Known Issues with KB4507453

1- Symptom

While starting the computer, the Windows Sandbox may fail to launch with “ERROR_FILE_NOT_FOUND (0x80070002)”. Here the language of the OS may alter during the update process when installing Windows 10, version 19H1.


Wait for some time as the company is working on a solution to this issue.

2- Symptom

In this update, The Remote Access Connection Manager service may discontinue running and by which you may undergo the error “0xc0000005” on your devices. Here the diagnostic data level is manually configured to the non-default setting of zero (0). Besides, you may also encounter an error in the Application section of Windows Logs in Event Viewer. This error has the Event ID 1000 referencing “svchost.exe_RasMan” and “rasman.dll”.

Additionally, this issue appears particularly 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.


You can reduce this problem by using one of the steps below. Moreover, 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-

  1. Group Policy Path- Computer Configuration\Administrative Templates\Windows Components\Data Collection and Preview Builds\Allow Telemetry
  2. 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


Value: 1, 2 or 3

Note- If the Remote Access Connection Manager service is not working 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.
