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

 

"You'll need a new app to open this windowsdefender" error

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.

 

Mail app will not open on 10041.


Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)
