Microsoft Warns ATP Customers About Latest Windows 10 Update

News Windows 10 Update Atp Featured

Windows 10 is continuing to have update issues. Throughout the past few months, it seems it’s just been one problem after the next.

The KB4520062 cumulative update for Window 10 that was released on October 15 could bring harm to the Windows Defender Advanced Threat Protection (ATP) service for enterprise-based customers according to a warning released by Microsoft.

Microsoft’s Warning

If you use Microsoft Enterprise for your business as well as ATP, you need to heed the company’s warning to keep your business safe, though Windows 10 Home and Windows 10 Pro users do not need to worry about the Windows Security platform.

“After installing this update, the Microsoft Defender Advanced Threat Protection (ATP) service might stop running and might fail to send reporting data,” warned the company.

“You might also receive a 0xc0000409 error in Event Viewer in MsSense.exe.”

Microsoft adds that it’s “working on a resolution” for its paid service for detecting and handling advanced threats. However, it doesn’t expect an official fix to be released until the middle of November, so Enterprise customers using ATP should not install the update until the fix is released.

If the KB4520062 cumulative update is already installed by ATP customers, the issues may already be happening. These users should uninstall the update.

This is not the only recent problem updating Windows recently. A September 16 update broke Windows Defender, while an October 3 update caused Start Menu problems and broke the print spooler. The Start Menu still wasn’t fixed with the October 8 update.

The servicing stack update released on October 8 improves the reliability of the update process and should be installed by all users, however.

Fixes and Improvements

The KB4520062 cumulative update does bring many fixes and improvements. It handles an issue that caused high CPU usage while multiple windows are open when the Background Application menu runs a scan.

It also solves a Bluetooth issue that involves incorrectly-named Microsoft SharePoint files, the Settings app ceasing to work after changing a theme, the Start menu not showing blank tiles, high power consumption for devices in Standby mode, and a “15-5” error generated with the Windows Mixed Reality Portal.
