For example, I have a pretty good gaming PC that plays Grand Theft Auto V at 4K and Elden Ring on low settings.
It no longer gets security updates. Microsoft has made the arbitrary policy that this hardware is too old simply because it doesn't have TPM 2.0 Secure Boot, and a certain generation of Intel or AMD CPU. They have decided it should go to a landfill.
Of course, I am more skilled than the average person, so I easily installed a hack to bypass these hardware requirements and get Windows 11 installed anyway. So I get security updates. But it's a matter of principle that I shouldn't have to use a hack.
Also, a lot of these comments are misunderstanding the question. Recall, Copilot, and ads are not the reason most of these people are opting for Mac instead of Windows 11. It's because they cannot install it legitimately at all. Microsoft said you have to buy new hardware, so they're buying new hardware.
