Windows 10: You'll need a new app to open this windowsdefender

Hello All,

I try to open anything in the "Windows Security" page in Settings, it prompts me to open it with a new app and the only thing available is the Microsoft Store. I click "Virus & threat protection," and the prompt comes up with "You'll need a new app to open this windowsdefender" and only allows me to choose "Look for an app in the Microsoft Store." The same prompt appears if I try to click any other menu item in Windows Security.


This has been happening since I purchased this computer a couple of months ago. Everything is up to date. Picture below:

You'll need need a new app to open this : windowsdefender

Good Day,

I just got a new computer with a windows 10 home in it. I want to turn off windows defender but I cant seem to turn it off. It gives a pop up that says 'You'll need need a new app to open this : windowsdefender'. This is affecting other window settings I
wish to open as well and it is annoying. Can anyone give me an immediate solution to this? Note it is a NEW windows 10 home. Thanks very much

Chet, doing further research on this found possible solutions in these threads:

So see if opening Defender through Cortana Search box on Task Bar bypasses the error and then sets it right.
