Windows 11 creates local user directories using the first five letters of a user's email address instead of their actual name, which can be frustrating for users. The Taskbar thumbnail preview animations are lacking fluidity compared to previous Windows versions. Dark mode is inconsistent, with light mode interfaces appearing in various parts of the OS. Task View and Virtual Desktops animations can be choppy on systems without dedicated graphics cards. The transition between the Start menu and the Search pane feels abrupt and unrefined. Additionally, ads within Windows 11 lack personalization, leading to frustration for users who already subscribe to Microsoft services.
