WUSU - Update issue

Seems I still find a lot of these systems that were managed by 2011 small buiness server where the server has been removed from the domain but the WUSU settings were not removed from the GPO correctly leaving one or more systems looking for a server that no longer exist. This script removes and reset the update service back to default on the client. 

Suggestions/Comments?

# Stop the Windows Update service
Stop-Service -Name wuauserv

# Remove the registry key
Remove-Item `
    'HKLM:\Software\Policies\Microsoft\Windows\WindowsUpdate' `
    -Recurse

# Start the Windows Update service
Start-Service -Name wuauserv
