Windows 10 Creators Update build 15019 is now available for fast ring members. The latest insider build brings many new features as well as improvements. However, the new build also comes with some known issues.

If you are facing issues like error 0xC1900401, build not yet available, download stuck at 0%, high CPU usage issue or other problems with the latest build, check out workaround here.

Known issues in Windows 10 build 15019

  • After updating to this build, nonstop exceptions in the Spectrum.exe service may occur causing PCs to lose audio, disk I/O usage to become very high, and apps like Microsoft Edge to become unresponsive when doing certain actions such as opening Settings. Tod fix this issue, delete – C:\ProgramData\Microsoft\Spectrum\PersistedSpatialAnchors and reboot.
  • Some Windows Insiders may have had trouble connecting to certain Google sites due to an implementation of a new security model being rolled out to further enhance user security. Users can access these sites from an InPrivate tab.
  • Extensions in Microsoft Edge do not work in this build. Extensions may appear to load but will not function as expected. This issue should be fixed in the next Insider release build we release.
  • Microsoft Edge F12 tools may intermittently crash, hang, and fail to accept inputs.
  • Microsoft Edge’s “Inspect Element” and “View Source” options don’t correctly launch to the DOM Explorer and Debugger, respectively.
  • Windows Insiders will unexpectedly see a “Mixed Reality” entry on the main page of Settings.
  • Some captive portal Wi-Fi networks may fail to connect during OOBE. If a captive portal network is using DNS hijacking to redirect to a secure site, the captive portal app will crash and the user cannot clear the portal.
  • Yes/No voice commands in the Wi-Fi portion of OOBE are currently failing.
  • Quicken 2016 will fail to run with an error stating .NET 4.6.1 is not installed. For Insiders familiar with Registry Editor, there is an optional workaround. Take ownership of the following registry keys and edit the “version” value to be 4.6.XXXXX instead of 4.7.XXXXX:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\NET Framework Setup\NDP\v4\Client
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\NET Framework Setup\NDP\v4\Full

Note: Please take caution when editing the registry.

  • Dragging apps from the all apps list to pin on Start’s tile grid won’t work. For now, please right-click on the desired app in order to pin it.
  • Some Tencent apps and games may crash or work correctly on this build.
  • Under Settings > Update & security > Windows Update you might see the text “Some Settings are managed by your organization” even though your PC isn’t being managed by an organization. This is a bug caused by an updated flight configuration setting for Insider Preview builds and does not mean your PC is being managed by anyone.
  • On some PCs, audio stops working sporadically with ‘device in use’ error”. Fix this issue by restarting the audio service may fix things for a bit.
  • The Action Center may sometimes appear blank and transparent without color. If you encounter this, try moving the taskbar to a different location on screen.

Gaming known issues

  • Popular games such as may experience crashes or black screens when trying to load due to a platform issue.
  • When clicking on certain elements in desktop (Win32) games, the game minimizes and cannot be restored.
  • Game Mode is enabled system-wide by default, however, the ON/OFF toggle in Settings will incorrectly show it as being OFF until the user manually toggles the Setting to ON which will cause it to update and accurately display the status of Game Mode system wide.
  • Broadcasting to Beam via the Game bar currently requires a number of Privacy settings to be changed.
  • Certain hardware configurations may cause the broadcast live review window in the Game bar to flash Green while you are Broadcasting. This does not affect the quality of your broadcast and is only visible to the Broadcaster.
