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.
As I recall it, and correct me if I am wrong; but Linux and Distros are given keys to use? So if they want to they can revoke those keys and you could only install a Windows operating system?
