Does Riot Vanguard not work on Windows 11?
Interestingly, the basic security requirements for both Vanguard and Windows 11 are the same – TPM 2.0 and Secure Boot. However, Vanguard needs additional resources like a sufficiently powerful CPU and GPU. Once these conditions are fulfilled, Valorant will work well on your Windows 11 system. However, a lot of users install Windows 11 on older computers by evading the requirements. That is the reason they encounter errors like VAN 9003.
