Script:

$AllDining = Get-ChildItem -Path "master://sitecore/content/root/Dining" -Recurse

foreach ( $row in $AllDining ) {
    $row.Editing.BeginEdit();
    $row.DisplayName="fff"
    $row.Editing.EndEdit();
    Write-host "title: " $row["DisplayName"];
}
Write-Log $logInfo

Answer 1

You will need to update the following line:

$row.DisplayName="fff"

and replace it with:

$row."__Display Name"="fff"

You should also probably update your Write-Host line as follows:

Write-Host "title: " $row."__Display Name"

Answer 2

$homeItem = Get-Item -Path "/sitecore/content/Home"
$homeItem."__Display Name" = "Sitecore Home"
