Plus individual screen dpi scaling from whenever that was. And the usb handling from win10. Oh and the audio device switcher is so much better in w10 than w7.

Actually people seem to focus a lot on UX but in terms of the core features (handling my hardware and managing processes) windows has improved a lot. I also fondly remember win2k but I think it would be absolutely awful to use now.

The new win 10 audio swapping is a horrible abomination. The capstone being the removal of audio settings from the system tray. I feel like I could rant for an hour on the topic. The per app sound controller is good when it works, but frequently likes to jump to other devices with something resembling free will.

fair points, which i was going to mention, but was feeling too wistful. (it does happen)

Personally I prefer non-antialised MS Sans Serif, and turning off antialiasing is one of the first things I do (but they seem to make it harder with each new version to eradicate it completely) because it physically hurts my eyes and makes me feel dizzy after looking at "smoothed" text for too long. But I think the gradual loss of customisability is definitely something we can all agree against. (For another one, I don't think I've ever put the taskbar anywhere other than the bottom, but I definitely think it would be better if people were free to put it where they wanted.)
