Windows Settings Checklist: Verified Visual Proof to Clear Vanguard Van 57
If configuring the service produces a persistent error code 1, software interference runs deeper than a single program. Running a clean boot isolates rogue background processes that target kernel services.
Open the Run menu, type msconfig, and press Enter. Navigate to the Services tab. Crucially, check the box labeled Hide all Microsoft services. This step prevents you from disabling critical Windows operating features. From the remaining list, uncheck every third-party service except vgc. Navigate to the Startup tab, open Task Manager, disable non-essential startup tasks, and reboot your PC.
If the client still refuses to establish a stable connection, reinstall Vanguard completely. Right-click the Vanguard notification icon in the system tray and select Exit Vanguard. Open Installed Apps in Windows Settings, locate Riot Vanguard, and select Uninstall.
Navigate to C:\Program Files and confirm the Riot Vanguard folder is gone. If leftovers remain, delete the directory manually. Finally, launch the Riot Client. The launcher will detect the missing anti-cheat suite, display an "Update" button, and download a fresh, uncorrupted copy of the driver package. Complete the mandatory system restart to finalize the installation.
