As expected earlier today Microsoft released Windows 10 Build 10576 to Windows Insiders on Fast Ring. The latest build comes with many improvements in Microsoft Edge and there some fixes included in this build.
However as it is a preview build, there are some known issues which you need to check before installing the build.
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 this folder in File Explorer:
- C:\Users\<USERNAME>\AppData\Local\Packages\
Microsoft.Messaging_8wekyb3d8bbwe\LocalCache - Delete or rename the “PrivateTransportId” file.
- Then restart the Messaging app.
- C:\Users\<USERNAME>\AppData\Local\Packages\
- 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.
