From Wikipedia, the free encyclopedia
In Windows NT-based operating systems, the System idle process is the system idle task: it tracks how much of the CPU's time is being utilized and issues the HLT instruction to cut the processor's power usage. The percentage of time spent in idle can be seen in the Windows Task Manager.
The process "runs" at a thread priority of 0, ensuring that everything else running on the system has a higher priority and will be able to preempt it. It is also assigned a process id of 0.
