Microsoft has recently released Windows 11 Build 25346 for testers in the Windows Insider Program Canary Channel. The preview update includes several improvements and fixes, such as the support for Content Adaptive Brightness Control (CABC) on laptops and 2-in-1 devices, which was previously only available for desktop PCs.

CABC is a new feature introduced in Windows 11 that optimizes screen brightness and contrast levels based on the content displayed on the built-in screen, allowing for an ideal viewing experience while conserving power and extending battery life. The new update enables the feature for plugged-in laptops and 2-in-1 devices, which could result in longer battery life and reduced energy consumption.

Microsoft officials confirmed that the feature can be managed by going to Windows Settings > System > Display under “Brightness & colour.” Users can choose from three options: Off, Always, and “On Battery Only,” with the last one being the default setting for battery-powered devices. The tech giant is still working on the feature and wants testers to use the “Always” option instead and provide feedback on CABC’s visual quality to ensure proper tuning.

Aside from the CABC feature, Windows 11 Build 25346 also includes design improvements for legacy popups, such as the popup for incompatible apps/drivers or Windows Security alerts. The update introduces an updated look for Windows Security (firewall) notification dialogs, matching the Windows 11 visuals. Microsoft has also introduced several new features and enhancements to improve the user experience, including a redesigned connection bar for remote desktop sessions, an improved file-sharing experience in File Explorer, and a new option to hide the date and time on the taskbar.

To try these features, users can join the Windows Insider Program’s Canary Channel on a secondary device or virtual machine. It is worth noting that while the CABC feature aims to provide an ideal viewing experience in most cases while conserving power and extending battery life, some users may not like how it works. For tasks such as photo or video editing that require color accuracy, it is best to turn off CABC, although this might reduce battery life.

Windows 11 Build 25346 includes several improvements that enhance the user experience, such as a refreshed design for notification dialogs, improved file sharing, and a redesigned connection bar for remote desktop sessions. These enhancements demonstrate Microsoft’s commitment to providing a more streamlined and visually appealing operating system.

In addition to these updates, the support for CABC on laptops and 2-in-1 devices is a significant development. This feature optimizes screen brightness and contrast levels based on the content displayed on the screen, potentially resulting in longer battery life and reduced energy consumption. Users can manage this feature by going to Windows Settings > System > Display and choosing one of the three options available in the dropdown menu.

It’s worth noting that while CABC aims to provide an ideal viewing experience in most cases, some users may prefer to turn it off for tasks like photo or video editing, as it may affect color accuracy. Overall, Windows 11 Build 25346 includes several noteworthy updates that can improve the user experience, and testers can join the Windows Insider Program’s Canary Channel to try these features.
