One of the big new additions in Insider Preview Build 10576 is Media Casting in the Edge Internet browser. Microsoft has enabled the ability to cast audio, video, and picture content straight from your browser to Miracast- and DLNA-enabled devices on your home network. Microsoft notes that streaming audio services like Pandora and video sites like YouTube are supported, however, protected content from streaming video sites like Hulu and Netflix is blocked.
Screen casting was actually enabled in the Insider Preview Build 10576, but perhaps Microsoft wasn’t quite ready to announce the feature or was working on some final kinks before giving it the go-ahead for testers.

Ask Cortana support has been added to PDFs that are viewed within the Edge browser, allowing you to easily highlight content and call up additional information with the sound of your voice. You’ll also find an updated Xbox app in Windows 10. Speaking of the Xbox app, the memory leak that we mentioned in the last Insider Preview build has been plugged.
Microsoft has also improved performance of the nested virtualization functionality that we first talked about earlier this month. Nested virtualization allows you to run a host Windows 10 machine with a virtualized copy of Windows 10 running within yet another virtualized copy of Windows 10.
Windows 10 Insider Preview Build 10576 is currently available to all preview testers on the Fast ring. And as always, be sure to send your valuable feedback to Microsoft so that it can continue to improve its “Windows as a Service” model.
