Answer 1

            ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT UserName FROM Win32_ComputerSystem");

            foreach (ManagementObject queryObj in searcher.Get())
            {
                loggedOnUserName = queryObj["UserName"].ToString();
                loggedOnUserName = loggedOnUserName.Substring(loggedOnUserName.LastIndexOf('\\') + 1);
            }

When "User B" is logged on, the application running under "User A" reports "User B" in loggedOnUserName.

That's what I was looking for. Thanks anyways.
