Microsoft today released Windows 11 Build 25346 preview to Canary Channel, this update includes some noteworthy improvements and fixes, the most important of which is support for the Content Adaptive Brightness Control (CABC) feature. This update includes some notable improvements and fixes, the most important of which is support for Content Adaptive Brightness Control (CABC), which helps laptops and 2-in-1 devices save power.
The CABC feature automatically adjusts brightness and contrast based on the content displayed on the screen, for example, when switching from a dark scene to a bright sunny scene in a video, the brightness and contrast will change accordingly. This feature was previously only available for desktops, but now it is also available on laptops and 2-in-1 devices.
Users can manage this feature in “Brightness and Color” under Windows Settings > System > Display, with three options: off, always on, and only on when using the battery. Microsoft expects testers to use the “always on” option and to provide feedback on the visual quality of CABC so that appropriate adjustments can be made. This feature is intended to provide an ideal viewing experience in most cases while saving power and extending battery life. However, for some tasks that require color accuracy, such as photo or video editing, it is best to turn off the CABC feature.
In addition to the CABC feature, Windows 11 Build 25346 also brings some design improvements. For example, Microsoft has updated the appearance of the Windows Security (Firewall) notification dialog box to match the visual style of Windows 11. In addition, several new features have been added to improve the user experience: the connection bar for remote desktop sessions has been redesigned with a fresher light and dark mode design; the file sharing experience in File Explorer has been improved; and there is a new option to hide the date and time on the taskbar to make the taskbar look cleaner.
