    High disk usage and cpu

    Hi, sorry about my english first.
    I bought new lenovo ideapad Z400 touch 2 month ago with win8.
    last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
    When I have the Task Manager open, I notice the disk usage climbing to 50, 75, 100 also the CPU , even though there's scarcely any disk activity going on, the laptop's fan is working harder and very noisy , my processor's speed and heat are jumping high without any progrems on.
    I tried almost anything, cheacked for viruses, disabled unnecessary startup progrems, clean boot, but it still the same.
    please help.

    Sometimes TrustedInstaller/Windows Modules Installer Worker goes on a cleanup/compression binge, where you'll notice TIWorker.exe working the CPU in the background. Personally I'd just let it run for a few hours (maybe whilst you're doing something else), where it should complete doing what it's doing and the CPU will return to normal.

    If you're feeling paranoid, maybe go to the 'Details' tab and check the properties for the process to make sure it is actually the legitimate Windows Process that's running and not a fake one using the same name.
