$ShellApp = New-Object -ComObject Shell.Application
$ShellApp.Windows() | Where-Object {$_.Name -eq 'File Explorer'} | 
Select-Object LocationName,LocationURL

The Where-Object statement is required to filter out results from Internet Explorer. If you are interested in all results including the open Internet Explorer windows and tabs the Where-Object statement can be omitted.
