From memory: Ads. Weather and stock market info. Removal of options and features from windows 10 (why can't I have the taskbar vertically on the side of my wide monitor?). Flaky, slow and inconsistent bluetooth and sound controls. More and more things moving from control panel to settings where they are being dumbed down, leading to a lot more googling to figure out how to change things. Windows desperately trying to save things in onedrive rather than on the local disk. Really really trying to open everything in edge instead of the default browser.
