    System Idle Process and TaskHost.exe hogging CPU performance


    Hi All,

    Recently i have been having high CPU usage (100%) due to the following :

    - System Idle Process (Consumes about 35%)
    - TaskHost.exe (Consumes about 20%)

    I personally do not better know how to check what's causing them and even more so how to fix it. Maybe some one can direct me as to how to view the problem so that I can post it on to better seek your assistance.

    The 35% system idle process is an indicator of how much is NOT being used. Higher is better. It's 99% right now on my PC.

    Use Task Manager to track down what's using the remaining 65%.

    Taskhost.exe is using 0% right now on my PC.

    Check the performance tab to see how much RAM you are using.

    Check the processes tab of Task Manager. Do you have 50 running or 100? Which are using the most CPU cycles?

    Run MSCONFIG and look at the services tab. How many non-Microsoft services are running?

    Post screen shots of Task Manager if possible.

    Something is using the other 45%. What are those. What is your CPU ?

    Hi,

    I have taken screenshot of those that you recommended.

    The host process for windows task really consumes alot. The remaining ones are largely chrome.

I recently noticed that one of my internet computer's (Duo Core) CPU was red-lining much of the time and responses obviously became much slower. The Task Mgr "Processes" revealed that a process named "searchsetting.exe" was using over 50% of the CPU. When I "end the process", the CPU usage...
