 * After updating to this build, constant crashes with the  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. To fix this, navigate to C:\ProgramData\Microsoft\Spectrum, and delete the PersistedSpatialAnchors folder.
 * Some systems may crash with a GSOD caused by  during the installation of this build, causing it to rollback to the previous build.
 * Sometimes the audio can randomly stop working with a "device in use" error. Restarting the "Windows Audio" service can temporarily fix the problem.
 * 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.
 * Quicken 2017 will fail to run with an error stating that the .NET Framework 4.6.1 is not installed.
