    Laptop updated to 1809 -- CPU pegged at 70-100% with nothing open

    So I've been having problems with this laptop since I upgraded. Not sure how I haven't noticed until now, but the CPU is constantly at or near 100%. Programs open slowly, wifi transfer speed (to another computer) is super slow, and it used to be quite fast.

    Opening resource monitor I can see that "SupportAssistAgent.exe" (which is a service) is using a lot of CPU. Damn Dell bloatware. I'm going to try and uninstall this.

    In the meantime, does anyone have any suggestions?

    Do you still have the option to return to 1803. If so I would use it.

    If not, and I'm not sure you are aware, task manager reports incorrectly in 1809. It is a know problem.

    Would suggest you check out sysinternals for a more accurate tool - Process Explorer.

    Since you've removed your bloatware what is the next highest usage task. Windows will re-index your machine so if you have a lot of data this is going to take some time.

    Have you run sfc /scannow against your system. If not please do so.

    Could you also check please and see if you might have a repeating Windows Update failure.

    Did you create boot media to do this upgrade? I ask as you could do a repair install. As you can't get 1809 from MS you need your own copy.

    Honestly my best recommendation is to revert to 1803. Lets see what sfc reports.

    Please provide
    a. appropriate screenshots of your task manager and resource monitor (part of task manager) - organised high to low by clicking appropriate column heading.

    To post a screenshot please use the Insert Image icon above your post. Thanks.
    b. details of your system disk

    Please compare performance after a clean boot.
    If unsure what that is, please search (Google) for

    Hi guys - thanks for the prompt replies.

    Surprisingly the issue has gone away for now... I found Support Assist to be still installed on the computer (I tried removing it a couple weeks ago) so I uninstalled it again... and there was another item called Support Assist which I uninstalled as well.

    I'm going to monitor performance and check if everything is working okay tomorrow - it's late now, so I'll report back requested details if I see things are still not working properly.

    Appreciate the help!

    Same issue here, task manager is falsely showing high CPU usage (over 80%) with nothing open. Yes, I have the "buggy" 1809 update.

    Thanks everyone - performance is much better. Support Assist seems to have been the problem - Task Manager does seem to report random CPU spikes however Process Explorer is much better - great recommendation.

    I think I'll keep 1809 as the laptop is quite unimportant and I'm sure future updates will fix any of the bugginess going on - right now it isn't affecting me.

    Thanks again for the help!

    Which company is the support assist....please post a URL or link.
    The computer displayed in the "My Computer" section was a desktop with Asrock.
    Was this a problem with a notebook not listed in the "My Computer" section?
