Now let’s learn the two methods using which you can turn off Windows Defender permanently.

Permanently Disable Windows Defender Through Registry

Most of the inbuilt Windows 10 programs have their services running at the background. And most of them allow the Windows administrator user to Disable or Enable a service.

Windows Defender also has a service of its own called “Windows Defender Antivirus Service“. But we cannot disable or stop it, as all the options are greyed out. Have a look:

So that’s why we have to go through the Windows registry path. Windows OS registry can be modified to switch off Windows Defender.

You should be very careful when making any changes to the Windows registry as it may break your PC. But do not worry just follow the instructions as it is and everything will be alright.

  • Press Windows Key + R. And type in Regedit in the run window and hit Enter. You will now see the Registry Editor Window in Windows 10.
  • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

  • Now place your mouse pointer on the Windows Defender folder as you see in the above screenshot and then right-click > Export to take a backup (to be on a safe side) in case something goes wrong you can easily restore the registry key.
  • Once you are done with the Windows registry backup, you need to create a new key, right click on the right frame, New –> DWORD (32-BIT) Value.

  • Rename the value with “DisableAntiSpyware“, then double-click on it to edit the value, change it to 1 to disable Windows Defender in Windows 10 permanently.
  • Click OK to save the changes you made.
  • Restart your PC.

Tip: If you are wondering how to turn on Windows Defender in Windows 10 again? Just change the value to ‘0’ (numeric zero) or simply delete the key.

The other method is to modify Group Policy, lets see how to do that.

Group Policy modification is another workaround to Stop Windows Defender permanently. We will use the Windows default Local Group Policy Editor to make changes.

  • Search for gpedit.msc or just press Windows Key + R and type gpedit.msc, hit Enter.
  • Go to Computer Configuration –> Administrative Templates –> Windows Components –> Windows Defender
