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.
Sure, it’s much better than it has been a few years ago.
But it’s still not nearly at the point where I would blindly recommend it to non-technical people and call it easy. There’s still a way to go.
On the other hand I have no problem recommending Linux to the typical “I only use an OS to run a browser” user. That wasn’t the case 5 or 10 years ago.
