It's probably easier and more likely that software crackers will patch out the TPM requirement and make pirate versions of Windows 11 that install without it.

It's probably easier and more likely that software crackers will patch out the TPM requirement and make pirate versions of Windows 11 that install without it. Emulating a TPM at the hardware level is possible but too much work when you can just buy the chips themselves--they aren't some magic unobtanium locked down thing, for example: https://www.digikey.com/catalog/en/partgroup/trusted-platform-module-tpm-add-on-boards-for-raspberry-pi/86878 https://www.digikey.com/catalog/en/partgroup/trusted-platfor... The problem is to get an old system to use it you'd have to also modify its bios to make it aware of the TPM (and figure out how to get access to the phsyical bus the TPM needs to interface with the motherboard). There is a lot of reverse engineering and work to do that sort of thing.

  Where do the keys get strored? Flash in the CPU? UEFI variables? A second flash chip on the motherboard?

    it depends amd mostly uses its psp (platform security processor) of course security depends on amd's enclave. it basically uses ARM TrustZone, microsoft explained it in a paper: https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/msr-tr-2015-84.pdf https://www.microsoft.com/en-us/research/wp-content/uploads/... so the internal storage is eMMC with RPMB and a hardware fuse
