Windows 10: Disable Windows Defender Real-time Protection

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. To disable Windows Defender Real-time protection do these steps:

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

Windows PowerShell
Copyright (C) Microsoft Corporation. All rights reserved.
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
To disable permanently you can use regedit as steps below:

1. Create key Real-Time Protection under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\
2. Create Dword DisableRealtimeMonitoring 1 under HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Real-Time Protection\

It will locked option in Real-time Protection "This setting is managed by your administrator".
Tested on Windows 10 Version 10.0.17134 Build 17134
