Windows 10 Update KB4520062 Could Break Defender ATP, Microsoft Warns



It's time for one more Microsoft Windows 10 'thing'. A few days ago a Windows 10 update KB4520062 patch was released, Microsoft began advising businesses and organizations on Thursday, Oct 17, not to install the update as it can break the Windows Defender Advanced Threat Protection (ATP) service.
“After installing the optional non-security update (KB4520062), 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 on MsSense.exe,” Microsoft explained in a post.
The update, which was rolled out by the tech giant on Oct 15 and the second cumulative update this month, offers several impressive highlights. These include updates concerning issues on power consumption, Bluetooth, Settings app, Windows Mixed Reality Portal, and many more reports myce:
Although the glitch won’t affect all 900 million users of Windows 10, the revelation comes as bad news to businesses and organizations that rely on Windows Defender ATP for antivirus and threat trackers.
Designed to work as an anti-malware component, the Windows Defender Advanced Threat Protection (ATP) serves to “help enterprise networks prevent, detect, investigate, and respond to advanced threats.”
It was built with endpoint behavioral sensors, cloud security analytics, and threat intelligence. By downloading the KB4520062 update, organizations are at risk of having their Windows ATP compromised, making their system become more vulnerable to cyberattacks.
Fortunately, the glitch is reported to affect only Windows 10 version 1809, Windows 10 Enterprise LTSC 2019, Windows Server version 1809, and Windows Server 2019. The KB4520062 also only works as a non-security and optional update, which means users can opt not to install it.
Those who have already installed the update, however, are at risk of experiencing the problem mentioned by the company and can only opt to uninstall the update to fix the issue.
The uninstallation can be done by simply going to the Control Panel of an affected device. From there, users will need to go to the “Programs” section, view the “Programs and Features” category, and click on the “View installed updates” located in the left sidebar.
From there, users will need to click on the KB4520062 entry and uninstall the update from their device.
“At this time, we suggest that devices in an affected environment do not install the optional non-security update, KB4520062. We are working on a resolution and estimate a solution will be available in mid-November,” the tech giant added.

Ain`t that obvious - different teams at MS went to the war path (with each other).

I don't know why they refuse to return to modular and optional updates in spite of all the broken updates.The previous model worked for over 20 years and the new one has been screw-up after screw-up.

Microsoft simply got tired of the majority of Windows users neglecting the updates and then being blamed for all Windows OSes being parts of botnets
I also want Windows 10 updates to work like back in Win7 and earlier, but I can see why Microsoft chose to change it
You also have the case of Microsoft wanting the latest DX12 features supported on all Windows 10 PCs.
They don't want to have a repeat of how it was for Vista and Win7, where Microsoft released a DX11 platform update for Vista to further drive DX11 adoption, but Vista users kept acting like a clog by not updating.

Microsoft Windows team is beyond salvation.
But hey, in the end this team has the task of will introducing the "broken WaaS " model.
Windows 10 will be forever remembered as the "broken"model. In almost every aspect regarding an operating system.
Is Linux better. Depending of your needs, you can ALWAYS choose.

Oh dear...MS doing more alpha testing on the public, because 'they can'. Unfortunately, and I can't see that changing anytime soon. Another down side to a monopoly.

Yes...here we go again! A few days ago I decided to "un-pause" updates on my Windows 10 computer, and 2 updates were promptly offered. Of those 2, only one would install. KB4517389 would not install, I even went to Microsoft's download catalogue website and tried to manually install it, but no, it still refused to install. In my opinion, Windows 10 updates are definitely poorly engineered and coded!

Notice that no user reports this time. MS caught the bug. Big improvement.
