Riot Enables On-Demand Vanguard Anti-Cheat for Windows 11 Players

TL;DR
Riot Games’ Vanguard anti-cheat can now run on-demand instead of always being active, launching only when you play a Riot title. The feature, Vanguard Pre-Check, requires Windows 11 25H2 and security features like TPM 2.0, VBS/HVCI, and IOMMU; about 35% of players already meet these requirements, while the remaining 65% would need to enable Secure Boot/TPM and related settings to use on-demand mode.
