What Is Riot Vanguard? Is It Safe to Disable at Startup?

What Is Riot Vanguard?

Riot Vanguard is Riot Games' anti-cheat software. On Windows it installs a background service and, on systems that use it, a kernel-level driver to help detect cheating and tampering in supported Riot games such as VALORANT.

The vgc.exe process is the Vanguard user-mode service. If you have Riot games installed, seeing it on your PC is normal. It is not a general Windows component, and it is only there because Riot software installed it.

Is It Safe?

Yes, if it is the real Riot Vanguard from Riot Games. Because anti-cheat tools run with high privileges, you should be more careful than usual about lookalikes.

Check these points:

• In Task Manager, right-click vgc.exe and open its file location.
• Confirm the file is in Riot Vanguard's install folder, not a random temp or user-downloads location.
• Open the file's Properties and check the Digital Signatures tab for Riot Games.

If vgc.exe is running from an unusual folder, has no Riot signature, or appears on a PC that never had Riot software installed, treat it as suspicious and investigate it.

Should I Disable It at Startup?

Usually, no, if you actively play Riot games that require Vanguard. Disabling the Vanguard service can stop those games from launching or cause anti-cheat errors until the service is enabled again.

If you no longer play Riot games, removing Riot Vanguard is the better choice than trying to micromanage its startup behavior. This is not the kind of background item most people need unless they use the related game.

So the practical rule is simple:

• Keep it enabled if you play Riot games that require it.
• Remove it if you do not use those games anymore.

Why Is It Using High CPU or Memory?

Vanguard usually uses little CPU when idle. Short spikes can happen during boot, game launch, game updates, or when Riot software is checking its components.

If usage stays high for a long time:

• Restart the PC and check again.
• Update Riot Client and the game that installed Vanguard.
• Look for failed updates or repeated game launch errors.
• Verify that vgc.exe is the genuine Riot file in the expected install location.

Do not force-end anti-cheat components while a Riot game is running. That can close the game or trigger errors.

How to Disable or Remove It

If you only want to stop it temporarily, use Windows' normal service controls or the Riot software that installed it. Be aware that supported Riot games may refuse to start until Vanguard is enabled again.

If you want it gone, uninstall Riot Vanguard or the Riot game that depends on it from Settings > Apps. That is safer than deleting files manually.

Do not delete random Riot folders or driver files by hand. If uninstall fails, remove the game first, reboot, and then try the uninstall again.

Where Kudu Helps

Kudu can show whether Riot Vanguard is linked to startup or background activity and help you trace related processes. In Performance Monitor, you can see if vgc.exe is actually the process using CPU or memory, and you can compare it with other Riot processes.

On Windows, Startup Manager helps with normal startup entries, but anti-cheat components may rely on services or drivers rather than a simple Run key. If Vanguard appears outside its usual Riot location, Kudu's Malware Scanner can help you check for suspicious persistence or quarantine obvious threats.

If you decide you no longer need Riot software, Kudu's Debloater may help remove supported apps, but use the normal Riot uninstall path first for Vanguard itself.
