How to disable Windows Defender temporarily or permanently

There is no option to uninstall Windows Defender, but you can disable Windows’ built-in antivirus to perform an action that does not allow you or you want to do without it. Here I will show you how to disable Windows Defender, either temporarily or permanently in Windows 10.

The antivirus Windows Defender is designed to protect Windows 10 and your data from viruses, ransomware, spyware and many other forms of malware. It can even protect you from hackers or hackers. But if you want to shut down or deactivate Windows Defender permanently or temporarily, you can do it in 3 different ways: using group policies, the Registry or the Windows Security application.

1. Temporarily disable Windows Defender in Windows Security

If you need to disable Windows Defender in order to perform a specific task, you don’t need to permanently disable it. This is what you should do to disable Windows Defender temporarily:

# 1. Open the Start menu , search  for Windows Security  and click on the main result to open the application.

# 2. Click on  Antivirus and Threat Protection.

# 3. Scroll down to the Antivirus and Threat Protection Settings section and click on the Manage settings option  .

# 4. Here you can disable Windows antivirus by turning off the switch under the Real-time protection option .

In this way the antivirus will disable real-time protection. This will allow you to install applications or make a specific change to the system that you could not do before because the security function was blocking the action.

To reactivate Windows Defender again, restart your computer or use the same instructions described above. In the latter case, make sure to activate the switch under the Real-time protection option .

2. Disable Windows Defender using Group Policies

In Windows 10 Pro, you can use the Local Group Policy Editor to permanently disable Windows Defender. But you must first disable Tamper Protection before doing so. Otherwise, the security function will restart automatically on the next system reboot.

Disable Tamper Protection

To disable Tamper Protection use these steps:

# 1. Follow the first 3 steps of the above procedure.

# 2. Turn off the switch under the Tamper Protection option  .

After doing this you can proceed to disable Windows Defender Antivirus permanently through group policies.

How to turn off Windows Defender

Now you can disable Windows Defender Antivirus permanently with these steps:

# 5. Restart the computer for the changes to take effect.

Windows 10 antivirus will be permanently disabled, although you will still see the shield icon on the taskbar, which is completely normal. This is because the icon is part of the Windows Security application, not the antivirus.

If you need to revert the changes, you can reactivate Windows Defender using the same instructions described above. The difference is that in step 5 you must select the Not configured option  . And don’t forget to re- enable the Tamper Protection feature using the procedure above.

3. How to disable Windows 10 antivirus in the Registry

If you don’t have access to the Local Group Policy Editor, you can permanently disable Windows Defender through the registry.

WARNING: Modifying the Registry is risky and can damage your system if you don’t do it correctly. To reduce this risk, you should make a  backup copy of the Registry before continuing.

# 1. You must first disable Tamper Protection using the steps shown in the procedure above.

# 2. Open the Start menu , search for  regedit,  and click the main result to open the Registry Editor.

# 3. Then go the following route:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

You can copy and paste the path into the Registry address bar to quickly jump to the destination key.

# 4. Right- click inside the Windows Defender key (folder), select  New,  and click  DWORD Value (32-bit).

# 5. Name the new password  DisableAntiSpyware  and press the Enter key .

# 6. Now double click on the newly created DWORD value, change the value from 0 to 1, click OK and Restart the system.

In this way, you will have disabled Windows Defender, so Windows’ built-in antivirus will no longer protect your system against malware.

If you want to revert the changes and reactivate Windows Defender, you can use the same instructions described above. In step 6, right-click on the DisableAntiSpyware key   and select the Delete option.
