Microsoft has followed up the Windows 10 Build 14931 with the Build 14936 for Fast Ring. Build 14396 is now available to download and install for Insiders in Fast Ring. The Build mostly brings fixes and improvements along with some Windows Subsystem for Linux (WSL) Updates.

Read on for full Changelog and Known Issues below.

Windows 10 Build 14936 Changelog:

  • Authentication changes affecting connectivity to NAS devices and home file servers: After updating to the latest Insider Preview builds, you may have noticed that shared devices on your home network have disappeared from your home network folder. You may have also noticed your mapped network drives are not available. If you change your network to “private” or “enterprise”, it should start working again. For more information on this behavior change, see this Microsoft Security Bulletin.
  • Windows Subsystem for Linux (WSL) Updates: WSL will install Ubuntu version 16.04 (Xenial) instead of Ubuntu 14.04 (Trusty) in an upcoming release. This change will apply to Insiders installing new instances (lxrun.exe /install or first run of bash.exe). Existing instances with Trusty will not be upgraded automatically. Users can upgrade their Trusty image to Xenial using the do-release-upgrade command. Full WSL release notes can be found here.
  • We fixed the issue causing Narrator to continually speak the progress of a song e.g. update with the current time of the progress bar every second if you navigate to the progress bar while a song is playing in Groove Music.
  • We fixed the issue where using the tab key to navigate the Settings app wouldn’t work.
  • We fixed an issue resulting in Explorer.exe frequently crashing for some Insiders, particularly for those with multiple network switches.
