Windows 10: Why does my disk say it has 100% usage

My disk says it has 100% usage even though nothing is really being used. Randomly it'll go down and go from 80 to 70 and then sometimes it'll go down to like 30%, but anytime I try and play anything it spikes up to 100 and stays there after I even turn off the game

100% disk usage

Original Post: Redirecting

I have been having 100% disk usage for quite a bit now, I had a post about it a while ago and did a clean boot as someone had suggested. The problem was fixed for a bit but when I got on the other day it was reverted back to 100% disk usage. Replied to my post saying what happened and after a few days no one had responded with instructions. Nothing else has happened since then. Help.

 

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.
