Windows 10: How to add-appxpackage -register appxmanifest.xml

How to fix this issue?

:)

 

Timeline under PEOPLE shows nothing

It's possible that some system files for the People app needs to be re-registered. To do that, we suggest following these steps:

• 
  Right-click the Start button.
  
• 
  Click Command Prompt (Admin).
  
• 
  Copy and paste the following command: PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *People*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage
  -DisableDevelopmentMode -Register $manifest}" and press Enter.
  
• 
  Once it's finished, close the Command Prompt and check if Timelines are available on the app.
  

Gice us an update on what happens after re-registering the People app.

 

The MiniTool register from disk worked for me

This worked for me. The MiniTool instructions.

Background: at first when I went into powershell (admin not needed to list them) and type:

Code:

In the resulting list of 29 items, Microsoft.Windows.SecHealthUI was NOT listed. It was totally missing.

So none of the more common "re-register" steps would work because they require Get-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,

Code:

fixed it. It essentially reinstalled it. Then it appeared in the list returned from Get-AppxPackage and the "Open Windows Security" button in settings worked.

 

AppXManifest missing

Sorry that I mislead you, I mean I got the error when I put in the console command to check the healthiness of my windows installation

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml" -Verbose} in Powershell

.

I have already tried your suggestion above inside and outside of safemode, each of which the console said that it could not fix my problem. I simply need a way to get a copy of AppXManifest to where it
is supposed to be and I think that should fix it. The problem is that I do not know how to acquire one such file, nor where to put it.

If this helps, the dism command stopped half way (43.9%) and said that it could not go on. Sfc said that it could not fix the problem after it reached 64%.
