    Can’t you load your own keys into your BIOS, letting you sign whatever you want anyway?

      You can, but most everything that would let you run your own boot-time code is supposed to end up in the TPM event log, which the TPM is happy to attest to with its unique/uniquely bannable attestation key. Not too difficult to set it up so that no attestation = no access.

      This type of attestation is far from perfect for a lot of different reasons, and it would be really impractical to automate bans with it, but I guess it’s a tool they see value in.

        So long story short, the anti-cheat software can detect if you’re using a different signing key?

          Yep. It would be incredibly bad if they did automatic bans for any key they don’t recognize, but it’s technically possible.

          Edit: from what I’m reading it apparently just refuses to let you in with unrecognized/non-MS keys. Yeah that makes a lot more sense.
