The VGK driver ( vgk.sys ) is a developed by Riot Games. It acts as the backbone of the Vanguard anti-cheat ecosystem.
Conflict with another kernel driver (e.g., antivirus, VPN, or hardware monitoring tools).
To understand why the VGK driver requires kernel-mode access (specifically, "Ring 0" access), you have to understand the modern landscape of video game cheating.
If you are a system administrator or advanced user, you can analyze the Vgk Driver’s behavior using:
The housing of the VGK driver utilizes a specialized Kevlar fiber matrix. Kevlar is known for its incredible tensile strength-to-weight ratio (far exceeding steel), high impact resistance, and durability [1]. Vgk Driver
Uninstall any Riot game that uses Vanguard, reboot, delete any leftover files in C:\Program Files\Riot Vanguard , and then reinstall the game to get a fresh copy of the anti‑cheat driver.

Cheating software has evolved beyond simple memory modifiers. Modern "cheat providers" design software that boots before Windows or injects itself directly into the OS kernel.
Because the housing is composite, engineers have more flexibility in designing the ergonomic shape of the tool. The VGK driver is often designed to fit comfortably in the hand, minimizing strain and improving grip, even in oily or greasy environments. 4. Durable Internal Mechanisms The VGK driver ( vgk
However, the effectiveness of the VGK driver comes with significant trade-offs that have fueled controversy within the gaming community. Because VGK loads at boot and runs at the kernel level, it has unrestricted access to the entire system. Critics argue that this level of access constitutes a security risk; if the driver itself were to have a vulnerability, it could theoretically be exploited by malicious software to take control of a user's PC. Furthermore, privacy advocates have raised concerns about the potential for data collection. While Riot Games has stated that the driver does not harvest personal data, the mere capability of a kernel-level program to monitor system activity is a source of anxiety for privacy-conscious users. This has led to a philosophical debate: is the integrity of a video game worth compromising the security boundary between software and the operating system?
Modern versions of Vanguard running on Windows 11 strictly require and Secure Boot to be enabled in your motherboard’s BIOS.
Wait for the scan to complete, then type DISM /Online /Cleanup-Image /RestoreHealth and press . Restart your PC. Security and Privacy Concerns
The Vanguard ecosystem is divided into two primary components: To understand why the VGK driver requires kernel-mode
The VGK driver will occasionally block legitimate software if that software uses vulnerable or outdated kernel drivers. This frequently happens with hardware monitoring tools (like older versions of HWMonitor, CoreTemp, or RGB lighting software).
For the moment, though, the VGK driver remains one of the most powerful – and most polarising – tools in the fight against cheaters. It undoubtedly works, keeping Riot’s games remarkably clean compared to many competitors. But that effectiveness comes with a price: potential system instability, deep privacy concerns, and a level of access that many users find uncomfortable.
