Error Codes: DRIVER_IRQL_NOT_LESS_OR_EQUAL (vgk.sys) or SYSTEM_SERVICE_EXCEPTION (vgk.sys)

Cause: Conflict with another kernel driver (e.g., antivirus, VPN, or hardware monitoring tools).

Corrupted system files can break the Vgk Driver's ability to load.

If you no longer play Riot Games, you can uninstall the driver entirely.

Alternatively, run this in Command Prompt as Admin:

sc stop vgc
sc delete vgc
del C:\Windows\System32\drivers\vgk.sys

Warning: Do not delete the driver while Riot Games are installed—the game will fail to launch or force a reinstall.
