Why do we disable Windows Defender on Windows 10

Windows Defender is infamous for its tendency to monopolize CPU and I/O resources. Moreover, some of its “security” measures are undesirable and may put user privacy at risk. This has many practical consequences, such as:

slower general operation due to increased resource usage,
excessive CPU usage while copying files, slowing down the entire system,
increased heat and noise output, as well as reduced battery life on laptops,
deletion of files detected as “malware” without the user’s consent, even in ZIP archives or on attached network drives,
user privacy at risk, due to automatic sending of “malware samples” to Microsoft,
…
Windows 10 allows you to disable Windows Defender in the Settings, but this is only temporarily effective; it will be automatically re-enabled eventually – the exact timing for this is random and unpredictable.

This repository contains a “disable” .reg file which can be used to permanently disable Windows Defender. But don’t worry, you can revert it using the included “restore” .reg file.

“This really opened my eyes to AD security in a way defensive work never did.”

Attackers know Windows Defender can detect cyberattacks, so as part of their standard playbook they attempt to disable Defender. Sometimes they could use group policy to disable Windows Defender on multiple machines – depending on their level of access – so they can move more easily between several computers on your network. Sometimes they will use a local group policy to disable Defender. There are other methods attackers use to disable Defender, but the group policy method makes it more difficult for the user to re-enable it.

5 Solutions for Windows Defender Turned Off by Group Policy

If you experience or one of your user’s reports this kind of error, you have several options to re-enable Defender. As a security practitioner, you might want to check several of these settings and a few other items (i.e., malware, AD event logs, ) for evidence of tampering.

Solution 1: Using Group Policy

  1. Open Group Policy editor
  2. Select Local Computer Policy -> Administrative Templates -> Windows Components
  3. Select Windows Defender and in the right panel and double click the setting “Turn off Windows Defender”
  4. “Turn off Windows Defender” should be set to Enable if you can’t run Windows Defender. You want to disable this option. You will need local administrative rights to make this change

You should be able to run Windows Defender after you update this GPO.

Solution 3: Using the Command Line

Another solution is to run the following command from PowerShell – make sure to Run As Administrator.

Solution 4: Using the Registry Editor

Editing the Registry is another possible fix for this issue.

  2. Navigate through the tree to HKEY_LOCAL_MACHINESoftwarePoliciesMicrosoftWindows Defender.
  3. Delete DisableAntiSpyware in the right pane.
