Curiosity Technology Computers and Smartphones Windows defender turns on automatically

Tagged: 

  • Hello. I am running Windows 10 Build 1607 Home. I tried disabling Windows Defender by turning off the Real-time protection. But after some time it turns itself on automatically. It takes up too much process and disk when my computer is idle. How do I turn off Windows Defender permanently without group policy?

  • Hi. Welcome to Geekswipe Curiosity. You can disable this by creating a registry key. Open regedit and navigate to this: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDefend. Create a new key with a name DisableRealtimeMonitoring and value as 1.

    You also can do this directly from within PowerShell with the command: Set-MpPreference -DisableRealtimeMonitoring $true

  • The above answer would only disable the real-time monitoring part of Windows Defender. If you want to disable the service entirely, go here HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDefend and change the value of Start to 4. This will disable the service, while changing the value to 3 will change it to manual start. I hope you are aware of the risks involved in disabling it.

    • This is the answer I need. Thanks! No more high disk usage. Screw Microsoft!

    • Yeah screw Microsoft for preventing you from doing stupid things like this. Why do you want to disable windows defender anyway?

    • It is not stupid. I have my reasons to do it. I cant allow defender to take up all the memory and disk when other programs that I use are in need of that. And I know how not to get infected by virus. Whatever I do it is not Microsoft’s call to make choices for me. So screw them for doing that!

    • I have the same build and Windows Defender is working fine. I don’t see any issues. It takes up CPU and disk only when your pc goes idle. This is the expected behaviour. It is automatic for your own safety. Disabling it is still stupid.

    • Good for you. I bought the OS by paying my money here. So I will decide how my operating system should be. You can stop caring about my safety now.
