Did you try moving the taskbar, switching the default browser, or any other feature that they just decided to make harder, slower, or impossible?
People understandably get pissed off when features they have been using for over a decade suddenly disappear in an "upgrade". They expect things that used to work to keep working, and perhaps other things that didn't work to now work, but that's not what they got.
For me, the "new version of Windows is actually better" feeling faded around the 2K/XP timeframe. Since then it has only been increasingly minor improvements combined with increasingly greater regressions.
That's not entirely true. Microsoft did fix a lot of the device driver instability that plagued Win2k / XP around when they released Windows 7. Windows 10 was a further improvement in stability but at the expense of all the adware / telemetry. I've been running Windows 11 for a while and I don't hate it, but I spend more dev time in VSCode and WSL2 so it just feels like a weird Linux distribution that gets in the way.
