Microsoft has released a new Windows 11 preview build that will allow users to test the company’s adaptive brightness feature on more devices. The Content Adaptive Brightness Control (CABC) feature, which previously only worked on laptops running on battery, can now be toggled on plugged-in devices, including desktop PCs.
The feature uses visual content to adjust the brightness of a display or monitor in order to balance power consumption with the visual experience, and is expected to help reduce energy consumption for most users.
While enabling CABC will likely be unnoticeable for most users, Microsoft has warned that the sudden changes in brightness and contrast may be distracting for users who require color accuracy.
As such, Windows Insiders are being asked to provide feedback on the visual quality of the feature, with the aim of adjusting CABC before its stable release.
Insiders can configure the CABC feature using a drop-down menu under “Brightness & color” by going to Settings > System > Display, and choosing from the available options: Off, Always, and On Battery Only.
In addition to the CABC feature, Microsoft is also testing a Windows Update option called “Get the latest updates as soon as they are available” with Insiders in the Dev Channel.
The option will fast-track non-security updates to systems where it’s toggled on, and is designed to help Microsoft ensure that the new toggle is connected to its backend services correctly before making it available in the Beta Channel.
The company is also rolling out the Windows 11 Insider Preview Build 25330 to Insiders in the Canary channel, which comes with several Microsoft Store improvements, including the option to install free apps and games directly from search results, a redesigned purchasing experience, and new UX for in-app ratings.
