Anything without a TPM 2.0 module on the motherboard.
For example the Lenovo T470 from 2017 doesn’t have it. There are zero other reasons why it, and countless systems around that age and even older, couldn’t run Win 11.
And anything made before October 2014 definitely doesn’t have one, as that is when TPM 2.0 was released in the first place.
[EDIT] Also my gaming PC from 2020 doesn’t currently support Windows 11, because the Asus Prime X570-P motherboard from 2019 doesn’t have one either - it just has a header I could buy (~$20) and slot one in. Scratch that, apparently it does have fTPM support (with a newer bios?).
Huh, apparently yeah, Ryzen processors should have it. I’m guessing it’s disabled by default then.
…or my bios being from 2019 might also have something to do with it :p
