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.
You make it sound like MS cares about home users at all. MS makes money off business licensing. Forcing businesses to dump old equipment is a big win for them.
It’s not like the people that aren’t upgrading were making them any money anyways. MS doesn’t care about you or the 10’s of people that decide to not upgrade.
Businesses swap hardware every 2-4 years anyway, for support or warranty reasons.
My company shoots for 5 year life on desktops, 3 on laptops. At that mark we evaluate if the machine is still supported and doing the job it needs to do.
If either of those things are not true then we replace the unit.
Smaller companies that I have worked for tried to stretch most hardware to double that, but it was always a bad idea imo.
