10 Ways to Fix 100% Disk Usage in Windows 10
High disk usage can bog down your system.
- University of Maine
- The Ultimate Laptop Buying Guide
A slow-running computer often bogs because Windows commits significant system resources into disk read and write operations. When you open Task Manager and see 100% disk usage, stopping the process that's forcing that use brings Windows back to normal working order.
Many of the following fixes for 100% disk usage in Windows 10 are relevant to Windows 10, 8, 7, and Vista. However, some commands and system settings may vary.
Causes of High Disk Usage on Windows 10
There are several potential causes for high disk usage in Windows 10, but most come down to the same basic idea: Too many things are running for the computer to handle.
One common cause is swapping or paging. Swapping occurs when a computer runs out of physical memory (RAM) and needs more space to store information about the running processes and applications. It uses a file on the hard drive called swapfile.sys to hold it. As Windows works with that information, it constantly reads and writes to swapfile.sys, driving up disk usage.
You also might find that applications that search through or use many files at once access the hard drive at an alarming rate behind the scenes. Many applications can behave this way, including antivirus software and some utilities that are installed with Windows.
How to Fix High Disk Usage on Windows 10
Most of the time, the fixes for high disk usage come down to finding the process that uses the hard drive frequently and stopping it. Below are a few of the most common solutions.
Disable Windows telemetry . Windows 10 collects data about the way you use it in the background. It's been the topic of controversy for privacy reasons, and it's a common cause of high disk usage. Disabling the service responsible can help give the hard drive a rest.
Disable Windows search indexing . Windows keeps track of your files and where files are located on the drive, so you can easily search for the file you need. Sometimes, the process Windows uses to create an index of where those files are can slow down the drive. Disable search indexing to decrease stress on the drive.
Disable SuperFetch . The SuperFetch utility runs in the background on Windows, analyzing RAM usage to see which apps use the most. SuperFetch can use a lot of system resources, including writing to the drive frequently. Disable it to stop the process from running behind the scenes and writing to the drive.
Disable Windows Tips . As you use Windows, an integrated app running in the background offers notifications with advice about the operating system. While this is the least likely problem causing the disk usage utilization error, it is one more app running in the background that can cause problems. Turn off Windows Tips and see if it improves your system performance.
Give Skype write permissions. If you run Skype for Desktop on any Windows version before Windows 10, Skype could be causing the disk usage problem. If Skype doesn't have permission to write data to one of its subfolders in Program Files (x86), it continues to write and ramps up hard drive usage.
To change permissions, right-click Skype.exe in C:\Program Files (x86)\Skype\Phone\ , then go to the Security tab and select Edit . Next, choose All Application Packages , then select the Write check box under Allow . Finally, to close, select OK .
Disable prefetch in Chrome . A few features in Chrome speed up your browsing experience. One of those services is a prediction service in Chrome that analyzes what site you're likely to visit and preloads those pages in the background. However, this service puts an extra load on your computer and the hard drive.
In Firefox, disable prefetching by visiting about:config in the address bar and setting the network.prefetch-next value to false .
Fix the AHCI driver. Microsoft acknowledges a known bug with some Advanced Host Controller Interface PCI-Express models on Windows 10. If your computer is affected, you'll experience 100% disk usage problems. To fix it, do the following as described below.
First, check that your computer has the AHCI driver by opening the Device Manager and looking at the item IDE ATA/ATAPI . If you see SATA AHCI Controller , open it and select Properties . Under the Driver tab, choose Driver Details . Here, look for the driver storahci.sys . If you see it, then your PC could be susceptible to this known bug.
If you discovered that the storahci.sys driver file is on your system, change its value in the Registry Editor. Go to Details in Device Manager and choose the Device instance path from the drop-down menu. From here, copy the value listed and paste it into a text editor like Notepad.
Next, open Regedit and browse to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ . Expand the folder of the value you saved in a text editor. Inside this folder, open Device Parameters\Interrupt Management\MessageSignaledInterruptProperties , double-click MSISupported , and change its value to 0 .
Editing inside the registry opens the door to inadvertent, significant configuration errors. Changing the wrong values may destabilize your computer. Make a backup of the registry by clicking File > Export and saving the .reg backup file to a folder or external hard drive.
Add more RAM . If disk usage is high because your computer doesn't have enough physical memory (RAM), the best solution is to add more. RAM is one of the easiest upgrades on any PC, and it's relatively inexpensive. Plus, your computer will be able to multitask more efficiently as a result.
Disable automatic Windows Updates . Another common cause of high disk utilization sources from Windows Updates taking place at random times, automatically. Stop Windows from updating at random, and you'll stop the drive from maxing out.
If you disable automatic Windows Updates, run manual updates frequently. This process ensures you receive important security updates that keep your computer safe from viruses and malware.
Scan for malware . If all else fails, there's a chance your computer could have a virus or malware. The best thing to do at this point is to make sure you have good antivirus software and run a full system scan. A full scan can take a long time, but it finds and removes any malicious software running on the system and spiking the disk usage.

