$JoursInactivite = 90

# Récupérer les ordinateurs inactifs
$OrdinateursInactifs = Get-ADComputer -Filter {LastLogonTimeStamp -lt (Get-Date).AddDays(-$JoursInactivite)} -Properties LastLogonTimeStamp

# Créer un rapport des ordinateurs à supprimer
$Rapport = @()

foreach ($Ordinateur in $OrdinateursInactifs) {
    $Info = [PSCustomObject]@{
        Nom = $Ordinateur.Name
        DernièreConnexion = $Ordinateur.LastLogonTimeStamp
        JoursInactif = ((Get-Date) - $Ordinateur.LastLogonTimeStamp).Days
    }
    $Rapport += $Info
}
