Why does a Valorant Unsupported Operating System error occur on Windows 10?

“Unsupported Operating System” errors are typically caused by problems with Vanguard, Valorant’s anti-cheat system, when it encounters compatibility issues with certain components of Windows 10.

The Valorant game uses Vanguard to ensure fair gameplay and prevent cheating. However, the system relies on deep integration with the operating system, making it susceptible to changes.

This error may occur on Windows 10 due to the following reasons:

Outdated Windows 10 Version

As part of Valorant’s Vanguard anti-cheat system, certain features and security updates are found in the latest versions of Windows 10.

If your operating system is outdated and lacks these required components, Vanguard may not function correctly, resulting in the error “Unsupported Operating System”.

The developers of Valorant, Riot Games, regularly update their games and their anti-cheat systems to adapt to the changing Windows environment, which is why it is imperative to have the most up-to-date version of Windows 10.

Third-Party Software Conflicts

By operating at the kernel level, Vanguard has deep access to your computer’s resources in order to detect and prevent cheating. In some cases, this level of access can conflict with third-party software or drivers that are also operating at a low level.

In some cases, antivirus software, system optimization software, or virtualization software may interfere with Vanguard, causing the error message “Unsupported Operating System”.

Windows Update Issues

Sometimes, Windows updates fail to install correctly, or there may be pending updates that have not been applied.

There are several issues that can cause inconsistencies in the system, resulting in Vanguard’s incompatibility.

Corrupted Game Files

Corruption of Valorant’s game files can also cause the “Unsupported Operating System” error to appear. It may occur during installation while updating or as a result of an unexpected system crash.Fix Valorant Unsupported Operating System Windows 10
