Or maybe they will launch Win 12 with optional TPM support.
Imho making the OS(es) TPM only cannot be good for their business, many people are still on Win 10 with no intention to switch, since their motheboard does not support TPM and do not want to upgrade PC / waste PCI-E slot on TPM extension.
I have a dual GPU laptop with an AMD base and an Nvidia GPU.
Hasn’t been a problem at all (though it certainly was when I tried a year and a half ago)
