Turning off Windows Defender in Windows 10 RRS feed

  • Question

  • Hi,


    In some scenarios, we need to turn off Windows Defender.


    In Windows 10, components of Windows Defender are Real-time protection, Cloud-delivered protection, Automatic sample submission, Tamper protection and Ransomware protection.


    Generally, we do turn off Real-time protection, Cloud-delivered protection, Automatic sample submission and Tamper protection for turning off Windows Defender.

    Real-time protection gets turn on automatically. Moreover, if I allow any app for running in the device, it always gives notifications, even if I allowed.

    Can it be resolved?

    With Regards

    MrGNS

  • Try it using Powershell or Command Prompt

    There are two commands each to turn real-time protection on or off. Open either PowerShell or the Command Prompt.

    While these commands have been around for years, they didn't work for us when testing for this tutorial.

    Command Prompt:

    On - PowerShell Set-MpPreference -DisableRealtimeMonitoring 0 or PowerShell Set-MpPreference -DisableRealtimeMonitoring $false
    
    Off - PowerShell Set-MpPreference -DisableRealtimeMonitoring 1 or PowerShell Set-MpPreference -DisableRealtimeMonitoring $true

    PowerShell:

    On - Set-MpPreference -DisableRealtimeMonitoring 0 or Set-MpPreference -DisableRealtimeMonitoring $false
    
    Off Set-MpPreference -DisableRealtimeMonitoring 1 or Set-MpPreference -DisableRealtimeMonitoring $true

    Hope this helps!

  • Hello,

    Have you tried turning off Windows Defender Antivirus using Turn off Windows Defender Antivirus setting at Computer configuration > Administrative templates > Windows Components > Windows Defender Antivirus? Try this and see if it makes any differences.

    Note: You must turn off Tamper protection before configuring above mentioned policy.

    Regards.

  • I am sorry to say, I didn't find it

    Computer configuration > Administrative templates > Windows Components > Windows Defender Antivirus

    Pls assist me to find this option in Windows 10.

    I found this option. Am I at right step?

    Moreover, if I allowed an application to run in this device, why I get notification? Can I resolve it?

    Regards

  • Hello,

     

    This option is not in Local Security Policy, please type Local Group Policy Editor in search tab.

    And you can try this method:

    1. Open setting and select System
    2. go to the Notifications & Actions section
    3. To turn off all notifications from apps, move the Get notifications from apps and other senders slider to the Off position.
    4. To choose which apps are allowed to interrupt you, scroll down to the section headed Show Get notifications from these senders. Move the slider for an individual app to the Off position to silence all notifications from that app or feature.

     

    Best regard,

    Slylvia
