Windows 11 build 23516 new features

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


Starting with build 23516, Windows 11 introduces various changes for Cart, which is the feature that allows you to wirelessly extend your display to another nearby computer, TV, or other external displays.

Cast new UI

The company says that it’s improving discoverability and making it easier to use by adding a suggestion to use Cast with a toast notification when it detects that you’re doing multitasking activities, such as often switching between windows to complete a task or using Snap Assist.

In addition, the feature will provide inline guidance within the Cast flyout in Quick Settings to install the Wireless Display optional feature and offer better discoverability of the computer to other devices through the “Projecting to this PC” settings page.

HDR wallpapers

Windows 11 now has the ability to use JXR files as desktop backgrounds, and if you have an HDR display, they will render in full HDR.

If you have multiple displays attached to your device, the background will show as HDR or SDR, depending on each display’s capabilities. This makes it possible for your device to intelligently dim your screen when you look away and brighten it again when you look back.

Presence Sensing

On devices with presence sensors that support attention detection, Windows 11 build 23516 introduces Adaptive Dimming.

Furthermore, Wake-on Approach, Lock-on Leave, and Adaptive Dimming are part of Presence Sensing and can now be enabled through the out-of-box experience setup process when choosing your privacy settings for your device.

File Explorer

As part of the File Explorer changes, this flight adds more fields to show in the Details pane, including image dimensions for pictures, number of pages for .docx, space used and free information for drives, and many others.

Voice Access 

On build 23516, it’s now possible to use Voice Access from the Lock screen using the Accessibility menu from the bottom-right corner.

In addition, you can follow the instructions on the voice access bar to get your focus on the password field and use your voice to dictate your password or PIN. Furthermore, it’s possible to say “show keyboard” to bring up the touch keyboard with number labels on it. You can say the numbers on the keys to enter the letters associated with it.

Finally, you can also use other commands, such as “show numbers” or “click [element name]” to access other elements on the Lock screen or UAC prompt.

Windows Narrator Voices

Microsoft is also introducing new natural voices in French, Portuguese, English (India), German, and Korean that allow Windows Narrator users to comfortably browse the web, read and write mail, and more.

The new French voices are Microsoft Denise (Female) and Microsoft Henri (Male), and the Portuguese voices are Microsoft Francisca (Female) and Microsoft Antonio (Male). The new English (India) voices are Microsoft Neerja (Female) and Microsoft Prabhat (Male). The new German voices are Microsoft Katja (Female) and Microsoft Conrad (Male), and the new Korean voices are Microsoft SunHi (Female) and Microsoft InJoon (Male).
