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?
- I 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
Here is the solution given by fggIB and it works for Windows 11 Home 21H2 Build 22000.160:
This is awesome!
Run Powershell as admin and paste the following:
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage
I just copied and pasted it into elevated PowerShell (run as admin) and it worked! I initially thought there would be a need to restart or any notifications but this worked straight.
For beginners, search for PowerShell on Windows, right-click and select "Run As Administrator", accept the prompt. Copy the above and paste it there, a very fast text will pop up and leave. Try opening the Windows security again.
