How can I use PowerShell 3.0 cmdlets or script to list all the local groups and local users of a server?

Question

Using PowerShell 3.0 (And if possible the CIM, not WMI cmdlet), how can I script with | out-file C:\<filename>.txt or .csv option to list all local user accounts & local groups
on remote computers? 
Thank You!

I don't recall PowerShell V3 introducing anything new to handle local users and groups. You need to use PowerShell V1 methods, using the [ADSI] accelerator and the WinNT: provider. The scripts linked above show this. No need to use WMI (which would probably
be slower).
Here is a script I've used to enumerate all local groups and their members:
$Computer
= "MyServer"
$Computer =
[ADSI]"WinNT://$Computer"
$Groups =
$Computer.psbase.Children | Where {$_.psbase.schemaClassName
-eq "group"}
ForEach ($Group
In $Groups)
    "Group: "
+ $Group.Name
    $Members
= @($Group.psbase.Invoke("Members"))
    ForEach ($Member
In $Members)
        $Class
= $Member.GetType().InvokeMember("Class",
'GetProperty', $Null,
$Member, $Null)
        $Name
= $Member.GetType().InvokeMember("Name",
'GetProperty', $Null,
$Member, $Null)
        "-- Member: $Name ($Class)"
A similar script to enumerate all local users would be:
$Computer
= "MyServer"
$Computer =
[ADSI]"WinNT://$Computer"
$Users =
$Computer.psbase.Children | Where {$_.psbase.schemaClassName
-eq "user"}
ForEach ($User
In $Users)
    "User: "
+ $User.Name
