Windows 10: Untable to Control Windows Defender Real-time Protection On/Off

Sometimes, we need to turn off Windows Defender Real-time protection. In my experience, this software may cause some error to run Android Emulator such as BigNox. It also slowing down my Android Studio. To disable Windows Defender Real-time protection, I do these steps:

1. Run Windows PowerShell as administrator
2. execute set-mppreference -DisableRealtimeMonitoring 1

Windows PowerShell

PS C:\WINDOWS\system32> set-mppreference -DisableRealtimeMonitoring 1

PS C:\WINDOWS\system32>

In Windows registry it will create

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Real-Time Protection -> DisableRealtimeMonitoring REG_DWORD 1

Tested on Windows 10 Version 10.0.17134 Build 17134


But, during my computer idle, windows always put Real-time protection on. It is so annoying. I want to control Real-time Protection manually.

Defender will only do periodic scanning, no real time protection

Hello,

This issue may happen if other security software, such as antivirus, anti-spyware, or anti-malware programs, are fully or partially installed on the computer. Windows Defender automatically turns off if you install another antivirus app.

Let us uncheck security messages for Virus Protection and Spyware, kindly follow the steps below:

• Press the Windows key + X, then select Control Panel.
• Click on Security and Maintenance.
• Click the Change Security and Maintenance Settings.
• Uncheck Spyware and unwanted software protection and Virus Protection.
• Click OK.
• Restart the device for the changes to take effect.

After the device restarted, make a full system scan using Windows defender.

To turn on real-time protection, do the steps below:

• Select the Start button, then select Settings.
• Click on Update & Security > Windows Defender.
• Turn on Real-time protection.

Update us on the results.

Regards.
