Console.WriteLine();

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Machine Name is " + Environment.MachineName);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Operating System Detaiils");

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" OS Version: " + Environment.OSVersion);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Amount of physical memory : " + Environment.WorkingSet);

Console.WriteLine();

Console.WriteLine();

Console.WriteLine(" Number of milliseconds elapsed since system

started:"+Environment.TickCount);
