As the OS has developed throughout the years, the quantity of normal mistakes has lessened, yet lamentably, some new ones have begun appearing. One certain mistake that we see on Windows 10, and that started with Windows 8 and 8.1, is the 100% Disk Usage Error. Adequately, what this does is scale your hard plate use to full, bringing about everything backing off to a creep and an extremely disappointed end client. Fortunately, there’s a fix for that, and in this post, we’ll talk about how you can alter the 100% Disk Usage blunder on Windows 10 and underneath.

Note: For the reason for this article, we’ll be particularly talking about Windows 10, in spite of the fact that the arrangements can apply to past variants of Windows too.

What causes the 100% Disk Usage Error

While there can be an assortment of purposes for it, by and large, this blunder is brought about by a few Windows administrations like Superfetch, Prefetch, BITS and Windows Search. While these components are the typical suspects, they’re not the sole ones; there can be an assortment of others, including malware, Flash and even a truly old and moderate hard drive.

Determining if you have the 100% Disk Usage Error

Confirming that you really are confronting this blunder is simple yet vital, in light of the fact that you would prefer not to circumvent rolling out improvements to your PC in vain.

While the gradualness of your machine will be a genuinely decent pointer (alongside an always on hard plate light), you can check the issue by pulling up the Task Manager in Windows 10 (simply hit Start and begin writing Task Manager, or press CTRL + Shift + Esc). In the Processes tab, the Disk segment will indicate 100% if the blunder exists; if not, you’ll see something like the screenshot underneath.


Fixing the 100% Disk Usage Error

Let’s suppose that your machine is suffering from this issue or problem then you would have to follow the below procedure:

1. Do a virus scan of your Windows 10 computer

This may appear like a general, judgment skills exhortation, yet it’s pivotal that you play out this activity as your first cure for this situation. Numerous a times a malware contamination can be the guilty party and you can do whatever else you need, it won’t alter the issue. Better to make sure in advance for this situation. You can utilize any great antivirus programming for this reason.

2. Disable Windows 10 Superfetch service

Superfetch is one of those Windows benefits that will dependably have the capability of conveying an ambivalent client experience. The reason behind Superfetch is that Windows will gain from your utilization propensities and “conjecture” which applications/administrations you’re well on the way to use next. In light of this forecast, the OS will reserve those applications and projects to the RAM, so they’ll stack quicker. Presently, in principle, that is an incredible idea, however unless you’re a robot that is modified to take after a specific schedule, Superfetch’s forecasts will undoubtedly miss every once in a while. What’s more, in light of the fact that the administration is caught up with pulling each one of those anticipated application documents and information from your hard plate, you get the 100% Disk Usage mistake.

Incapacitating Superfetch is much the same as debilitating some other Windows administration. In Windows 10’s inquiry, sort Services and open the Services discourse. Inside here, discover the Superfetch administration, and right-snap to get to Properties. Here, Stop the administration and in Startup sort, ensure it says Disabled. Hit OK and restart your Windows 10 PC for good measure.


3. Disable Background Intelligent Transfer Service (BITS)

BITS is yet another Windows 10 administration that should be useful yet can end up being an incredible inverse. The thought behind BITS is that when your PC is sitting inert, the data transfer capacity can be utilized for Windows Update, Windows Defender and so forth. While it for the most part works fine and dandy on more up to date machines, more seasoned equipment can really endure while BITS tries to disentangle when the PC is really sit out of gear.

Incapacitating BITS will be much the same as crippling the Superfetch administration, with the exception of that for this situation, you won’t handicap the startup out and out; rather, you’ll choose Manual.


4. Disable Windows Search

This is one of those “arrangements” that I’d by and large not suggest unless totally important. For a long while now, Windows has had an extremely vigorous pursuit work that records everything on your machine, making it simpler to discover documents and all other substance. While the component is all extraordinary, one rather persevering bug has been the “inquiry circle”, where a framework running Windows will interminably re-record documents and envelopes again and again. One brisk approach to recognize in the event that this is the reason for 100% Disk Usage is low CPU and Memory use in Task Manager close by 100% Disk Usage.


The drill is again the same here: discover Windows Search in Services, right-click for Properties and Stop the administration while debilitating the startup. On the off chance that this was the guilty party, you’ll see a quick effect.

5. Disable Windows 10 Prefetch

Windows 10 additionally packages a slick component to supplement Superfetch: Prefetch. While Superfetch stores information to RAM in light of shrewd speculating, Prefetch works when you dispatch those applications. Basically, Prefetch records data on documents that are utilized by any given application, and afterward pulls those records to RAM to enhance application stacking times.

Since it’s again savvy speculating by the OS here, there is a probability that the Prefetcher will miss. What’s more, it does. What’s more, when it does, debilitating it remains your coherent decision. Be that as it may, Prefetch isn’t your standard Windows benefit and tweaking it required rolling out improvements to Windows Registry, which is the reason we suggest this if all else fails arrangement as it were.

To open the Registry Editor, sort regedit in Windows 10 seek bar and hit Enter. In the envelope tree, explore to the accompanying area.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters


In the right side sheet, you’ll see a passage for EnablePrefetcher. Double tap it and change the DWORD esteem from 3 (default) to 0 to totally handicap the administration. You may likewise put in 1 as the DWORD esteem, which will keep Prefetcher in part empowered however debilitated for boot documents.


If you don’t mind take note of that you’ll have to restart your PC for every one of these progressions to produce results.

6. Run CheckDisk

CheckDisk is one of the most seasoned charge line devices at the transfer of Windows clients, and one that is generally useful. This will prove to be useful if there’s an issue with the physical hard drive, the envelope tree or anything of that nature with your Windows establishment. The best approach towards running CheckDisk is to do as such when your framework reboots, so you’ll have to really plan for that. Fortunately, that is genuinely simple.

Dispatch a hoisted order brief (sort cmd in Windows 10 look bar, right-click and select “Keep running As Administrator”) and run the accompanying summon:

chkdsk /f’ /r C:

where C: will be supplanted by whatever drive letter you’ve appointed to your Windows establishment. You’ll see a message inside charge provoke that will request that you affirm whether you’d like to run CheckDisk on next framework reboot. Recognize with a Y, and restart your PC. CheckDisk may take some an opportunity to complete, yet it can be exceptionally helpful for 100% Disk Usage blunder as well as some different issues also.

7. Disable Windows Tips

This one didn’t sound good to us, however many individuals have reported this did the trap for them. Windows 10 offers tips about the working framework now and again, and crippling those appears to have alleviated the 100% Disk Usage mistake for an assortment of individuals. We take note of this here in light of the fact that you won’t lose much in debilitating those tips, and it’s quite simple to do. Simply go to Settings, then to System and after that Notification and Actions. Incapacitate “Show me tips about Windows” in this rundown, and voila!
