WMI Top Sample

WMI provides per-process processor usage information via the Win32_Process class. The KernelModeTime and UserModeTime properties of this class show the amount of time spent by a process in kernel and user modes respectively. These values show the time spent by the process from its beginning, and therefore cannot be used as a processor usage indicator directly. We have to make two snapshots of these values and then use some simple arithmetic to get processor usage.
