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.
From business standpoint, it simply bleeds you potential profits. If tens of percents skimp on two of your OS iterations in a row and keep windows 10 (which most of were “free” upgrades from Win 7 to begin with) then you are losing lot of revenue in a long run. I got the original win 10 upgrade in 2015 (bought win 7 in 2011) , in 2020 build a new PC and still use that licence on it.I possibly see myself using Win 10 well into 2026/2027 when my PC is due for complete replacement. So that is over 15 years period where MS saw no money from me while I still use completely legal version of OS. If there was no TPM requirement, I would probabably already be on Win 11
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.
