This worked for me. The MiniTool instructions.
Background: at first when I went into powershell (admin not needed to list them) and type:
In the resulting list of 29 items,Code:Get-AppxPackage | ftMicrosoft.Windows.SecHealthUI
was NOT listed. It was totally missing.
So none of the more common "re-register" steps would work because they requireGet-AppxPackage
to see it and on my system it couldn't.
But the MiniTool approach gets at it from the file location on disk:
C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy
This WAS there on my system.
So, opening powershell admin (right click start menu) and running MiniTool's suggestion, namely,
fixed it. It essentially reinstalled it. Then it appeared in the list returned fromCode:Add-AppxPackage -Register –DisableDevelopmentMode "C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\AppXManifest.xml"Get-AppxPackage
and the "Open Windows Security" button in settings worked.
