18 Ways to Resolve a 100% Disk Usage on Windows 10


If you consistently find a very Large disk, use something that Isn’t Quite Perfect.

I wrote about upgrading Windows 10 freezing difficulties. In this article, I will be speaking about troubleshooting a second reasonably common problem, which can be disk utilization revealing 100% all the time. I have discovered this ailment is incredibly actual on notebooks.

Ordinarily, the disk utilization will go around or near 100 percent for a couple of seconds or perhaps for a few moments. Still, it should settle down into something more realistic (generally under 10 percent ). If you regularly observe a quite large disk utilization, it means there’s something else happening that is not quite perfect.

To begin, you can examine your disk usage by opening the Task Manager from Windows 10. It is possible to either right-click to the Start button and then choose Task Manager, or you could press CTRL + SHIFT + ESC. If you find a little collection of programs, click More details in the base.

On the principal Processes tab, you will see a fast summary of this CPU, Memory, Disk, and Network usage. Unless I am doing something about the computer, the disc use is generally right approximately 0. In a bad situation, you will see something similar to below where disk utilization is 100% or close to it.

Sometimes, you may see only one procedure that’s the reason for the high disk utilization; however, in other cases, the system that’s the reason for the spike can alter.

Do Not Try These Solutions

On the internet, I stumbled across many options that did not settle well with me since they could cause more problems in the future. Stay Away from doing anything listed under:

Disabling the BITS support: It is required by Windows to the PC to be upgraded, and it will not aid in disabling it.

Disabling Windows Lookup or Superfetch: Again, these are heart Windows solutions, and you shouldn’t disable these.

Ordered Page File: Now you need to leave it that Windows handles the webpage file. Do not attempt customized values.

Disabling Windows Defender: Except for Method 6, do not disable Defender.

Troubleshoot 100% Disc Utilization in Windows 10

Method 1 — Update Firmware for SSDs

In case you experience an SSD installed onto your device and are using the disc usage issue, it is probably an issue with the firmware. SSDs are quickly, and if you don’t have some application that’s accessing the disc all of the time, it actually must never be at 100 percent for over a couple of seconds.

Listed below are a couple of links to the SSD firmware upgrades for a number of the powerful brands: Vital, Samsung, Kingston, Intel, OWC.

Method 2 — Perform a Clean Boot

In case you’ve not completed a clean boot, then now’s the opportunity to understand. A fresh boot essentially heaps Windows together using all the most recent drivers and startup apps. A new boot can allow you to figure out if the matter has been due to Windows itself by a third-party application installed on Windows.

Microsoft has a fantastic article about the best way best to do a clean boot. I suggest trying it since it usually fixes lots of different issues also. It is somewhat time-consuming but completely worth the attempt. Set aside a couple of hours on the weekend to have it done.

If you realize that everything loads fine on a fresh boot, then gradually enable each startup application by one till you decide which app is causing the slowdown. You may then disable it or disable it. For starters, always begin by disabling any third-party antivirus/anti-malware application as these apps may incline to get into the disc all of the time.

In online forums, I have heard many individuals whine that Skype has been the origin of the disk utilization surge. So try entering Skype and see whether this works.

Method 3 — Update Memory (RAM)

One more thing that you would like to test is to observe just how much RAM you have installed onto your device. Since Windows 10 may run on old devices, I have seen plenty of individuals put it on older desktops and notebooks. That is nice, but you have to be sure that the machine has a nice RAM amount, meaning nothing less than 4 GB.

You might even start Task Manager and click Performance and after that click Memory.

I’ve 16 GB of memory, and approximately 6 GB is currently in use because you can see. This means if you have 4 GB of RAM in your pc, all of the memory will be emptied. Everything that can not be inserted into memory is paged into the hard disk drive. So essentially Windows can use your hard disk as a temporary memory apparatus.

In case you’ve got a great deal of information that needs to be written to disc, it will make your disk utilization spike along with your personal computer to slow down. If you observe that the point in this chart is near the very best, and this means you probably ought to update the RAM on your computer.

Method 4 — Use High-Performance Power Plan

With a few computers, the hard drives are innovative and will attempt to power down or alter RPM to conserve electricity. One example is that the green/blue Western Digital hard drives. It appears to be a fantastic feature. However, I do not believe it works all of them nicely in training.

To avert this issue, visit Power Options and then choose the High-Performance electricity program. Additionally, click Change plan settings and expand Turn off hard disk afterward which places the minutes.

This will ensure that the hard disk doesn’t power down or enter the low power condition, leading to the disk utilization issue.

Method 5 — Customize MSI Mode

This remedy is much vaguer and probably will not help many folks, but it is well worth mentioning because Microsoft has stated that this can be a problem in Windows 10. Fundamentally, it’s got something to do with AHCI, which can be specialized jargon that you do not have to understand.

Disk Utilization will show 100 percent whenever you have this matter, but if you type the column, then there is no specific application or procedure that’s displaying high disk utilization. It’s possible to read this Microsoft KB article below and try the repair.

Method 6 — Customize Windows Defender using 3rd Party AV.

By default, Windows Defender must disable itself if you’ve got third-party antivirus installed in your system. Nonetheless, on occasion, this doesn’t occur, and running just two antivirus applications at precisely the identical time may result in excessive disk usages along with a lot of different issues.

To assess if Windows Defender is disabled or not, then click Start, then Settings, then Update & Security after which Windows Defender. Ensure Real-Time security and Cloud-based Security are switched off.

It would help if you ONLY did this when you’ve got third-party antivirus installed in your system.

Method 7 — Hide Windows Notifications

This solution was widely distributed on the world wide web, but I am unsure whether it works or not. I feel it will work for specific variants of Windows 10. Anyhow, it does not hurt to disable it, so that is why I will mention it.

Essentially, you disable additional Windows notifications which are essentially ads. Proceed to Settings, then click System, Then Notifications and Tasks. Just switch off the Access ideas, tips, and hints since you use Windows.

It is well worth noting that your typical notifications will do the job just fine, you won’t observe any unworthy ones out of Microsoft.

Method 8 — Assess Hard Disk for Errors

If nothing over is functioning, then you may have an issue with your hard disk. There are many approaches to confirm your hard disk’s health, which I have written about earlier.

In several cases, repairing mistakes on the drive fixed the issue. In other cases, replacing the driveway was essential.

Hopefully, among the solutions above will do the job for you. 1 final resort choice is to execute a fresh install of Windows 10, which will repair the issue for anybody who appears to get malware installed in their programs and perhaps does not understand it. In case you have any queries, don’t hesitate to comment. Enjoy!

Method 9 — Slow Performance? Run Disk Verify

This performance problem is the most evident when utilizing Windows Search to locate a document or application. Whatever else needs that drive to do a little bit of work (maybe copying and pasting some set of documents ).

Flash is still one of the most vulnerable elements of contemporary computing and ought to be disabled. Adobe intends to kill its own multimedia plugin 2020, so there is very little reason to continue using it.

Flash also appears to be among the most frequent offenders for your 100% hard disk utilization in Windows 10 when utilizing the Google Chrome browser.

Open Menu> Preferences > Privacy and safety and click on the section marked Website Settings. Here, locate Flash and then place the toggle on Block websites from conducting Flash, then click.
