Not to mention, up until a few years ago, most PCs did not come with TPMs, so they can't run Windows 11. And Windows 10 won't get security patches after 2025.

I built my computer in 2017, and it's still very capable of running modern games, and in three years it will still be perfectly fine. But I won't be able to run Windows 11 unless I do weird hacks and workarounds, or try to source a TPM that works with my motherboard.
