Disable Windows Defender in Windows 10 Fall Creators Update

Windows Defender is the default antivirus app shipped with Windows 10. Earlier versions of Windows like Windows 8.1, Windows 8, Windows 7 and Vista also had it but it was less efficient previously as it only scanned spyware and adware. In Windows 8 and Windows 10, Defender is based on the Microsoft Security Essentials app which offers better protection by adding full blown protection against all kinds of malware. However, if you prefer to use alternative solution for protecting your PC, you might want to disable Windows Defender. Here is how you can disable it in Windows 10 Fall Creators Update.

Note: This will not remove the Windows Defender icon in the system tray:

To hide the icon, refer to the following article:

Recent Windows 10 version come with is a new app called Windows Defender Security Center. The application, formerly known as "Windows Defender Dashboard", has been created to help the user control his security and privacy settings in a clear and useful way. It includes all the settings related to Windows Defender. See the following article: Windows Defender Security Center in Windows 10 Creators Update.

It is possible to use Windows Defender Security Center to temporarily disable Windows Defender in Windows 10 Fall Creators Update. After some period of time, it will be re-enabled automatically. For some users, this solution is suitable. Here is how it can be done.

  1. Open Notepad and paste the following text into a new text document:
    Windows Registry Editor Version 5.00

    Although security has always been a priority for Microsoft, before Windows 10 it took the company several years to release new versions of the OS, making the response to new threats very slow. In order to help commercial customers deliver mitigations against specific vulnerabilities, Microsoft created the Enhanced Mitigation Experience Toolkit (EMET), which allowed customers to keep devices secure without waiting until the next version of Windows.

    On a low-end computer, this is a must. Defender severely cripples already weak computers. I use BitDefender FREE version on Creators Update, not sure if it’s compatible with FCU yet, it’s very basic but doesn’t impact performance. For an extra layer of protection I also use BitDefender Anti-Ransomware, also a free product.

      To fully disable WD, you should also disable its services.

      reg add “HKLM\System\CurrentControlSet\Services\WdBoot” /v “Start” /t REG_DWORD /d “4” /f
      reg add “HKLM\System\CurrentControlSet\Services\WdFilter” /v “Start” /t REG_DWORD /d “4” /f
      reg add “HKLM\System\CurrentControlSet\Services\WdNisDrv” /v “Start” /t REG_DWORD /d “4” /f
      reg add “HKLM\System\CurrentControlSet\Services\WdNisSvc” /v “Start” /t REG_DWORD /d “4” /f
      reg add “HKLM\System\CurrentControlSet\Services\WinDefend” /v “Start” /t REG_DWORD /d “4” /f
