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.
