We use refurbished HP Xeon Workstations, Z240s, etc. and they only support TPM 1.2 and cannot be upgraded to TPM 2.0 according the what I can learn from HP's online support. Unless I am missing something, our machines will not run Windows 11. It seems this will occur with many people using refurbished machines. So odd.

Chances are those CPUs have the Intel PTT which is a fully compliant TPM 2.0 module running in the Intel Management Engine firmware. AMD has a similar feature called fTPM. You should be able to enable that in the BIOS/UEFI. If there's no BIOS setting for that you may be out of luck unless HP releases an update.

Unless I’m mistaken, what I’ve read is that Win11 actually supports TPM 1.2 but they’re saying that to be “logo certified”, new machines must come with TPM 2.0 Edit: apparently that was true but now they’re backpedaling and saying “TPM 2.0 is a hard requirement”, thank you for the reply

  No, they retracted that soft floor. Currently: TPM 2.0 is mandatory. AND Intel CPUs >=8th gen OR >=Zen+. Microsoft announced that they'll publish a post soon with the reasoning behind all that.

    Hm. Fair enough. So it hard requires 2.0 now

    Won't the reason be SafetyNet certification for Android DRM?

      The TPM part maybe, but why the 8th gen intel & zen+ and newer requirement?

        No idea about the CPUs.
