So this all started because I was unable to open the Windows Security Center. It just wouldn’t open.

I tried to open SecHealthUI.exe directly (C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI*\) and that failed out. Eventviewer showed Faulting application name: sechealthui.exe, faulting module name: KERNELBASE.dll. Someone wanted me to re-run the kernelbase.dll registry (regsvr32 kernelbase.dll) which doesn’t do anything unless you give yourself administrative privs to the kernelbase.dll file. And didn’t fix my issue anyway.

What did help me was re-installing all of the Windows Apps with the following powershell command:

• windows key + x
• Select Windows Powershell (Admin)
• Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• Profit

And, because this is entitled “Widnows Apps”..

• Uninstall XBox Windows-related items
• Select Windows Powershell (Admin)
• Get-AppXPackage *xboxapp* -AllUsers | Remove-AppXPackage
