When I use iTunes, it makes my computer use 100% CPU, but the task manager says it is in the "System Idle Process", which in the past has indicated to me that there is a problem with the drivers. It cripples all my activity on the computer and is virtually unusable. I love iTunes so this is disappointing. I have uninstalled and reinstalled to no avail. How should I continue?

    Odd. The System Idle Process indicates the unused percentage of the CPU. So, taken at face value, a System Idle Process of 100% indicates that your processor is zeroing out, rather than maxxing out.

    In Processes, is the sum of System Idle process and the other processes adding up to more than a 100%? If so, does perfmon give a clearer idea of whether or not the system is maxing or zeroing when iTunes is launched?

    See:

    Task Manager may not calculate CPU usage correctly on Windows 2000, Windows Server 2003, or Windows XP

    I have the same problem, after that I have updated iTunes to the 7.7.1.11 version
    Note that updated was suggested by Apple as part of setup of my new iPod Touch .
    Before it worked very well. I have already uninstalled and reinstalled iTunes 7.7.1.11.
    How I can return back ?
