    $GivenName = [System.Globalization.CultureInfo]::CurrentCulture.TextInfo.ToTitleCase("$($_.givenname)".ToLower())
    $SurName = $
    $DisplayName = "$SurName $GivenName"
    Set-ADUser -Identity $_.samaccountname -DisplayName $DisplayName -GivenName $GivenName -Surname $SurName
    Get-ADUser -Identity $_.samaccountname | Rename-ADObject -NewName $DisplayName
    $GivenName = $SurName = $DisplayName = $null
