User Account Settings Closes When Adding an Account or Switching to MS Account

If the User Accounts Settings page closes abruptly when trying to create a new user account or when switching your local user account to Microsoft account, here is a couple of PowerShell commands to fix the problem.

The above screen may show up for a couple of seconds and close abruptly without showing an error. As a result, you’re unable to create a new user via the user interface.

Reinstall User Accounts Settings Panel

Start PowerShell.exe and run the following command, exactly as given:

Get-AppxPackage Microsoft.AccountsControl | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

And then run this command:

Get-AppxPackage Microsoft.Windows.CloudExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

This reinstalls the package for User Accounts Settings page.

That should fix the issue.
