Windows 10: Windows 11 too slow and showing 100 % disk usage

We had purchased some Vostro desktops in our office with Windows 10 64 Home, Core i3 9100 CPU 3.6 GHz, with 4 GB ram. Every time after booting up, they all have 100 percent disk usage and lag entire time. This happened even before installing the necessary software we needed. Now it automatically updated itself to windows 11. Also if I leave it running for some time, it goes to power save mode, and takes half an hour just to turn back on. I have tried running dell support assist and did everything it said. No use.specifications of the one of the six pc : Device name PC-FC Processor IntelR

100% disk usage

Hi,



My hard drive shows that it is at 100% and my laptop is very slow.



Can 100% disk usage increase the temperature of the hard disk?

 

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.

 

Windows Disk Usage is 100%

My computer has been extremely slow for a while. The Disk usage is always at 100%. (It shows up as 50% in the task manager list while 100% in the graph). Is there any solution for how to fix and speed this up? I have tried to turn off windows search index
and did the command "net.exe stop superfetch" but both did not have much of an effect. Any help on this issue would be greatly appreciated!
