Issues fixed in build 10576

  • Microsoft fixed the issue where the Xbox app for Windows 10 would consume GBs 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.
  • 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.
  • They are also 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 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.
