I don't know if anyone's still running a Pentium III, or any CPU without SSE2, but those devices will no longer get updates from Microsoft. And Microsoft dropped support in a bit of a devious manner, pointing out IMHO that Microsoft is like many other big corporations, and *Only* interested in exec bonuses 1st, what's good for the corp. 2nd, and clients & customers, not really at all.
I'd think that this also puts winXP ahead of win7 on old hardware -- at least with the registry hack, identifying XP devices as embedded, XP still gets security updates, while trying to update 7 manually will only get you a BSOD. And for those running effected devices, all the Microsoft hype up till now about upgrading from XP was a lie, as were their promises of support until 2020.
If you're not effected, you still gotta wonder what's next. Microsoft already arbitrarily disabled updates on win7 for newer CPUs. Intel, which is as concerned about customers as Microsoft, if not less so, is already fading support of low end chips sold just last year, so are those next on Microsoft's Windows chopping block? Microsoft already created an exception to the mandatory win10 version upgrades for one class of devices that they'll no longer support -- what's next?
