Microsoft has instructed their enterprise-based customers, who have installed the KB4520062 cumulative update for Windows 10, to uninstall it.  This comes after the update, issued on the 15th October, turned out to break the Windows Defender Advanced Threat Protection  (ATP) service; which is essential to detect, investigate and respond to “advanced threats.”

In Microsoft’s release notes, the warning reads as follows:

After installing this update, the Microsoft Defender Advanced Threat Protection (ATP) service might stop running and might fail to send reporting data,” the warning reads. “You might also receive a 0xc0000409 error in Event Viewer in MsSense.exe

Microsoft has confirmed they are “working on a resolution”, which may take as long as mid-November to complete. Until then, businesses and corporations need to make sure to uninstall the update in the interest of security.
