    Taskhostw.exe CPU usage 100% slowing everything down


    I hope someone is able to help as I have spent the entire weekend driving myself insane trying to fix this. My laptop started running slow and freezing. I use it for writing and emails, no gaming or anything exciting. It turns out my CPU usage is at 100% due to taskhostw.exe.I have tried everything suggested online. The SFC scan, system restore etc. I tried seeing if I could close things in task manager but there are 90 processes running and I have no idea what is was. None seem to be using CPU according to that though. Any advice is welcome. Thanks!

    :)

    cpu usage at 100%

    CPU usage at 100% from start up for no apparently good reason. Service Host appears to be the problem but I cant narrow it down more than that at present.

    Any suggestions?

    I am using Windows 10 full release version 64 bit.

    cpu usage high internet slow windows 7

    Brevity can be a virtue but it can also be counter-productive.

    • Which application demands excessive CPU resources?
    • What would you like to ask?
