Windows Defender is the default antivirus application for Windows 10. Earlier versions of Windows, such as Windows 8.1, Windows 8, Windows 7, and Vista, also had the application but it was less effective as it only looked for spyware and adware.
In Windows 8 and Windows 10, Defender is application-based Microsoft Security Essentials, which offers better protection by adding full protection against all kinds of malware.
However, if you prefer to use an alternative to protecting your PC, you may want to turn off Windows Defender.
Below we will see how you can do it in the Windows 10 Fall Creators update.
The latest version of Windows 10 is a new application called Windows Defender Security Center or Windows Defender Security Center. The application, formerly known as the Windows Defender Control Panel or Windows Defender Dashboard, was developed to help control security and privacy settings in a clearer and more useful way. Includes all settings related to Windows Defender.
From Windows Defender Security Center, you can temporarily disable Windows Defender in the Windows 10 Fall Creators update, but after a while, it will turn on automatically again. We will see how you can permanently disable Windows Defender in Windows 10.
We will use a tweak in the Registry, with the following code:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows Defender]
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows Defender \ Real-Time Protection]
You can if you want to create your own .reg file (name it as you wish, but make sure it ends with the .reg extension and not .reg.txt) and double-click it to run it on your computer.
Just confirm the UAC query and click Yes to pass the commands to the Registry.
Then you need to restart Windows 10.
The necessary registry configuration files are also available below and you can download them ready. The zip also includes a script to undo the above commands, if at some point you want the application again on your computer.
Note: The Windows Defender icon will not leave the task bar
To hide the icon, you must stop MSASCuiL.exe from startup.
Let's see how you can disable the Windows Defender Tray Center Security Center icon.
Open Task Manager by right-clicking in the lower left corner of your screen. Select Task Manager and in the window that will open select the Startup tab.
Right click and disable or Disable
