Microsoft is urging enterprise customers not to install the most recent Windows 10 update because it may cause the Microsoft Defender Advanced Threat Protection (ATP) service to stop working. Microsoft Defender ATP is a paid service for enterprise customers not related to Windows Defender for the Home and Pro operating systems.
Microsoft warns that if companies install the October 15 KB4520062 cumulative update for Windows 10, “the Microsoft Defender Advanced Threat Protection (ATP) service might stop running and might fail to send reporting data.” In addition, users “might also receive a 0xc0000409 error in Event Viewer in MsSense.exe.” Users who have already installed the non-critical update, are recommended to uninstall it. Microsoft said it is working to resolve the issue, but warned that it might take until mid November before a fix becomes available.
