“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.”
Before going on a red alert, this issue pertains to Microsoft’s enterprise-based customers. Microsoft Defender Advanced Threat Protection is a paid service for detecting, investigating, and responding to “advanced threats.” It’s built into Windows 10 but unrelated to the Windows Security platform found in Windows 10 Home and Pro.
Microsoft notes that it’s currently “working on a resolution” but doesn’t expect an official fix until the middle of November. That means businesses and corporations should not install this update until then. If the update is already installed, issues with the Microsoft Defender Advanced Threat Protection platform may already be in effect. Uninstall the update and wait for a fix.
While the issue doesn’t target mainstream customers, it’s notable because the update follows a series of problems with updating Windows 10 over the last month. Microsoft released an update on September 16 that broke Windows Defender. The update that was distributed on October 3 caused problems with the Start Menu and broke the print spooler. Five days later, many users complained about the still-broken Start Menu with the October 8 update.
Microsoft released a servicing stack update on October 8. The company warns that all customers should install this update before any other update(s). The company explains that the servicing stack is “the component that installs Windows updates.” The latest patch improves the reliability of the update process, meaning Windows 10 devices can’t properly update unless they keep the service stack current.
Despite the issue with Microsoft Defender Advanced Threat Protection, the KB4520062 cumulative update brings a large list of fixes and improvements. It addresses an issue that causes high CPU usage when Background Application Manager runs a scan while multiple windows remain open. It fixes a Bluetooth issue tied to audio profiles and a problem that involves naming Microsoft SharePoint files incorrectly.
Here are a few other interesting fixes:
Did you think hitting delete on your AI chatbot conversation actually makes it disappear? Georgia Tech researchers just proved that's not entirely true. They have built a forensic tool called ORISA that can dig deleted conversations from your phone and even rebuild them into a working chatbot session you can keep talking to.
How can ORISA bring deleted AI conversations back?
Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind.
The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).
Two residents of Chicago have filed a lawsuit in the US over claims that robots run by Coco Robotics and Serve Robotics captured their facial and hand measurements without consent, bringing renewed attention to the food delivery robots. The cases raise a troubling question: If a robot delivers food to your door, can it also be gathering sensitive information about you?
According to a report by The Associated Press, the proposed class-action lawsuits were filed in Cook County on Oct. 9 and allege violations of Illinois’ Biometric Information Privacy Act. The complaints claim that the robots’ cameras and LiDAR sensors captured information on customers’ faces and hands as they approached the machines to pick up their orders. Both have denied the allegations.
