When the computer is doing nothing, then that percentage is high.

To find out what each Startup(or Process) item
does or means, and any recommendation as to if you should close the process:

You cannot end it, it is an essential to the correct operating of the computer.

System Idle Process is what the CPU does when it has nothing else to do, which believe it or not, is most of the time. Like a motor car standing at traffic lights with the engine on tick-over waiting for the lights to change.

By CPU I mean that big chip strapped to the motherboard with a fan and heat-sink on it, not the whole computer as some seem to think,

On most computers System Idle Process is showing something in the region of 95% so 80% means that the CPU is being kept pretty busy by something else.

Without some more information it is only guess work. Look at other processes ans see if they are taking up an inordinate length of time. As I said previous, %80 is a low figure for System Idle Process. Something else is taking up CPU cycles.

One thing you can be sure of, it is not System Idle Process that is slowing down your computer.

Then clean up your computer.

Most Virus and Spyware scans are likely to work better in Windows Safe-Mode.

You can do Start, then RUN, then type
msconfig
Then uncheck items in the Startup tab.

I have been seeing responses such as this for a few years now. But no one has ever explained why (1) if the computer is doing nothing, why is the hard drive working up a major sweat while doing nothing; and as an outgrowth of this, (2) why, if the computer is doing nothing, it locks me out from performing any task whatsoever until the hard drive stops (which on occasion may be up to 4-5 minutes).

I think the useful answer lies somewhere in that while the computer is idling, it is performing background housekeeping tasks which have been deferred while the machine is in use. Thus, the real question is, how to I instruct/prevent the machine from performing these tasks until I am no longer trying to use it (i.e., at lunch or overnight). This is a different issue from actually disabling the system idle process altogether.

Anyone have any thoughts on this?

System Idle Process only relates to the CPU itself, not the rest of the computer. The CPU is idle while it is waiting for the memory to catch up, waiting for the hard disk to do its thing, the graphics process to process information. All these things take time and while they are busy, the CPU has nothing to do.

As stated earlier, a CPUs spend 80% of its time doing nothing while the other bits of the computer are busy doing there thing. If you get locked out for 4-5 minutes you have another problem unrelated to System Idle Process - some badly written software that is taking too many CPU cycles

If by some chance you did manage to disable System Idle process the computer would come to a grinding halt in milliseconds as the CPU loses synchronisation with the rest of the system. That is all System Idle Process is doing, executing NOP commands just to keep it in sync with the rest of the system.
