Announcing Windows 11 Insider Preview Build 23516

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 23516 to the Dev Channel. 

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.

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.

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.

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.
