How do I check regional and language settings for reserved accounts

Hi All,

I urgently need to use powershell to check the regional and language settings for "reserve accounts" on Windows 2008 32/64 bit boxes.
 
Reservered Accounts defined in Windows 2008 as follows:
Dafult User (New Users)
System Accounts (Local System, Local Service, and Network Service)

I can already use "Get-Culture" commandlet to get the regional and language settings for the current user. More crucially I need to findout what has been set for the Reserved Accounts.

Thanks in advance
