Windows 10: 100% disc usage while idle

My disc usage has been jumping up to 100% randomly but most of the time it's when I get up for a few minutes and come back. I left task manager open while I was away and when I came back, the disk usage was stalled at 100% with "system" being at the top of the list. This always fixes about 20 seconds after I start using the computer again which is odd to me. I've tried a couple of things I read online like disabling Superfetch and also deleting DiagTrack. After deleting DiagTrack, everything felt way faster but my disc usage still hops to 100% while idle and also sometimes while is use. I upgraded to Windows 10 a few months ago but just started having this problem a couple of weeks ago, or at least that's when I first noticed it. Is there anything else I can do to try and fix this problem? I have the option to update to Windows 2004 as well if that would help anything

Disc Usage at 100%

Hi Andre,

Thanks for getting back to me.

I started going through your list of suggestions.

I have switched off all background apps. I was horrified to see so many.

I then disabled windows update.

At that stage I thought I would check out disc usage on task manager.

Disc activity had gone down dramatically and in the performance tag activity was very low, it spiked from time to time if I did something on the PC but the speed on all activity was back to normal.

I thought I would leave things as they were and see if things stayed the same.

No problems at all until this afternoon I was trying to look at a file via windows explorer and got the message "not responding". A quick look at task manager and disc activity is 100% again. Everything slows down. I close down some screens and the desk
top turns black.

The only way I can get a display up again is "alt" + "tab". The task bar has disappeared. I decided to reboot but the only way I can do that is with the on'/off switch.

The PC reboots. I check that all the apps are still switched off and windows update is still disabled, Disc activity is still 100%.

As I type this disc activity has suddenly dropped. it keeps spiking to 100% but then reverts back to about 12%.

Is this normal or is there something else I should do.

Back to 100% now. How do I find out what is actually happening, what activity is the disc doing?

I am confused.

Any suggestions?

 

CPU usage 100% but system idle process says otherwise

Hello, So I was copying a large group of files (400 gigs) to an external drive, it was about 150 gigs in when the PC crashed ( i believe due to MSI usb speed up), i've since removed the MSI program but CPU usage stays at 100% from the moment the PC turns on, however system idle process shows it's using most everything which is good, and PC perfomance is normal and unlike if CPU usage was actually 100%, but I can't figure out how to fix this, any suggestions or tips would be so helpful, I've attached screen shots showing 100% usage but every program running doesn't add up to near that and system idle showing everything mostly idle. Thanks!!!!!
