Hi,

We apologize for the delay in response, and for the miscommunication.

Let us try the below steps and check if it helps. 

1. Open an Administrator CMD window.  If you can’t find a way, use these steps:

   • Press CTRL+Shift+ESC to open Task Manager.

   • Click File > Run New Task

   • Make sure you have a check mark beside “Create this task with administrative privileges”

   • Type CMD

2. Type the following commands at the CMD prompt:
       dism /online /cleanup-image /restorehealth
       sfc /scannow

3. If either command does not show a good outcome, we need to stop and repair Windows. See the last step in the procedure.

4. If dism and sfc both completed and show no remaining issues, run these commands:
   powershell
   Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

5. Restart the computer.

Let us know the status, we are glad to assist you further.
