            # critical services
            "DcomLaunch" { "Critical: Should always be running." }
            "RpcSs" { "Critical: Should always be running." }

        "XblGameSave", "XboxGipSvc", "XboxNetApiSvc", "MapsBroker", "lfsvc"

    foreach ($service in $servicesToStop) {
        Stop-Service -Name $service -ErrorAction SilentlyContinue

    }
 
    Write-Output "Recommended changes applied. Services stopped and disabled."
}

function Restore-Services {
    param([string]$BackupFile)
    
    $backup = Import-Csv -Path $BackupFile
    foreach ($service in $backup) {
        $currentService = Get-Service -Name $service.Name -ErrorAction SilentlyContinue
        if ($currentService) {
            if ($service.Status -eq "Running") {
                Start-Service -Name $service.Name -ErrorAction SilentlyContinue
            } else {
                Stop-Service -Name $service.Name -ErrorAction SilentlyContinue
            }
            Set-Service -Name $service.Name -StartupType $service.StartType -ErrorAction SilentlyContinue
