    What makes your cpu and disk % go really high?


    I've had high cpu and disk % all morning long, I literally just looked at my task manager again while typing this and their back to normal. How do I fix this so everything stays at a good level?

    When you first log in, windows delays some of the services and startup programs, and that's one of the reasons you see CPU and disk usage spike all morning long. Another is the scheduled maintenance and shadow copy service where it only resumes when the system is on idle.

    Can be anything. You have to check in task manager when it is high. Strange things can happen. Recently I had the print spooler running all the time although there was nothing in the print queue.

    My disk was staying between 80-87% and when I checked what was causing it there was only 2 things at the time and each thing was between 0.1-0.6mb.

    Sorry, forgot that you are in Windows 8.1. There you have to look into the Details tab.

    It shows you the process that uses a lot of CPU. Once you have that, post it here and we'll discuss.
