Microsoft Has Released Windows 10 Build 10576 To Insiders

Windows 10

Microsoft has released a new build of Windows 10 to Insiders today that brings Fast ring users up to version 10576. This is the second build that Microsoft has released today, they pushed out a new version of Windows 10 Mobile that you can read about here.

In this release, Microsoft has added the ability to cast media from Edge which means that you can now use the browser to send video, picture and audio content from your browser to any Miracast or DLNA device.

With Cortana you can now highlight a word in a PDF and right-click to “Ask Cortana” to find more information about the topic.

What has been fixed in this build:

  • Microsoft 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.
  • Microsoft 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.
  • Microsoft addressed 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 with this build:

  • To continue receiving missed call notifications and send texts from Cortana, you will need to be on this build and higher. Microsoft 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:\Users\<USERNAME>\AppData\Local\Packages\Microsoft.Messaging_8wekyb3d8bbwe\LocalCache 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.

This build is another pre-release of the upcoming fall update (also known as Threshold wave 2) to Windows 10 that Microsoft will eventually push to all Windows 10 users. While the company has not announced the date of its release, it is expected to arrive in early November.
