Valorant, the popular online multiplayer first-person shooter game, uses Vanguard, a top-notch anti-cheat security software that comes bundled with Riot games installation. However, Vanguard requires the system to run on a trusted platform, specifically TPM and secure boot, which are the two essential system requirements to play Valorant.
If you’re using Windows 11, then TPM 2.0 and secure boot would’ve already been enabled on your system. Despite this, some users encounter an “Unsupported Operating system” error while attempting to play Valorant on their Windows 11 desktop. In this guide, we’ll show you how to fix it.
