Some valid, a lot overblown. Take everything with a grain of salt.
A lot of people on Lemmy revere Linux to the point that Windows anything is a dirty word, so negative qualities are amplified quite substantially in discussions here.
I use Windows 11 daily on my personal laptop. As (what I am assuming to be) a typical end user, I will say I don’t hate or love it any more than Windows 10. But I’ve never been one to nitpick over small details as much as others seem to.
I’m generally unfazed by start menu changes because I access the majority of my apps by just typing the name into the start menu. The dedicated search button in Windows 10 is superfluous for that reason, so I never used it and don’t miss it. Rounded corners vs straight corners in the UI is essentially meaningless. And while Windows 11 currently does not allow you to reposition the taskbar to other sides of the screen, Windows 10 doesn’t allow the taskbar and start menu to be centered, so pick your poison.
I think the right click context menu is improved in Windows 11 over 10.
