KB4520062 for Windows 10 1809 may break Microsoft Advanced Threat Protection
Microsoft released the second back of October 2019 updates for various supported Windows 10 versions on October 15, 2019. The cumulative updates, all non-security, fix various issues in Windows 10.
It is usually a good idea to postpone the installation of the second wave of updates of any given month unless systems are affected by issues fixed in those.
One of the main reasons for that, apart from reducing the burden on administrators, is that updates may introduce new known issues that affect devices that are upgraded.
Microsoft's track record in the past year has not been the best in regards to update quality. While the company claimed that update quality is better than ever, user perception seems to suggest otherwise: from Windows 10 version 1809 which the company had to pull for six weeks after release because of stopper bugs to more recent updates that introduced a whole number of issues.
KB4520062, the most recent update for Windows 10 version 1809, released October 15, 2019, introduced a new bug that affects Microsoft Advanced Threat Protection.
Microsoft added the issue to the list of known issues on the support page of the update:
After installing this update, the Microsoft Defender Advanced Threat Protection (ATP) service might stop running and might fail to send reporting data. You might also receive a 0xc0000409 error in Event Viewer in MsSense.exe.
The company suggests that the update should not be installed on devices which rely on Microsoft Defender Advanced Threat Protection functionality.
At this time, we suggest that devices in an affected environment do not install this update.
Microsoft hopes that it will have a solution for the issue ready in mid-November, likely in time for the November 2019 Patch Day on November 12, 2019. Microsoft releases security updates for all supported versions of Windows on the second Tuesday of any month.
The known issues page on the Microsoft Docs website for Windows 10 version 1809 lists the issue as well as an unresolved issue. It lists Windows 10 version 1809, Windows 10 Enterprise LTSC 2019 and Windows Server version 1809 / Windows Server 2019 as affected operating systems.
Microsoft did not add the issue to other versions of Windows 10 that it released cumulative updates for on October 15, 2019.
Microsoft is the worst possible Windows virus…
I think i will install this ‘feature’ and block any other fix to it. :D
With zero testing comes zero reliability.
“The company suggests that the update is not installed on devices which rely on Microsoft Defender Advanced Threat Protection functionality.”
what does it mean
It should not be installed on devices on which the feature is active.
Enterprise subscriptions only?
Yes that is correct.
The best update policy is to defer updates for 60 days and feature updates for 180. m$ thinks they can fix broken updates with their propaganda campaign.
“Microsoft Defender Advanced Threat Protection (ATP)”
What does it do? Advanced snakeoil sounds good :-)
With such a high percentage of faulty updates, I have become frozen in fear of breaking another system(last time I updated it put the system into a never ending update boot loop and had to reinstall the OS).
Maybe it would be preferable to do an article on the few updates the dont break anything are therefore safe to install and how to install them without fear of including broken updates.
~just a thought
“Maybe we’ll fix it in a month when we throw a bucket of new updates at you.”
Not to worry, MS’s beta testers (everyone who keeps Defender and its offspring active because it’s now so good) will sort things out.
Can any part of Windows be consistently good when MS wrecks it wack a mole style every two weeks? Something’s always broken.
