Issue with Windows Defender on Windows 11
I cannot open any of the settings on windows defender, when i try to it tells me to look for a compatible app in the Microsoft Store. Is this a bug or some other (fixable) issue?
- Aug 07, 2021I had this problem on all machines updated from 19043.1151 to 22000.120.
This command from elevated PowerShell fixed the problem for me, try it and report the results:
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

Has anyone found a fix for this yet? I'm having the same issue. I can't install software for school because Windows Defender keeps deleting the files. The app is working fine and great so why can't we access it? It clearly exists

***FIX FOUND***
[I found a fix everyone!!]
Open PowerShell (as Administrator) and run this command (without the "")
"Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage"
After doing this, check your settings-> Privacy & Security-> Open Windows Security
This should open up Windows defender like it used to on Windows 10. I hope this fixes your problem.

micheluvspinklean just go to start, type to search PowerShell, in right side of window find "Run PowerShell as Administrator" and open it (do not simply open PowerShell icon)
then copy/paste
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
several second and you can open Defender
