About this tag
The vanguard on-demand tag covers Riot Games’ change to its Windows anti-cheat system, which can load the Vanguard kernel driver only when supported games require it rather than at startup. Coverage focuses on the balance between reduced always-on operation and continued kernel-level protection for VALORANT and League of Legends. It also explains how the mode is tied to Windows 11 25H2, qualified PCs, hardware-backed security checks, and Microsoft-supported attestation of what entered the kernel before Vanguard loads.
