Remove Windows Defender from Windows context menu

What if you don’t even use Defender

Microsoft released Windows 10 Fall update this week with. It is running very good on my system. But one pet-peeve I have with the update is that it adds a “Scan with Windows Defender” command in context menus of files and folders. Even if you use a third-party antvirus installed and have Defender disabled. Although one can ignore it and move on with their life, my OCD gets…you know…

I have even removed “Play with Windows Media Player” and “Shop online for music” items. (I use foobar2000.)

To remove the Defender menu item.

Either delete the following registry key:

HKEY_CLASSES_ROOT\CLSID\ {09A47860-11B0-4DA5-AFA5-26D86198A780}

or run the following in elevated Command Prompt:

regsvr32 /u "C:\Program Files\Windows Defender\shellext.dll

…and it will be gone. Poof!
