Windows 10: 100% constant disc usage - even when booting/turning off

Hi,Some time ago I noticed that my computer started to turn on really really slow up to 30 minutes at worst.Its working very slow due to constant 100% disc usage. I've run the sfc scannow, chkdsk, dism scans with no success. I also got some tools to see if there's any damage to my disc - also showing that all is working well.Yesterday I even reinstalled the Windows itself using the Media Creation Tool, thinking it may be the system causing the problem but although its working a bit faster it now boots in around 5-8 minutes its still working horribly.I did the antivirus scan with Windows De

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?

 

100% disc usage

I have been having problems with my Dell Optiplex 5260 for months now. I was running Windows 10 but have managed to upgrade to Windows 11 with some difficulty - its not easy with 100% disc usage - but still the problem persists.

When I start up the CPU and Memory are fine but the disc usage is 100%. I have done all the checks for damaged/failing hard disc but its fine. I have worked through all the suggestions in Kapilarya.com fix 100% disk usage in windows 11 and also lots of other suggestions on the internet but to no avail.

The one thing that has changed a bit since I started to work on this computer to try and resolve the problem is that sometimes, after about 20 mins or so the disc usage drops to normal levels for an idle computer with nothing running and then starts to fluctuate wildly from 0 to 100 and everything in between - see image attached.

Any thoughts and new ideas gratefully received. Its so annoying and has rendered the computer useless.

 

Disc usage 100% on boot up windows 10

BIG PROBLEM! all my windows 10 devises show 100% disc usage on boot up!

I thought out of interest I would check the usage in the i store models (which all run Windows 10) and they also show 100% disc usage! I have had 5 laptops all high spec all different brands! all of which have done the same and no matter who I ask, what
I try nothing fixed.

Anyone have any possible solutions?

Would a SSD for the OS help resolve this issue?

The 100% disc usage lasts for around 20 mins with no obvious culprit in task manager so what! On earth is going on! Is anyone else experiencing this! All of the store models are so surely someone has an answer PLEASE!
