Simply Update Windows

Just like restarting your computer, you would be most likely surprised at how effective updating Windows fixes issues. We’ve fixed at least once Windows 10 computer that has 100% disk usage issue by simply updating the most recent Windows updates.

In order to see if your operating system is updated, just open up the Control Panel and head to System and Security then just click on Windows Update.

Now, in Windows 10, just open the Settings app or Start menu then cog icon then press on Update & security.

You will see an Install now or Check now button if there are updates available.

Utilize the Right Storage Driver

Now, if you can’t find any processes that are using plenty of disk resources, then it is probably that your PC is utilizing the wrong storage driver. You see, Windows is well conscious of the issue and this is actually the official solution to the 100% disk utilization issue.

In particular, it is a firmware bug in certain SSDs that causes Windows OS to think that it has not completed a task and resets the computer repeatedly. The best remedy to this is to disable the MSI mode. However, it is only applicable if you are running the inbox AHCI driver. For elaborated steps, you can check this out.

Nonetheless, of all the Windows computers and laptops that we have seen with 100% disk usage, none have actually suffered from such issue.

Use Task Manager

In task manager you can see which process or program is disrupting your disk. A fast approach to launch task manager is by pressing Ctrl then Shift then Esc all at the same time. Just press the More details arrow if Task manager is not showing the full interface. After that, click on the Disk column header in order to organize the list so it is ordered by Disk Usage with the highest one placed at the top.

This can only be your need to determine which program is disrupting your disk. However, more usually than not, it will be a Windows service instead of a program that is causing the issue.

Now, if it’s software or a program, just right-click on it and select End Task. This should halt the program from operating and you must see disk usage drop right down.

Of course, this is not a solution if you are using the app in place, thus it is worth searching first to determine why the Windows service or that particular program is constantly thrashing out your hard drive.

You could even find no evidence of a high disk load by any process. If this is the case, then proceed on the next approach below.

Restarting Your PC

Restarting your PC is the first fix you should try just like with any Windows issues out there. For sure, it sounds a little bit simple. However, it can usually solve problems that you might otherwise spend a lot of time troubleshooting.

Keep in mind that you won’t be able to use the Shut Down option if you are using Windows 10 OS since this saves the system state so it can start up much faster This implies that issues won’t go away.

Rather, you can utilize the Restart button which shuts down everything appropriately and performs a neat restart. And even after you restarted your PC and the issue still persists, just leave your PC alone for a couple of hour because it could be that weekly malware scan that is making it slow.

Of course, this shouldn’t cause any issue at all. However, if you’ve got an older PC with a pretty slow hard disk, then it is easily observable. So in this instance, you can simply upgrade your old disk to a much more efficient SSD. This method can fix a lot of issues in old computers with old and slow hard-drives.

Make sure to run a scan for viruses first before changing your drive using any antimalware software you’ve installed. The reason is, because malware could be the real issue.

Final Thoughts

Now, if all these approaches don’t fix your problems with 100% disk usage on your Windows 10 PC, you should probably take a peek into replacing your hard drive.

You can also attempt to disable any automatic defrag processes that are operating since they are probably causing you issues. All in all, your hard drive must never be at 100% usage because if it is, then there are probably more problems on your PC.

You should fix this issue right away or use a very slow-performing PC. If this article has helped you, please leave any feedback in the comment section down below.
