Windows 11 Insider Dev Channel Preview Build 23516 adds screen casting improvements and more

Microsoft has released a new Windows 11 build for members of the Windows Insider program in the Dev channel. The new build version number is 23516. It includes a number of new features and improvements, including new additions for screen casting. support for HDR backgrounds, and more.

Keep in mind Microsoft is now doing a bug bash for new Windows 11 Insider builds where you can complete quests to help the development team fix some issues.

Here is the changelog:

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:

• When doing multitasking activities on your PC such as often switching between windows to complete a task or using Snap Assist to organize your screen space, we will provide the suggestion to Cast via a notification toast.
• We will now provide inline setup of a PC from within the Cast flyout in Quick Settings, with step-by-step guidance for users to enable:
  • Installation of the optional Wireless Display feature.
  • Discoverability of the PC to other devices, via the “Projecting to this PC” Settings page.

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.

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.

You can use voice access to login to your PC and access other areas on the Lock screen.

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.

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)

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.

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.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Devices and Drivers > Sensors.

Changes and Improvements

[Windows Copilot]

• [REMINDER] As of Build 23511, Windows Insiders in the Dev Channel who login and are managed by AAD (soon to be Microsoft Entra ID) will notice that the Windows Copilot Preview is no longer available in this build. This is just a temporary issue. You may enable it temporarily via this policy located here in Group Policy Editor: User Configuration > Administrative Templates > Windows Components > Windows Copilot. Please note that this policy name will change in an upcoming flight. The Windows Copilot Preview will be defaulted on in a future flight including support for Bing Chat for Enterprise.

[Taskbar & System Tray]

• As mentioned here with Build 23481, Microsoft Teams (free) is now pre-pinned to the taskbar in Windows 11. This change continues to roll out so not all Insiders will see it right away. Windows Insiders who click to launch Teams will discover a mini communications experience making it possible to chat, call, and meet with their people within just a click or two. Not only does its compact size make it easy to place the window anywhere on desktop, but you can passively keep tabs on their conversations with the ability to have it visible as they browse the web or connect with your communities. Phone Link integration is also coming soon.

As noted in our Beta Channel flight here, the settings for never combined mode for the taskbar were showing up under Settings > Personalization > Taskbar > Taskbar behaviors but do not enable the experience. We have temporarily removed the settings to fix the issue. The feature will be coming to a Beta Channel flight soon.

[File Explorer]

• Added 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.

Fixes

[General]
