[RUN THIS AT YOUR OWN RISK - NO GARUNTEES /-wz]

These issues might be occuring due to some System files missing. You can try below steps and check if it helps:

A.         Check for software that may be causing issues for the Windows user interface. If you find any of the below, please remove it as a test to see if the symptom changes:

1.         IDT Audio

2.         Norton Antivirus

3.         Other software in Programs and Features that is likely to hook into the shell.

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

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

2.         Click File > Run New Task

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

4.         Type CMD

C.         Type the following commands at the CMD Prompt, Enter:    

dism /online /cleanup-image /restorehealth    ( Make sure a space is between each / after the last command word.)

{and at the blincking cursor, wait...(go to lunch time) for completion message...}

Eventually, if it works: [==========================100.0%==========================] The restore operation completed successfully.

 Then upon that completion, at the Command Prompt, type in:

sfc /scannow

{Enter, and wait...for completion message...} 

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"}
