Microsoft is releasing the Windows 11 build 25346 for computers enrolled in the Canary Channel of the Windows Insider Program. This is a minor update, but it includes more interface visual changes and new settings.

Build 25346 for Windows 11, according to the official changes, introduces changes for the Content Adaptive Brightness Control (CABC) feature. The Remote Desktop connection bar has been redesigned to align with the new style design of the operating system. In addition, the company is re-introducing a new dialog interface for Windows Security (firewall) notifications. 

Furthermore, the Settings app includes a new presence-sensing privacy feature that allows apps to determine if your presence nearby the device when compatible sensors are available, and it’s now easier to enable or disable HDR when running on battery.

These are all the new features and improvements for the latest release of Windows 11 in the Canary Channel:

You can change the settings of the feature on Settings > System > Display and then under “Brightness & color” and through a drop-down menu with three options, including “Off,” “Always,” and “On Battery Only.”

Remote Desktop new connection bar

The Remote Desktop experience is getting a new connection bar for remote desktop sessions to a new refreshed light and dark mode design that aligns with the Windows 11 design principles.

File Explorer

You will now see the option to quickly email the file to yourself when sharing a local file in File Explorer to Outlook contacts. In addition, Microsoft made improvements in loading your contacts from Outlook.

New Presence sensing settings

Starting on Windows 11 build 25346, the Settings app introduces new presence sensor privacy settings and APIs on Settings > Privacy & security > Presence sensing. However, the settings page is only available on devices with compatible presence sensors. If this is the case, you can now manage your privacy and block or allow certain apps from accessing these sensors. Microsoft will not collect images or metadata, and all processing is done locally on the device’s hardware to maximize privacy.

Windows Narrator

Finally, Windows Narrator users who interact with Traditional Chinese characters are now able to do this with confidence while using Narrator and the IME candidate window in Windows. 

Also, the Windows Narrator now consumes the dictionary to disambiguate each Traditional Chinese word.

Install build 25346

If you want to download and install the Windows 11 build 25346, enroll your device in the Canary Channel using the “Windows Insider Program” settings from the “Windows Update” section.

Once you enroll the computer in the program, you can download build 25346 from the “Windows Update” settings by clicking the “Check for Updates” button. However, you will need a device that meets the minimum system requirements to receive the update if you are new to the Windows Insider Program.
