Riot Vanguard now checks several Windows security settings before VALORANT starts, and three errors keep coming up on Windows 11 PCs: VAN 9005 (TPM 2.0 / UEFI / VBS), VAN 9002 (Exploit Protection) and VAN 9006 (Windows too old). If you hit one of them, what was actually switched off on your PC?

What Riot Games Support says (pages read on November 11, 2026):
- VAN 9005: enable TPM 2.0, then Secure Boot, then check that Memory Integrity runs (msinfo32 must show Virtualization-based security “Running”); virtualization (VT-x or SVM) may need to be enabled in the BIOS.
- VAN 9002: set the Exploit Protection system settings (CFG, DEP, ASLR, SEHOP, heap integrity) back to “Use default” and remove Riot entries from Program settings.
- VAN 9006: install all Windows updates (Windows 20H1 or later required).
- Riot does not publish a list of affected PCs, and says nothing on these pages about performance with Memory Integrity on.
Questions for players:
- Which code did you get, and which setting was off: TPM, Secure Boot, BIOS virtualization, Memory Integrity, or an Exploit Protection setting?
- Was it a prebuilt PC, a laptop or a custom build (which motherboard brand)? Did you have to update the BIOS?
- Was the Memory Integrity toggle greyed out or blocked by an incompatible driver? Which driver?
- After turning on Memory Integrity, did you notice any FPS change in VALORANT or other games? Please give numbers and settings if you measured them, and say if it is only an impression.
- Did anything else (an overclocking tool, an old tweak guide, a “debloat” script) turn these settings off in the first place?
Please share your Windows 11 version, CPU, motherboard/PC model, the exact VAN code, and what fixed it. Do not share account details or logs publicly.
