100% Disk Usage, tried some methods found online.

Hi! Basically my laptop running on windows 10 is experiencing 100% disk usage at idle.
I have tried to use resource monitor to find the culprit. Heres what it shows:


Basically it shows that System is causing high disk usage. However at times, resource monitor also showed that svchost.exe is causing high disk usage.

I have tried stopping the DiagTrack service in the services.msc, it did improve the performance of the computer as the computer was less laggy. However, disk usage still remains high at 100% with occasional decrease to 90%.

Does anyone have any ideas on how to solve this problem? I have searched on forums online for solutions to this problem however none of it seems to be working.

Thanks for ya help!

Hi please work thru the steps here, checking your disk is good, running chkdsk, performing the performance test, etc. and posting the result.

As I've commented there, the transfer rate is too low for that to correctly be a high %ge of disk usage.

The links right at the end after you've dealt with basics look interesting.

I note searchui.exe (that's Cortana, not Windows indexing search) is using a lot of resources.
Searchindexer.exe is part of Windows indexing, however. If it is having difficulty accessing your disk, that might account for that.

History: how long ago was your disk performance ok?
Have you recently upgraded to Win 10 or a new build of Win 10?

What sort of disk is it? SSD? HDD? SSHD?

Hi! I've realised that windows update was downloading several updates during the time when my post was created, which may have caused the high disk usage. Right now, windows updates have stopped downloading updates and my disk usage has gone down from 100%. (Using the method of stopping DiagTrack in services.msc)

Sorry for the trouble! Thanks for your help still and the links at the end are pretty useful!

*I will definitely take note on posting a screenshot on the forums in the future.

Hmm.. Just found out that at times the disk usage does spike up to 100% at 10mb/s or less when loading webpages or installing new software. Any ideas on what can I do?

Thanks!

Have you done that (my post#2)? There are some interesting links I posted at the end.
Please post screenshots as you work through it. Variety of possible reasons.

Hi! I will do a disk check and get back to you. I've downloaded Hard Disk Sentinel, but it didnt show any errors.

Thanks!
Here are links to some pictures of Hard Disk Sentinel which may be useful:

Hi! Done a disk check, here's the result:


I forgot the first step in #2 of that thread, will do so now and post back my results.
Thanks!
