full(ish) code, I am inserting the data int a SQL db thus the "inprocs" stuff...
Process[] processlist = Process.GetProcesses();
foreach (Process procs in processlist)
{
if (procs.ProcessName == "System")
{
insprocs.Parameters.Add("@PStart", SqlDbType.NVarChar, 30).Value = startTime.ToString();
}
}
I am currently ToString-ing it for testing but that may/may not remain the case.

If you try to GetProcesses without separating out the "System" (and "Idle")process,even though it is a DateTime, you get the error "System.ComponentModel.Win32Exception: Unable to enumerate the process modules", probably because of the "System" process's starttime properties.

So I am running GetProcesses 3 times-
1) if ((procs.ProcessName != "Idle") && (procs.ProcessName != "System")) // get everything
2) if (procs.ProcessName == "System") // get everything except "MainModule.FileName" (unenumerable for the System process)
3) if (procs.ProcessName == "Idle") // get only ProcessID, ProcessName (I think I can get RAM in use but I am not sure yet)

Depending on how you manipulate the starttime value, you get different values.

long st = procs.StartTime.ToFileTime();
