The telemetry, ads and forced online accounts are the only major changes since Windows 7 that I can think of. What useful features has Microsoft added since then to make you consider it at its peak currently? I haven't been using it as heavily and I'm genuinely interested if there's something great I've missed.
Night mode (blue light filter) is naitvely supported/builtin Dark theme HDR support Auto HDR for many older games Native system wide support for surround sound in headphones with hrtf Win+Shift+S screenshot tool It took a long time to get here, but the settings app is now better than the old Control Panel imo If you're a gamer then HDR/surround/raytracing can potentially be huge upgrades if your hardware supports it.
Nowadays it's impossible to know exactly where some specific setting is anymore, and the settings app has been so dumbed down that most settings don't even exist anymore. Just the other day i tried to fix my dads touchpad and went on a wild goose chase through every possible setting location, of which there were too many, and kept coming back to the "settings app" in which the touchpad "settings" had only a single checkbox, fully unrelated to anything actually useful at all. The tab was there but there was no fucking settings in it. Nothing useful at all. In the end i tried driver updates, i tried rollbacks, i tried every setting app, i tried everything and the touchpad still doesnt work. You can click, you can't move, you can't scroll. The man didn't install anything, windows released an update and the single most important tool for interacting with the computer, one that is built into the hardware, was broken with no recourse to fix it, I'm simply not allowed access to the settings i require to maintain my own control over a functioning device.
That is the new settings app to me. Maybe if you stay within the ever shrinking bounds of control that Microsoft so graciously barely allows us to utilize, maybe then the buttons are rounder and the categories are better laid out. But if you need to fix anything that exists even slightly outside that toddler playground Microsoft is only ever making that more and more difficult under the guise of UI "improvements".
