Using WMI and Win32_QuickFixEngineering you can get all the hotfixes that are installed on the system.

const string query = "SELECT HotFixID FROM Win32_QuickFixEngineering";
var search = new ManagementObjectSearcher(query);
var collection = search.Get();

foreach (ManagementObject quickFix in collection)
    Console.WriteLine(quickFix["HotFixID"].ToString());
