Here are the fixes, improvements, and known issues in Windows 10 for PCs build 15019

It's late in the week, but Microsoft kept its promise to deliver a new Fast ring build. It contains the gaming features that were outlined earlier this week, but build 15019 also features much more.

Along with things like Game Mode and built-in Beam streaming, Insiders also get more improvements to the out-of-box experience (OOBE), Edge can read aloud, and the browser will also display colorful emojis by default.

As always though, it contains a very long list of fixes, improvements, and known issues. Here are the fixes and improvements for Windows 10 for PCs build 15019:

• We fixed an issue where connecting an Xbox 360 or Xbox One Controller to your PC would cause the DWM to crash, resulting in your display flickering and/or appearing blank or black.

• We fixed an issue from Build 15014 where using Hey Cortana might result in SpeechRuntime.exe using an unexpected amount of CPU.

• We fixed an issue where, with a maximized Notepad window and enough text to require a scrollbar, the right-most edge of the scrollbar wouldn’t do anything when dragged in an attempt to scroll.

• We fixed an issue where, after pressing Alt to set focus to the menu bar, certain apps could become unresponsive if then pressing Ctrl or clicking inside the app’s child window.

Here are the non-gaming-related known issues:

• IMPORTANT: The download progress indicator shown when downloading this build is currently broken under Settings > Update & security > Windows Update. It may look like you’re getting stuck at 0% or at other percentages. Ignore the indicator and be patient. The build should download fine and the installation should kick off. See this forum post for more details.

• 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. As a workaround to get out of this state, you can delete C:\ProgramData\Microsoft\Spectrum\PersistedSpatialAnchors and reboot. For more details, see this forum post.

• 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. The team is working on a resolution. In the meantime, 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. If you depend on extensions in Microsoft Edge, we recommend skipping this build. You can pause Insider Preview builds by going to Settings > Updates & security > Windows Insider Program, clicking on “Stop Insider Preview builds”, and choosing “Pause updates for a bit”.

• 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. Changing the wrong value can have unexpected and undesirable results.

• 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”. We are investigating. 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.

Here are the gaming-related 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. Please visit this forum post.

• 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.

There are also some platform-related issues that will affect Insiders' ability to play some popular games. The announcement makes it clear that these bugs are not related to the new Game Mode or other new gaming features.

In you're on the Fast ring, you can install 15019 by heading over to Settings -> Updates & security -> Windows Update -> Check for updates. If you're not, go to the Windows Insider Program and select "Get started". When your PC reboots, go back and make sure that you're in the Fast ring.
