How to Fix Windows Defender Real-time Protection Issues in Windows 11
If you’ve encountered issues turning on or off real-time protection in Windows Defender on Windows 11, you’re not alone. This tutorial will guide you through various methods to resolve these common problems. By following these steps, you’ll learn how to use the Registry Editor, Group Policy Editor, Services, and Windows Updates to ensure your real-time protection settings function correctly. These methods are practical and effective, empowering you to manage your PC’s security seamlessly.
Method 1: Using the Registry Editor
In this method, you will modify certain Registry settings that control real-time protection features. Follow these steps carefully:
- Press the Windows key, type
Registry Editor, and select it from the list to open the Registry Editor. - Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\real time protection. This location contains the settings related to Windows Defender. - You will need to disable the following settings:
- Behavior monitoring
- Real-time monitoring
- Scan on real-time Enable
Make sure to check that no conflicting settings are present. If necessary, delete any inappropriate entries that may be causing issues.
- Once you’ve made the changes, close the Registry Editor.
Method 2: Using the Group Policy Editor
Modifying group policies can help address conflict issues that prevent real-time protection from being toggled. Here’s how:
- Press the Windows key, type
Group Policy, and select Edit Group Policy to open the Group Policy Editor. - Navigate through the following path:
Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus > Real-time Protection. - Find the setting for Turn off real-time protection, double-click it, and then select Not Configured. Do the same for Turn on behavior monitoring to ensure it is also set to Not Configured. Click Apply, then OK.
Method 3: Using Services
Sometimes, the service responsible for Windows Defender may not be running or set to disabled. Here’s how to start it:
- Press Windows + R to open the Run dialog box, then type
services.mscand press Enter. - In the Services window, scroll down to locate the Security Center service. If it shows as disabled or not running, proceed to the next step.
- Right-click the Security Center service, select Start, and set its Startup type to Automatic to ensure it runs whenever your system starts.
Method 4: Checking for Windows Updates
Keeping your system updated can resolve various issues, including problems with real-time protection. Here’s how to check for updates:
- Press Windows + I to open the Settings app.
- Go to Windows Update and then click on Check for updates to see if any updates are pending.
- If updates are available, allow them to install, and then restart your computer to ensure all changes take effect.
