it's not due to some arbitrary cut-off date, it's that windows 11 requires TPM 2.0. It's likely that your PC just either lacks a motherboard that supports a firmware TPM on AMD CPUs, or is just missing a TPM module. Accordingly, I've prevented my system from being auto-upgraded to 11 by just disabling my system's TPM.

It’s not just TPM but a large number of CPUs Microsoft is just unwilling to support.

Yeah I know it's because of TPM. But presumably at some point computer manufacturers added TPM to their motherboard/CPUs to be able to say they have or can upgrade to Windows 11. Not saying there's a definite time cutoff, just generally speaking it seems like somewhere around there more computers started including the TPM capabilities. Still three years isn't that long. I'd hate to have to trash my motherboard and/or CPU just to get security updates.

  A PC from 2021 should have a TPM in the processor.

    Pretty sure it said it was because it didn't have TPM. I'll double check tomorrow.

      Probably the fTPM of your processor is just disabled in the BIOS/UEFI. You can just enable it in case you really want to upgrade.

        Yep, turns out it wasn't enabled in the BIOS. Discovered this myself when I clicked the more info today after getting the 'You don't have TPM on this device' from the Windows PC Health Check. That was really confusing. I definitely thought I didn't even have it on my hardware from its messaging the first time around (and even the second time around I wasn't sure until I went through the instructions and checked all the menus on the BIOS). So if I got confused and thought I didn't have it on my computer, probably many, many other people less tech savvy than me were similarly confused (or just wouldn't bother. BIOS changes can be weird and scary anyway, Windows couldn't even give good instructions on that part because BIOS menus tend to be pretty different).

Not true. I have a PC (Dell OptiPlex 7040 SFF) with TPM 2.0 and a CPU (i7-6700) that's definitely not on the supported CPU list, which, for Intel Core CPUs, seems to literally be "number greater than or equal to 8000". If this is not true, what CPU features do the supported ix-8xxx "Kaby Lake R" and "Kaby Lake G" processors have that the unsupported ix-7xxx "Kaby Lake" processors lack? The fact that the current supported CPU list for Windows 7[1] excludes all fourth generation and earlier Intel Core CPUs leads me to believe that these lists aren't derived from feature requirements alone, unless Windows 7 requires features that first became available with CPUs released in 2014.

It doesn't require tpm as proved by windows 11 iot ltsc not havig that requirement. That version doesn't even have the arbitrary cpu requirement except for needing sse 4.2
