Known issues

Again, 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 incorrectly 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.

Gaming known issues

  • Popular games 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.

Windows 10 Build 15019 Insider Preview hungs with ‘Initializing updates’

It seems that this build comes with a huge problem. I tried this night to let a machine install this build. But this morning the machine still hangs with the “Initializing updates” message.

Initialising updates

I tried to do a clean boot (press Shift key and select reboot), but till now no success. Searching the web, gave me this MS Answers forum post, where people succeeded after up to 9 reboots. This MS Answers forum thread brought the suggestion to do a Defender scan. What I’ve seen: Windows creates a couple of files within SoftwareDistribution/Download. Still experimenting, what will solve this issue – it’s a kind of Voodoo.

Microsoft’s employee Jason posted this MS Answers entry dealing with two errors (Error 0xC1900401 or “build not yet available” – that was fixed from Microsoft) and the “”Initializing updates” hung error. Jason suggests to end Windows Update service and restart it again. But that won’t work (I tried that in previous builds and also within the current build 15014) – Windows reports a timeout termination Windows Update service. Within the thread linked above, some users are proposing to switch off Update delivery optimization – but that wouldn’t helped in my case, because this requires terminating WU (which won’t work on my test machine).

My suggestion: Just reset WinRM

Rebooting a machine several times in the hope that Windows Update will be able to download build 15019 isn’t a kind of “Voodoo”, it’s also time consuming. I propose a more simple solution (see also) and reset the WinRM service.

1. Open a PowerShell command window as administrator (type PowerShell in taskbar’s search box, right click the search result PowerShell and use context menu command Run as administrator).

2. After confirming UAC prompt, enter the PowerShell command Restart-service WinRM and press the enter key.

This will restart the WinRM service. I tried it and was greeted by error 0x80070020, that means ERROR_SHARING_VIOLATION. Then I repeated the update search and was facing the “Initializing updates” message again.

More attempts

I tried to restart update search again and received error code 0x80246007 after a while. This code stands for WU_E_DM_NOTDOWNLOADEDThe update has not been downloaded.

After restarting update search again, I was greeted by a 100 % progress bar indicator (see above). At a first glance I thought the new update will be installed. But it just indicated, that preparing the download was successful.

But finally, a new update search has been started automatically and the progress bar (see screenshot above) begun to show some download progress. And I recognized this time, that something happens – my network bandwidth dropped, so I’m no more able to access the internet from other devices within my network.

The status so far …

It’s now 10 hours after my first attempt to install build 15019. Ok, I partially went to sleep, visited a baker shop in the morning, have had a long breakfast – and visited the test machine from time to time. Now the progress bar is at 99% – hope I will be successful to install that nasty beast on my test machine. But installing an Insider Preview seems to become a time/life consuming issue. Guess, Microsoft has a lot to improve, until Windows 10 Version 1704 is ready to be released to the public. I have to wait and see, if downloading and installing this build will make it finally – the weekend is still long …

… but: As a blogger, it’s always good to face such issues – so I still have a lot of topics to write and rant about Zwinkerndes Smiley.
