If you are facing a problem with Windows 10 with a pop-up message as below that keeps on prompting even though you continuously clicked on the OK button, here is the fix.
Right click on the Windows icon on the left of taskbar, and run Windows PowerShell as admin.
Copy and paste the following command to run in the Windows PowerShell admin console.
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
Hopefully after this, your problem will be fixed.
