Windows 11 requires Trusted Platform Module (TPM) 2.0, which has caused some problems for PC builders whose hardware is several years old. However, TPM’s impact could extend beyond Windows Hello and Bitlocker, with some game developers using it to enhance anti-cheat software.
The news comes from the Twitter Anti-Cheat Police Department, which gathers news (and a healthy amount of memes) about the latest anti-cheat advancements in the game. Users who installed Windows 11 received an error message at launch Valuable, which states that Vanguard anti-cheat software “requires TPM version 2.0 and secure boot enabled to play.”

Tweets backed up by some user reports on Reddit, especially in relation to Valuable substance technical support. While we’re not sure how developer Riot Games is using TPM and Secure Boot, it looks like both will lead to a new era of anti-cheat measures on Windows 11. Themes Hardware fraud prevention has been speculated since the announcement of Windows 11 and it looks like it could be here.
However, it probably won’t work the way you might suspect. Anti-cheat software is designed to be sophisticated, but in short, it ensures that everything running in a game works as it should. That means the code is done, the inputs are correct and respond the way they should, and without any extra programs running that could interfere with the game.
TPM doesn’t change that. If you don’t know, the TPM is a small processor that sits on your motherboard and acts as a secure data store. You don’t store actual data on it, but things like keys and certificates that can be used to authenticate you or decrypt data you’ve secured elsewhere.
That functionality has a direct implication for anti-fraud software: Hardware ID (HWID) ban. At the most basic level, the HWID ban blocks the router’s MAC address – a hard-coded unique address in your router. However, developers can also repeat other identifiers, such as a combination of components or your network configuration, and use them all for a ban.
HWID bans can easily happen and that’s where TPM comes into play. TPM and Secure Boot validate the first files loaded on your computer to remove any malware that executes before the operating system loads. It basically ensures that the PC has all the necessary software and is running all the necessary software.
By exploiting that through anti-cheat, developers can enforce stronger HWID bans. This is speculation right now – Riot has yet to clarify how Vanguard’s anti-cheat TPM is used, and it likely won’t avoid people exploiting it. However, verifying the hardware and using it to enforce the HWID ban seems to be the most practical way to use TPM and Secure Boot.
This requirement only applies to Windows 11, requires TPM 2.0 and Secure Boot. Many users without these features will continue to use Windows 10 until Microsoft ends support in 2025, although we’re not sure if Riot will push the requirement back on the older OS. .
