Also, there are a few known issues to be aware of:

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.
The Remote Access Connection Manager (RASMAN) service may stop working and you may receive the error “0xc0000005” on devices where the diagnostic data level is manually configured to the non-default setting of 0. You may also receive an error in the Application section of Windows Logs in Event Viewer with Event ID 1000 referencing “svchost.exe_RasMan” and “rasman.dll”. This issue only occurs when a VPN profile is configured as an Always On VPN (AOVPN) connection with or without device tunnel. This does not affect manual only VPN profiles or connections.	To mitigate this issue, use one of the steps below, either the group policy step or the registry step, to configure one of the default telemetry settings. Set the value for the following group policy settings: Group Policy Path: Computer Configuration\Administrative Templates\Windows Components\Data Collection and Preview Builds\Allow Telemetry Safe Policy Setting: Enabled and set to 1 (Basic) or 2 (Enhanced) or 3 (Full) Or set the following registry value: SubKey: HKEY_LOCAL_MACHINE\SOFTWARE\ Policies\Microsoft\Windows\DataCollection Setting: AllowTelemetry Type: REG_DWORD Value: 1, 2 or 3 Note If the Remote Access Connection Manager service is not running after setting the Group Policy or registry key, you will need to manually start the service or restart the device. We are working on a resolution and estimate a solution will be available in late July.
After installing this update, opening or using the Window-Eyes screen reader app may result in an error and some features may not function as expected. Note Users who have already migrated from Window-Eyes to Freedom Scientific's other screen reader, JAWS, should not be affected by this issue.	We are working on a resolution and will provide an update in an upcoming release.
