Windows 10: System ntoskrnl.exe keep fluctuating between 0 to 100% disk usage

My new Asus Zen AiO running Windows 10 has been on 100% disk usage constantly to the point that it is impossible to use the PC at all.


I have googled and run all these, which only improved slightly:


Settings > Notifications & actions and turning everything off


Virtual Memory under Advanced System Settings, set to zero


Disable windows update

Disable Print spooler


delete temp files C:\windows\temp


Executed these under a batch file:

net.exe stop sysmain Stop superfetch

net.exe stop "Windows search"
chkdsk.exe /f /r
sfc /scannow
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth



reinstall Chrome

reinstall Windows 10 and update to the latest 20H2 with latest patches.


Finally, I use msconfig and disable every service I think is not critical. Now system ntoskrnl.exe only hit 100% disk usage once in a while, but it's still quite frustrating that Windows keep pausing once in a while because of this.


What actually is the kernel trying to do???

Upgraded to Windows 10 - Disk 0 Usage 100

I agree. This entire thread has appeared unproductive as this issue continues. The one point perhaps that has not been discussed appears to be that even though the disk 0 usage is at 100% the processes running never add up to 100percent. for example at 24%
usage there are 10 processes listed as using 0.1 mb/sec which totals 1MB /sec. from that one could assume that at 100% the processes may total 4MB/sec but I routinely see the system process spike upwards of 25Mb/sec and after any usage climbs over 7mb/sec
the disk 0 reads at 100%. also the running processes are never the same. there is no one process which creates the issue.

A better solution would be for Microsoft to explain the point and purpose of the disk usage, and how it is reported. it is reported at the top as a percentage and in the row as a transfer speed. (mb/s).

The question is what is up with that specifically, how do I determine the max transfer speed of disc 0, and at what point will system performance slow to an unacceptable user level? when it does what are the steps to take to identify and resolve the issue?

 

DISK USAGE (first 100%, then 0-20%)

I will check the link you provided with WIKI about this app (actually I already checked it.. but will do again).

I want to add right settings... any chance that you help me with setting up WPRUI.exe so that the results can show us what causing my problems?

I would like to start this app immediately after I boot up... and let it run for 15 minutes

Generally:

• 0-5 mins: 100% disk usage (according to task manager ACTIVE TIME)
• after that: 0-20% disk usage (according to task manager ACTIVE TIME)

It would be helpful if you tell me which options to turn on in this app.. .considering my problem is the DISK

 

Disk Usage 100%

Hey

Thank you for the reply,but your suggestion proved no use to me still the disk usage remains 100 percent and my system lags in performance.
