 53-136 and 564-630) maintains an allowlist of known incompatible services. When you run diagnostics, it checks for the following processes and drivers: ### Adguard (`AdguardSvc.exe`) Detected in `service.bat` at lines 53-60. Adguard’s network filter occupies the same WFP layer WinDivert requires. **Resolution:** Stop and delete the service: ```cmd sc stop AdguardSvc sc delete AdguardSvc ``` Alternatively, uninstall Adguard completely. ### Killer Networking Software (`Killer`) Detected in `service.bat` at lines 63-70. The Killer driver loads a packet-filtering module that prevents WinDivert’s driver registration. **Resolution:** Remove the service: ```cmd sc stop "Killer" sc delete "Killer" ``` ### Intel Connectivity Network Service Detected in `service.bat` at lines 73-80. This Intel utility installs a low-level network filter that clashes with WinDivert. **Resolution:** Stop and delete the service: ```cmd sc stop "Intel Connectivity Network Service" sc delete "Intel Connectivity Network Service" ``` ### Check Point Security (`TracSrvWrapper`, `EPWD`) Detected in `service.bat` at lines 83-99. Check Point products load their own packet-filter drivers that block WinDivert. **Resolution:** Stop and delete the wrapper service: ```cmd sc stop TracSrvWrapper sc delete TracSrvWrapper ``` If the service persists, uninstall the Check Point component from Control Panel. ### SmartByte Detected in `service.bat` at lines 103-110. SmartByte’s network-optimization driver conflicts with WinDivert’s packet interception. **Resolution:** Disable the service: ```cmd sc stop SmartByte sc delete SmartByte ``` ### VPN Clients (Generic) Detected in `service.bat` at lines 119-136. Virtual adapters from VPN software can prevent WinDivert from binding to the network stack. **Resolution:** Shut down all VPN clients and disable virtual adapters: ```cmd netsh interface set interface "OpenVPN" admin=disable ``` Replace `"OpenVPN"` with the actual name of your VPN adapter. ### Other WinDivert-Based Bypasses (GoodbyeDPI, discordfix_zapret, winws1, winws2) Detected in `service.bat` at lines 564-630. These tools also use WinDivert; only one instance can be loaded simultaneously. **Resolution:** Use the *Run Diagnostics* option in `service.bat` to automatically stop and delete these services, or manually run: ```cmd sc stop GoodbyeDPI sc delete GoodbyeDPI ``` ## Automated Detection with service.bat The fastest way to identify conflicts is to use the built-in diagnostics: 1. Run `service.bat` from an elevated command prompt. 2. Select **option 10** (Run Diagnostics). 3. The script checks for every service listed above and prints coloured warnings (e.g., `call :PrintRed "[X] Killer services found. Killer conflicts with zapret"`). 4. When prompted, allow the script to execute `net stop` and `sc delete` commands automatically. If a service cannot be removed automatically because it is protected by its parent application, the script will instruct you to uninstall the software manually via Settings > Apps. ## Manual Resolution Steps If you prefer manual intervention or the automated removal fails, use these standard Windows service commands. Stop and remove a specific conflicting service: ```cmd sc stop "ServiceName" sc delete "ServiceName" ``` Disable a VPN adapter by name: ```cmd netsh interface set interface "AdapterName" admin=disable ``` Verify WinDivert can load after cleanup by checking the `bin/WinDivert64.sys` driver status or simply re-launching `service.bat` and selecting the start option. ## Summary - **WinDivert requires exclusive access** to the Windows Filtering Platform; only one low-level filter can operate at a time. - **Known conflicts** include AdguardSvc.exe, Killer, Intel Connectivity Network Service, Check Point (TracSrvWrapper), SmartByte, VPN clients, and other bypass tools like GoodbyeDPI. - **Detection** is automated via `service.bat` (lines 53-136 and 564-630) using the *Run Diagnostics* menu. - **Resolution** typically involves running `sc stop` followed by `sc delete` for the offending service, or uninstalling the parent application entirely. ## Frequently Asked Questions ### Can I run Zapret with a VPN active? Generally no. VPN clients install virtual network adapters and filtering drivers that occupy the same network layer as WinDivert. You must shut down all VPN services (`sc stop` or disable adapters) before starting Zapret. Some users report success with split-tunneling configurations, but standard operation requires the VPN to be disabled. ### Why does Adguard specifically block WinDivert? Adguard uses the Windows Filtering Platform to inspect HTTPS traffic for ad blocking. Because it registers at the same driver level as WinDivert (as seen in `service.bat` lines 53-60), the two cannot coexist. You must remove or disable Adguard’s service (`AdguardSvc.exe`) to free the WFP slot for Zapret. ### How do I know if a service is conflicting without running diagnostics? Symptoms include immediate connection failures when launching Zapret, error messages about driver installation, or silence in the console logs. The definitive method is to run `service.bat` and select **Run Diagnostics** (option 10), which explicitly checks `service.bat` lines 53-136 for the known conflicting service signatures. ### Is it safe to delete these Windows services? Deleting services like Killer, SmartByte, or Intel Connectivity removes network-optimization features but will not break core Windows networking. Always stop the service first (`sc stop`) to test stability before deleting it (`sc delete`). If you encounter issues, you can reinstall the parent software later. System-critical services cannot be deleted this way, so the command is safe for the third-party applications listed.
