Known issues in this update

Symptom Workaround
Windows Sandbox may fail to start with “ERROR_FILE_NOT_FOUND (0x80070002)” on devices in which the operating system language is changed during the update process when installing Windows 10, version 1903. Microsoft is working on a resolution and will provide an update in an upcoming release.
Devices that start up using Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) or System Center Configuration Manager (SCCM) may fail to start with the error “Status: 0xc0000001, Info: A required device isn’t connected or can’t be accessed” after installing this update on a WDS server. We are working on a resolution and will provide an update in an upcoming release.
Devices connected to a domain that is configured to use MIT Kerberos realms may not start up or may continue to restart after installation of this update. Devices that are domain controllers or domain members are both affected.

If you are not sure if your device is affected, contact your administrator. Advanced users can check if this registry key exists HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System\Kerberos\MitRealms or for “Define interoperable Kerberos v5 realm settings” policy under Computer Configuration -> Policies -> Administrative Templates > System -> Kerberos.

At this time, we suggest that devices in an affected environment do not install this update. We are working on a resolution and estimate a solution will be available in late August.
After installing this update, applications that were made using Visual Basic 6 (VB6), macros using Visual Basic for Applications (VBA), and scripts or apps using Visual Basic Scripting Edition (VBScript) may stop responding and you may receive an “invalid procedure call error.” Microsoft is presently investigating this issue and will provide an update when available.
