In Windows NT-based operating systems, the System Idle Process is the system idle task: it measures how much idle capacity the CPU has at any given time. The process runs in the background and constantly monitors processing bandwidth, occupied memory and the Windows virtual paging file.
So basically, no. That's how much CPU power is unused.
I always used to wonder about that years ago, but its totally self explanatory when you think about it. If you said "oh raffaz is idle", you would be meaning that i was sitting on me arse doing nothing
the idle proccess is to take up all the time that your cpu isnt being used because your cpu must always be receiving threads otherwise it will have to reboot.
i guess this is kinda out there but if your an overclocker and you freeze your system that is why hitting the reset button wont work. the cpu has to completely restart. when you hit the reset button all it does is rerun the startup through the BIOS settings but the cpu is still reciving threads throughout this whole process
