    If the System *IDLE* process is 100%, what does that mean? That your host
    is 100% IDLE. You'll need to look at the /real/ processes to see which ones
    are spiking.

    Wrong you should see 0% used if its truly idle and nothing is running .
    mine spikes to maybe 25 sometimes 50% but only for short periods then back
    to 0%.

    Did you even look in the Processes tab of Task Manager. All processes are
    to total up to 100% (with some rounding error). If System Idle Process
    didn't take up the slack if remaining (unused) CPU time then the total of
    the CPU column would never be 100%.

    System Idle Process is NOT the same as the System process.

    That is incorrect.

    System Idle Process is not a process or service but a single thread that
    runs on each processor, its sole task is to account for processor idle
    time, or processor time spent doing nothing. If your System Idle
    Process is at or near zero then 100% or narly 100% of the processor is
    being utilized by real processes.

    You've got it backwards.
