Enable / disable Periodic Scanning feature in Windows 10

Starting with Windows 10 build 14352, a new security setting called Limited Periodic Scanning was included.

What is the Limited Periodic Scanning?

Limited Periodic Scanning is a new privacy setting that you can choose to enable if you use an antivirus program other than Microsoft Defender. This setting can provide an additional line of defense in scanning and detecting malware on the device. Every month, Microsoft’s Malicious Software Removal Tool (malware removal tool) detects malware on 1 to 2 million devices, even those running other antivirus software.

When enabled, Windows 10 uses the Microsoft Defender scan tool to periodically scan your PC for threats, then address them. These periodic scans will use Automatic Maintenance to ensure the system chooses optimal times, based on minimal user impact, PC performance and energy efficiency or the customer can schedule times scan this. The Limited Periodic Scanning aims to provide an additional line of defense for the real-time protection you already have with your antivirus program.

With Windows 10’s Limited Periodic Scanning enabled and even if you’re not using Microsoft Defender for real-time protection, the Microsoft Defender UI and History tab will let you see any additional threats already detected.

When a threat is detected, Microsoft Defender will notify you with a Windows 10 message. In most cases, Windows Defender will also take action on the threat automatically. Clicking on the notification will open Microsoft Defender, where you can further review the detected threat and the action is taken automatically.

Clicking on the notification will take you to Windows Security, where additional actions can be taken and applied (if needed).

This guide will show you how to enable or disable the Periodic Scanning feature with Microsoft Defender Antivirus, once you have installed a third-party antivirus program in Windows 10.

Note: You must be logged in as an admin to be able to enable or disable the Limited Periodic Scanning feature.
