  1. Disk usage at 100% in task manager while connected to wi-fi


    My laptop runs extremely slow. When I open the task manager, the "Disk" column shows 100%. This only happens when I'm connected to Wi-Fi. If I'm disconnected, Disk usage fluctuates between 0%-3%The top items in the "Name" column fluctuate between "System," "Antimalware Service Executable," "Service Host: SysMain," "Host Process for Windows Tasks," "wsappx" "Microsoft Edge Installer"Most of the time they are running below 1.0 MB/s, but sometimes one of them will shoot up to 7 MB/s + but the Disk usage will be at 100% regardless. This has been happening for at least 4 years. Things I have recent

  2. Task manager showing disk usage 100%

    100% disk usage can have many causes.

    What are the top 5 processes listed in the task manager using the disk?

    Windows 10 - 100% Disk Usage in Device Manager

    A concerning issue I am currently facing with my PC is the disk usage, where my PC is best described as lethargic during start up, and less commonly but evidently unresponsive afterwards. Upon checking the task manager, it informs me the disk usage is at
    100% - so obviously something is draining this feature. What isn't so obvious is what is causing this, despite the task manager alerting me to the numerous software which is causing it. I end the task for the notable issues, and the 100% warning still
    remains. This has happened to me over a year ago, and I did a restore and wiped everything. This fixed the issue for me temporarily, and the 100% disk usage came back to me within a few weeks. At the moment I
    have 1.2TB of the 1.81TB SSHD space free, and my computer specs are below (I don't know if this will be useful).

    I have searched online and I have found a guide which I have linked
    here
    . I have completed each and every step that the guide asks me, and I keep running into this 100% disk usage. For a run down, I have:

    • Disabled Windows Search
    • Disabled Super Fetch
    • Performed a Disk Check (Took 8 hours, did nothing!)
    • Reset Virtual Memory
    • Changed the settings in Google and Skype
    • Fix the "StorAHCI.sys driver"
    • Updated device drivers

    At this moment, I am stumped into what to try next. I am reluctant to restore everything off my machine again, as the issue came back to me within a few weeks. Any tips and suggestions would be greatly appreciated!

    Many thanks,

    Chester
