  3. How to solve 100 % disk usage in windows 10 after fall update?

    Hi Manikanteswara,

    Usually, a virus could be the main cause of 100% disk usage. The first step in rectifying the problem is to check your disk usages. You need to open the Task Manager and take a look at your disk usages to identify the programs or applications that are causing
    your hard disk 100% usage. Here's how:

    • Type task manager in the Windows search bar and select the best match.
    • In the Processes tab, look at the disk process to see what is causing your hard disk 100% usage.

    Kindly send a screenshot, so I can take a closer look.

    Hoping to hear from you soon.

    100% disk usage and memory usage

    Hi,

    100% disk usage and memory usage can be caused by a software corruption, running application running on the background and malware or virus infection.

    For us to properly isolate the issue and provide an appropriate resolution, kindly answer the questions below:

    • Did the issue happen after installing the Fall Creators?
    • Did you receive any error messages?
    • Can you send us the screenshot of the Task Manager showing the 100% disk usage and memory usage?
    • What troubleshooting steps have you done so far?

    For isolation purposes, please perform a clean boot to see if the same issue will occur. Refer to this
    article for more information on how to perform a clean boot
    in Windows.

    Looking forward to your response.
