PowerShell V2: Meet New-Object's Property parameter

I've stumbled upon blog post that talks about accessing remote registry, collecting "Automatic Update" configuration info and creating custom object to hold that data for further processing/formatting.
The author has used Add-Member cmdlet to add quite a bunch of NoteProperties to the custom object. In PowerShell V2 we can do it in much cleaner way, with less typing, using new New-Object's Property parameter that expects a hash table as a value, a hash table in which the keys are the names of properties or methods and the values are property values or method arguments.

Let's rewrite a function.

function Get-WSUSRegKey {
   [CmdletBinding()]
   param (
      [parameter(ValueFromPipeline=$true)]
      [String[]]$ComputerName = $env:computername
   )

   PROCESS {
      $ComputerName | ForEach-Object {
      # open remote registry key
      $rootKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine',$_)
      # open subkey WindowsUpdate and its subkey AU
      $regKey0 = $rootKey.OpenSubKey("Software\policies\Microsoft\Windows\WindowsUpdate\")
      $regKey1 = $rootKey.OpenSubKey("Software\policies\Microsoft\Windows\WindowsUpdate\" + $($regKey0.GetSubKeyNames()))

      # create an empty hash table
      $ht = @{}
      # enumerate value names in both subkeys and populate hash table with name/value pairs 
      $regKey0.GetValueNames() | ForEach-Object {$ht.$_ = $regKey0.GetValue($_)}
      $regKey1.GetValueNames() | ForEach-Object {$ht.$_ = $regKey1.GetValue($_)}
      # this will add ComputerName NoteProperty to our object
      $ht.ComputerName = $_
      # and finally, create an object using the data stored in a hash table
      New-Object PSObject -Property $ht
      }
   }
}

Two usage examples:

PS C:\> $servers = 'server1','server2','server3'
PS C:\> Get-WSUSRegKey -ComputerName $servers
PS C:\> $servers | Get-WSUSRegKey | Format-Table ComputerName,WUServer
