What’s new in Build 23516

Improving the screen casting experience

Casting from your Windows PC allows you to wirelessly extend your display to another nearby PC, TV or other external displays. We are making some improvements that focus on educating people about the Cast feature, improving its discoverability, and simplifying the overall experience in Windows 11. Those improvements include:

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Display and Graphics > Wireless Display and Casting.

HDR Background Support 

You can now set JXR files to be your desktop background and if you have an HDR display, they will render in full HDR.

First – make sure your device has an HDR display or is connected to a HDR display that supports HDR. You can check this by going to Settings > System > Display and checking the HDR toggle.

Next, download an HDR .JXR file to your device. Then right-click on your desktop, choose “Personalize” and then “Background”, and under “Personalize your background” – go and select the .JXR file you downloaded to your device.

[ADDED] You can download example .JXR files here to try this experience out on your HDR-capable device/display.

The background should load on your display. If you have multiple displays attached to your device, the background will show as HDR or SDR depending on each display’s capabilities. When using external displays attached to your device, we recommend running the HDR Calibration app for best picture quality. Please note that for this build, there may be some issues with the HDR version of the desktop background not correctly display on some laptops with HDR.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Background and Wallpaper.

Voice access is now available to use on more areas in Windows

We have added support for voice access to work right when you start your PC. You can use voice access to login to your PC and access other areas on the Lock screen. You can turn on voice access from the accessibility flyout on Lock screen or have it on automatically every time by checking the setting to “Start voice access before you sign in to your PC”  via Settings > Accessibility > Speech.

Note: If you have never tried voice access, we recommend you search for voice access in search on the taskbar and complete the initial setup before trying it first time on the lock screen.

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. Alternatively, you can 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. This will mask the actual password you are entering from being heard by anyone in your vicinity.

You can also use other commands such as “show numbers” or “click [element name]” to access other elements on lock screen or UAC prompt.

And voice access now works for apps running with Microsoft Defender Application Guard.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Accessibility > Voice Access.

Narrator Natural Voices in French, Portuguese, English (India) ,German and Korea

We are introducing new natural voices in French, Portuguese, English (India) ,German and Korean that allow Narrator users to comfortably browse the web, read, and write mail, and do more. Natural Narrator voices use modern, on-device text to speech and once downloaded are supported without an internet connection.

To use one of the natural voices, add it to your PC by following these steps:

  1. Open Narrator Settings by pressing the WIN + Ctrl + N hotkey.
  2. Under Narrator’s voice, select the Add button next to Add natural voices.
  3. Select the voice you want to install. You can install all voices, but you must install them separately.
    • The new French voices are Microsoft Denise (Female) and Microsoft Henri (Male)
    • The new 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)
    • The new Korean voices are Microsoft SunHi (Female) and Microsoft InJoon (Male)
  4. To start the download of the selected voice, select Install. The new voice will download and be ready for use in a few minutes, depending on your internet download speed.
  5. When the new voice has downloaded, in Narrator settings select your preferred voice from the drop-down menu in Narrator’s voice > Choose a voice.

Note: If your display language is not set to any of the above languages, then in step 3 you will first need to select “Choose a different language” and then select the appropriate language followed by the specific voice.

FEEDBACK: Please file feedback in Feedback Hub (Win + F) under Accessibility > Narrator.

Presence Sensing Improvements

For PCs with presence sensors that support attention detection, we are introducing Adaptive Dimming. Now your device can intelligently dim your screen when you look away and undim when you look back. You will find these settings under Settings > Privacy & security > Presence sensing here if your device supports it.

Wake on Approach, Lock on Leave, Adaptive Dimming are all powered by Presence Sensing in Windows and now can be enabled via the OOBE (“out of box experience”) setup process when choosing your privacy settings for your device. This will give more control of the presence sensing features and app access to presence information when setting up a new device with a compatible sensor.

As a reminder, app developers with devices with compatible presence sensors can target apps to request and read user presence information after requesting a human presence capability. Learn more about the API here.

For developers

You can download the latest Windows Insider SDK at aka.ms/windowsinsidersdk.

SDK NuGet packages are now also flighting at NuGet Gallery | WindowsSDK which include:

These NuGet packages provide more granular access to the SDK and better integration in CI/CD pipelines.

SDK flights are now published for both the Canary and Dev Channels, so be sure to choose the right version for your Insider Channel.

Remember to use adaptive code when targeting new APIs to make sure your app runs on all customer machines, particularly when building against the Dev Channel SDK. Feature detection is recommended over OS version checks, as OS version checks are unreliable and will not work as expected in all cases.

About the Dev Channel

REMINDER: The Dev Channel has been rebooted. Windows Insiders who were in the Dev Channel on 25000 series builds have been moved to the new Canary Channel. Going forward, the Dev Channel will receive 23000 series builds. Insiders who were moved to the Canary Channel and want to move back to the Dev Channel can follow these instructions to do a clean installation of Windows 11 and then re-join the Dev Channel to receive 23000 series builds.

The Dev Channel receives builds that represent long lead work from our engineers with features and experiences that may never get released as we try out different concepts and get feedback. It is important to remember that the builds we release to the Dev Channel should not be seen as matched to any specific release of Windows and the features included may change over time, be removed, or replaced in Insider builds or may never be released beyond Windows Insiders to general customers. For more information, please read this blog post about how we plan to use the Dev Channel to incubate new ideas, work on long lead items, and control the states of individual features.

In some cases, features and experiences may go out to the Canary Channel first before going out to the Dev Channel however the Dev Channel will provide better platform stability. As we get closer to shipping, some features and experiences will also make their way to the Beta Channel when they are ready.

The desktop watermark you see at the lower right corner of your desktop is normal for these pre-release builds.
