System and System Idle Process do that, no matter what version of Windows. And the CPU usage you think you see is actually kernel CPU usage, set aside specially. It doesn't use up your CPU, though. I'll guess you're using XP, and you may be running other tasks. Or your computer could be like mine, and the System Idle Process will use up you CPU after coming out of standby with no remedy except to restart every time.
One word for you, troll. GTFO lol He's right =]
that's what he's saying it does nothing when you start a program the CPU usage for that goes down as that goes up that's what lucasbytegenius was saying
The fact is that most computers can never really do nothing. When the computer is on, the CPU's running and it must do something - even if that "something" is waiting for something real to do.
Think of it as your computer just twiddling its virtual thumbs, waiting for something more important to do. The computer's doing something (virtual thumb twiddling), but we wouldn't call that doing anything useful.
Did you read anything i've posted >.>
