Riot Games has announced that it plans to let players stop its Vanguard anti-cheat from loading at Windows start-up, the company has announced, ending the boot-time behavior the kernel driver has had since 2020. The new mode, Vanguard On-Demand, loads the driver only when a Riot game launches and unloads it on exit, made possible by a Windows 11 25H2 feature that records driver activity even while Vanguard is dormant. It works only on PCs that also have UEFI Secure Boot, TPM 2.0, Virtualization-Based Security (VBS), Hypervisor-Protected Code Integrity (HVCI), and IOMMU switched on. Riot anti-cheat lead Phillip Koskinas said roughly 35% of players already clear that bar, while about 3% are running incompatible hardware.
Riot calls the qualifying checklist Vanguard Pre-Check, and many prebuilt PCs and laptops sold in the past couple of years ship with the features on by default, and Koskinas estimates the share of fully secured machines at 34.33% and rising one to two percentage points a month. Everyone else will need to enable the settings manually, and most are UEFI options that Vanguard can’t change, meaning a trip into BIOS for those who want to do so.
