Answer 1

Using powershell I did it very perfectly with the script from social.msdn.microsoft.com/Forums

Here is sample code, Tyepe "YES" to proceed once prompted. and Replace the only two variable: (urlToTheYourSite & YourListNameToDelete)

write-host "This will delete data, type YES to continue"
$retval = read-host 
if ($retval -ne "YES") 
{
    write-host "exiting - you did not type yes" -foregroundcolor green
    exit
}
write-host "continuing"

$web = get-spweb https://urlToTheYourSite
$list = $web.lists | where {$_.title -eq "YourListNameToDelete"}
Write-host "List $($list.title) has $($list.items.count) entries"
$items = $list.items

foreach ($item in $items)

{
    Write-host "  Say Goodbye to $($item.id)" -foregroundcolor red

    $list.getitembyid($Item.id).Delete()
}

Answer 2

Here is a summary of what you could try to do:

$spWeb = Get-SPWeb -Identity http://yourdomain/sites/config
$spList = $spWeb.Lists["AppSettings"]
$spItem = $spList.GetItemById(10013) //or another way that you prefer.
$spItem["Name"] = "MyName"
$spItem.Update()
