To permanently disable Windows Defender on your Windows machine, you can use one of the following methods: using the Registry Editor or the Group Policy Editor, depending on your version of Windows. Here are the steps for both methods:

Method 1: Using the Registry Editor (For Windows Home and Pro)

1. Open the Registry Editor:
   
   • Press Windows + R, type regedit, and press Enter.
     
   • Confirm any prompts to open the Registry Editor.
     
2. Navigate to the Windows Defender Key:
   
   • Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender.
     
3. Create a New DWORD Value:
   
   • Right-click on the Windows Defender folder, select New, and then DWORD (32-bit) Value.
     
   • Name the new value DisableAntiSpyware.
     
4. Set the Value:
   
   • Double-click on DisableAntiSpyware and set its value to 1.
     
   • Click OK to save the changes.
     
5. Restart Your Computer:
   
   • Restart your computer to apply the changes. Windows Defender should now be permanently disabled.
     

Method 2: Using the Group Policy Editor (For Windows Pro and Enterprise)

1. Open the Group Policy Editor:
   
   • Press Windows + R, type gpedit.msc, and press Enter.
     
2. Navigate to Windows Defender Settings:
   
   • Go to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus.
     
3. Disable Microsoft Defender Antivirus:
   
   • Double-click on Turn off Microsoft Defender Antivirus.
     
   • Select Enabled and click Apply, then OK.
     
4. Restart Your Computer:
   
   • Restart your computer to apply the changes. Windows Defender should now be permanently disabled.
     

Additional Steps to Ensure Permanent Disabling

• Disable Tamper Protection:
  
  • Open Windows Security from the Start menu.
    
  • Go to Virus & threat protection > Manage settings.
    
  • Turn off Tamper Protection.
    

Please do let me know if the method I suggested works for you or if you need further assistance.

 

Permanently Disable Windows Defender?

Since this is a TP. The option to turn off/disable Windows Defender is grayed out. However, you can turn off by:

1. Open Admin Command Prompt and type: gpedit.msc
2. Manoeuver to: Computer Configuration->Administrative Templates->Windows Components->Windows Defender
3. Double click on "Turn Off Windows Defender" and select "Enabled" then click "Apply"

WARNING: After turn off "Windows Defender", you might not be able to turn it back on. I suggest before trying this, make a backup image so you can restore to the way it was.

 

Windows Security Issue: Missing 'windowsdefender' in Windows 11 24H2 (26100.863)

Chewed on this for a day. My first post as well. Hopefully this finds people in the same boat.

Known issue

New Windows 11, version 24H2 devices that are intended to be onboarded to Microsoft Defender for Endpoint might require customers to enable the prerequisite feature. This affects all supported architectures.

IT admins might observe devices not being able to be onboarded to the Defender for Endpoint cloud service, and not receiving the expected protection as a result, even if Intune is expected to execute the onboarding sequence by applying an endpoint detection and response (EDR) policy. Intune will also display an error as it is unable to successfully apply the policy. Users may also not be able to connect to corporate resources if a Conditional Access policy is configured to require Defender for Endpoint being enabled and actively reporting in. Compliance status is visible in the Microsoft Intune device compliance dashboard. This might happen in one of the following scenarios.

• A user buys a new device that has the Home SKU. This SKU does not support Defender for Endpoint. Then the user upgrades to Pro using a Pro product key. This process, called “transmog,” does not install Defender for Endpoint, which is by design. The Defender for Endpoint agent is not correctly enrolled in the Defender for Endpoint service, and the device is not protected.
  
• A user buys a new device that has the Pro SKU, and the OEM did not install the required feature.
  

Important Defender for Endpoint has been removed from the base image for Windows 11, version 24H2 and needs to be manually installed whenever a device goes from Home to Pro.

Workaround

Use the Deployment Image Servicing and Management (DISM) command-line tool to install the Windows Sense Client from an elevated command prompt. See the command below.
