In the Windows 11 2023 Update, Microsoft is rolling out several visual changes and enhancements for the Taskbar and Start menu, making these experiences more valuable and customizable.

The Taskbar is the one receiving the most improvements. For example, in this release, you will once again be able to ungroup and show labels. A new entry has been added to terminate apps without resourcing to the Task Manager, and the Chat feature has been replaced for the Microsoft Teams free app, and you can now hide the clock from the System Tray.

As part of the Start menu changes, the second feature update for Windows 11 brings hover previews for cloud files, categorizes the system from non-system components, and adds new settings to control account notifications and more.
