Windows 10 Insider Preview Build 10576 available to Insiders on the Fast Ring

Today Microsoft released the Windows 10 Insider Preview Build 10576 to Windows Insiders on the fast ring. This version not only fixes some known bugs, but also includes some additional features as Media Casting from Microsoft Edge, using Cortana to search for related information regarding highlighted text in a PDF, and the latest Windows 10 Xbox Beta app .

The new feature that many will find useful is the ability to media cast directly from Microsoft Edge. Using media casting you can stream content playing within Microsoft Edge to a Miracast or DLNA enabled device on your network.  This means if your TV supports DLNA, which many do, you can use Edge to watch a YouTube video and stream it directly to the TV for big screen watching.  You can also use Edge to stream music such as Pandora or Sirius to DLNA enabled receivers.  Over all this is a nice feature that many will find useful.

 

 

The other main feature added, is the inclusion of the latest Xbox 10 Beta app that was released to the Microsoft Store on October 23rd. This version includes new features that allows you to link your account with Facebook and then recommends friends to play or share content with. This version also includes the ability to voiceover, or narrate, videos that you have created with the Game DVR. Last, but not least, this version also allows you to purchase games and redeem codes from the Xbox Store directly from your PC.

 

 

Items fixed in this build are:

• We fixed the issue where the Xbox app for Windows 10 would consume gigabytes of memory on your PC if you have any Win32 games (non -Windows Store games) installed on your PC that have been identified as games or added by you in the Xbox app.
• We introduced an early preview of nested virtualization so that people could run Hyper-V Containers in Hyper-V virtual machines with Build 10565. This build includes performance improvements.
• We’ve been addressing a lot of feedback around localization text UI in various languages and you’ll see a lot of that work in this build.
• The search box should now work in this build if you are in a locale where Cortana is not available.

Known issues:

• To continue receiving missed call notifications and send texts from Cortana, you will need to be on this build and higher. We’ve made a change that improves this experience that requires newer builds.
• When notifications pop up from Action Center, any audio playing (like music from Groove, or videos from the Movies & TV app) gets reduced by 75% for a period of time.
• After upgrading to this build, all your Skype messages and contacts are gone in the Messaging app. The workaround for this is to navigate to C:UsersAppDataLocalPackagesMicrosoft.Messaging_8wekyb3d8bbweLocalCache in File Explorer and either delete or rename the “PrivateTransportId” file. Then restart the Messaging app. Additionally, you can install the app from the Store as an updated app.
• Small form-factor devices, like the Dell Venue 8 Pro, that boot with rotation or virtual mode screen size set larger than the physical screen size will experience a bluescreen on upgrade and will roll back to the previous build.
• After upgrading to this build, the power button on your Surface Pro 3 may no longer put your Surface Pro 3 to sleep and instead shut down.
• WebM and VP9 have been temporarily removed from builds. We continue to develop a VP9 implementation that we intend to ship in Windows. Expect VP9 to return soon in a future build.
