How to disable Microsoft Defender (Windows Defender) in Windows 11

If for some reason you need to disable Windows 11 Defender, now called Microsoft Defender permanently or temporarily, you can do it in several ways: manually or by using third-party programs and scripts.

This tutorial details the working ways to disable Microsoft Defender in Windows 11, some of which work permanently, others only disable it temporarily.

Disabling antivirus protection in the Windows Security window

A basic way to disable Windows 11 Defender, which only works for a short time before the system turns it back on, is to use the "Windows Security" interface. Note: if the reason you need to disable the antivirus is because it is deleting files you want, you can simply add folders with them to the exceptions.

Note that the following is your responsibility: A program that Windows Defender won't let you use may not really be worth running. To disable Microsoft Defender in your settings, simply follow these steps

  1. Open the Windows Security window using the icon in the notification area, or Settings – Privacy and Security – Windows Security.
  2. Open protection against viruses and threats.
  3. Under “Virus & threat protection settings”, click “Manage settings”.
  4. Disable «Real-time protection», «Cloud protection», «Automatic sending of samples». If you disable Microsoft Defender to use any software that modifies its operation, please also disable the “Counterfeit Protection” item in the same window.
  5. If any program does not start with the message "Malicious file" after you have done this, please go to "Manage applications/browser" in the "Windows Security" window, open "Reputation-based protection settings" and disable the check and block potentially unwanted applications, and in the properties of the file itself, if it was downloaded from the Internet, check “Unblock” and apply the settings.

This will temporarily disable the antivirus protection features of Microsoft Defender. However, after some time or after a reboot, the protection will be activated again.

Script to completely disable Windows Defender 11

ToggleDefender – A simple bat-script that completely disables all protection features of Windows Defender, SmartScreen filter, notifications and the services they use. One caveat: it can be difficult to turn your antivirus back on after using the script, so I recommend creating a system restore point beforehand.

Using the script to disable the defender:

  1. Go to Windows Security – Virus & Threat Protection – Manage Virus & Threat Protection settings and turn off Tamperproof.
  2. Download the script from the official website
  3. Open the properties of the downloaded file (right click – properties), check the “Unlock” box and click “OK”.
  4. Run the downloaded script.
  5. After a short time, a window will appear with the current status of Windows Defender and a suggestion to disable it: “Turn off Windows Defender?”. Click "Yes".
  6. In a short time (a few seconds, no notifications will appear), the Defender will be completely disabled, but it is advisable to restart the computer as well.
  7. Within the script in the "Personal Configuration Tweak" section there are additional options, such as options to enable and disable sending images to the cloud or protection against potentially unwanted programs, which can be uncommented so that they also apply when using the script.

If you also want to remove the Windows Security icon from the taskbar notification area, simply disable its autorun (read more: How to remove programs from autorun in Windows 11).
