Idle is a state that a computer processor is in when it is not being used by any program. Every program or task that runs on a computer system occupies a certain amount of processing time on the CPU. If the CPU has completed all tasks it is idle. Modern processors use idle time to save power.
However, the idle process does not use up computer resources (even when stated to be running at a high percent). Its CPU time "usage" is a measure of how much CPU time is not being used by other threads. In Windows 2000 and later the threads in the System Idle Process are also used to implement CPU power saving.
Windows Vista introduced a hybrid sleep feature, which saves the contents of memory to hard disk but instead of powering down, enters sleep mode. If the power is lost, the computer can resume as if hibernated. Windows 7 introduced compression to the hibernation file and set the default size to 75% of the total physical memory. [18]
