Issues fixed in build 10576

• The giant company also 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.

Known issues in Windows 10 insider build 10576

• 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.
• 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.
