Microsoft has been working hard to update the system interface of Windows 11, and gradually redesigning the native apps to match the modern design style. Following the Windows Media Player, Notepad, and Photos apps, some users have also discovered a hidden task manager with a new UI in the latest Build 22538.

Microsoft has not changed the Task Manager UI since Windows 8 in 2012, which means this is the first major change in 10 years. As you can see from the image, the new version of Task Manager features Windows 11's Fluent Design, support for light/dark modes, and the previous top bar menu replaced with a sidebar.

However, this Task Manager is still in its early stages, many features are not available, and the UI is not fully adapted and needs further optimization, which may be the reason why Microsoft hide it for now.
