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
After a looooot of time, I think I solved this bug.
As I said before, none of powershell command helped in my case, not the on place reinstall.
Today I found a registry key, i.e.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModel\StateChange\PackageList\Microsoft.SecHealthUI_1000.22000.1.0_neutral__8wekyb3d8bbwe\PackageStatus
which was set to 2 (as far as I know, this means the package needs to be reinstalled from the store).
I set it to 0 and now Windows Defender starts and there is no more the error "app not found".
Hopefully this can help other with this tediuos problem.
