When Microsoft made Windows 10, they examined their testing/QA team : it was HUGE.
Since then , they shrunk it - users are now beta testers, and new versions of Windows 10 were known for how unstable they were. And, that's because Windows 10 supported pretty much any computer that could run Windows 7 - that's almost 15 years of hardware evolution to test against.
And that's costly if you want to test internally, and will cause userspace breakages aplenty with your customers.
So, when they made Windows 11, they decided to cut it all off : nothing older than 5 years will be supported, PERIOD - 64-bit mode only, AVX2 required, TPM 2.0 and UEFI to remove 35 years of BIOS hackery...
Nobody argues with Microsoft not supporting older hardware.
Quite a few people have issues with Microsoft sabotageing older hardware.
The first is a notice on installation/upgrade saying "your hardware is not supported by this edition of Windows: operate under your own risk." which then lets you do it anyway.
If it breaks or fails to work afterwards, they even have the roll-back figured out pretty well.
Currently they won't let you continue even if it's quite obviously not an issue of it working.
Nobody and nothing needs TPM, not even if you wanted to encrypt your storage. And as far as the instruction set is concerned, they only just raised that to Nehalem and younger. And Windows 10 device drivers just continue to work on Windows 11, it's not like there was actually any additional effort involved, except closing the loopholes during installation...
I've tried quite a few systems now as far back as Ivy Bridge with Windows 11 24H2. That i7-3770 with 32GB of RAM and a GTX 980ti is still running quite a few games very competently, I might add, some even at 4k.
And there is simply no chance Firefox, Thunderbird, LibreOffice or VLC might overwhelm it for the next few years, which is all quite a few people ever need from their personal computers.
I'm readying a few of my older machines for parents, in-laws and others around 80 years of age. A lot of them have used PCs for decades and prefer proper keyboards, big screens and things looking and behaving pretty much the same as they did 10 or 20 years ago. And I'm mostly replacing even older systems I handed them 5 or 10 years ago, after I had used them for 5 years.
They don't need ultra thin laptops with odd keyboards or let alone an AI. Nor do they spend all day glued to screens gaming. They just need to manage their digital essentials.
At the same time they are a favorite target of criminals, who want to cheat them out of their last pennies, so they need systems that aren't vulnerable to the outside or so smart that any kid can talk them into being disloyal to their owners.
And they don't need to be spied on or manipulated either, which is very dear to M$ but the last thing they need.
