Media Casting in Microsoft Edge: You can now use Microsoft Edge to cast video, pictures, and audio content from your browser to any Miracast and DLNA enabled device on your network.

We've got a few scenarios for you to try out:

  • Cast a video from YouTube: Go to in Microsoft Edge. Click on the "…" menu on the top right, and select "Cast media to device" and select the Miracast or DLNA device you want to cast to.
  • Cast a Facebook photo album: Login to Facebook in Microsoft Edge and click on the first photo in one of your photo albums to cast. Click on the "…" menu on the top right, and select "Cast media to device" and select the Miracast or DLNA device you want to cast to. Navigate through your photo album by clicking on the forward and backward buttons.
  • Cast your music from Pandora: Login to Pandora in Microsoft Edge to get to your music and click on the "…" menu on the top right, and select "Cast media to device" and select the Miracast or DLNA device you want to cast to.

Please note: Casting protected content (content from places like Netflix and Hulu) is not supported.

Ask Cortana inside PDFs in Microsoft Edge: You can now highlight text while reading a PDF in Microsoft Edge and right-click to "Ask Cortana" to find additional information.

Updated Xbox beta app for Windows 10: The Xbox beta app for Windows 10 was updated last Friday which includes the ability to easily find and add Facebook friends who are also on Xbox Live to play, chat, and share clips – a top requested feature. In addition to that new feature, voiceover recording functionality has been added to Game DVR, and the Store in the Xbox beta app will allow you to search for and purchase Xbox One games – including Games with Gold and Deals with Gold promotions, and Xbox One 25-digit codes will be redeemable within the app. For more information on this update – check out this post on Xbox Wire.

Windows has supported Miracast since Windows 8.1 and the Connect flyout in Windows 10 (Win + K) already supports wireless casting.

'Cast media to device' functionality was there in earlier Insider builds of Windows 10 but now seems to be ready to be advertised officially. Tip: Shortcuts with Windows (Win) key every Windows 10 user should know.

That's it. It is quite possible that the build contains a number of secret hidden changes under the hood. We will keep you informed as long as we are able to discover new features in Windows 10 build 10576. Stay tuned.
