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.

• 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.

• 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.

• 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 the 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.
