FWIW TPMs have been in computers (processors) FIR years, but they were often disabled by default by motherboard vendors because they couldn't be arsed to test beyond the bare minimum Windows required.
The move to TPM 2.0 made a lot of TPM-capable systems incompatible. Arbitrary CPU support also didn't help; there is no clear reason why some CPUs made the cut and others didn't. Seems like a mix between fTPM 2.0 support and SPECTRE hardware mitigations, but MS never really clarified what their actual reasons were.
