Retrieve the list of stopped stervices using the Windows Management Interface (WMI)

Use the ManagementObjectSearcher to query the list of stopped services in Win32.

The code block below shows you how:

List<string> runningServices = new List<string>();

ManagementObjectSearcher moSearcher = new ManagementObjectSearcher(""SELECT * FROM Win32_Service WHERE Started = False"");

foreach (ManagementObject service in moSearcher.Get())
runningServices.Add(service[""Caption""]);
