Windows 11 has reintroduced the option to use smaller Taskbar icons, which was absent at the operating system's launch. The feature allows users to enable smaller icons without reducing the height of the Taskbar. To activate smaller icons, users need to open Settings, click on Personalization, navigate to the Taskbar page, and adjust the Taskbar behaviors setting. Options include "Always" for consistently smaller icons, "When taskbar is full" for smaller icons when space allows, or "Never" to keep standard-size icons.