Fix 1: Disable SuperFetch
SuperFetch helps to decrease boot time and make must-load programs more efficiently. However, it has been identified as a potential cause of disk performance issues in Windows 8 and later versions of Windows, including Windows 10. Here’s how to stop this service:
1) On your keyboard, press Windows logo key , type command prompt , then select Run as administrator .
2) Click Yes at the User Account Control prompt.
3) The command prompt will once again display. Type in the following command:
4) Hit Enter on your keyboard.
5) If the command above isn’t valid, try the following one instead:
6) Wait for a few minutes to see if your computer starts performing better. Or check your computer’s disk usage: Type “task manager” in the Windows search bar and select Task Manager , then in the Processes tab, look at the % at the top of the Disk column. If it’s no longer 100%, you’ve fixed the problem!
If the 100% disk usage problem persists, try the next method, below.
Fix 2: Update your device drivers
If the steps above don’t resolve your 100% disk usage problem in Windows 10, it may be caused by a device driver.
You can automatically update all your device drivers to the latest correct version with Driver Easy .
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

4) Check your computer’s disk usage: Type “task manager” in the Windows search bar and select Task Manager , then in the Processes tab, look at the % at the top of the Disk column. If it’s no longer 100%, you’ve fixed the problem!
Fix 3: Check for corrupted system files
Corrupted or missing system files can also cause the 100% disk usage error. To see if this is the cause for you, run a system scan to detect broken system files with Reimage .
Reimage is a professional Windows repair tool that can scan your system’s overall status, diagnose your system configuration, identify faulty system files, and repair them automatically. It gives you entirely fresh system components with just one click, so you don’t have to reinstall Windows and all your programs, and you don’t lose any personal data or settings.

Restart your computer to see if you still get the 100% disk usage error. If you do, please try the next fix below.
Fix 4: Perform a disk check
1) On your keyboard, press Windows key and X at the same time, then choose Command Prompt (Admin) .
3) The command prompt will once again display. Type in the following command:
4) Hit Enter on your keyboard, then type Y to confirm that you’d like to perform the disk check the next time you restart your computer. Please make sure you have closed all of your applications first.
IMPORTANT: Disk check will start the next time you boot your PC and it might take some time to complete (could be a day for some). If, when you restart, you don’t have time to wait for the disk check to complete, you can skip it. You’ll need to reschedule it again, as described above, though.
5) Once you’ve completed the disk check, check your computer’s disk usage again: Type “task manager” in the Windows search bar and select Task Manager , then in the Processes tab, look at the % at the top of the Disk column. If it’s no longer 100%, you’ve fixed the problem!
Fix 5: Reset Virtual Memory
Virtual memory can be considered an extension of your computer’s physical memory. It’s a combination of RAM and a portion of your hard drive. When the RAM isn’t enough to perform a task, Windows will temporarily store files in virtual memory, then swap them back to RAM when required.
To reset virtual memory: 1) On your keyboard, press Windows key and Pause/ Break key at the same time. Then choose Advanced System Settings on the left panel.
2) Go to the Advanced tab, then click Settings .
3) Go to the Advanced tab again, and choose Change… in the Virtual memory section.
4) Ensure the Automatically manage paging file size for all drives checkbox is NOT ticked.
5) Select your windows drive (the hard drive or partition that has Windows installed on it – usually C: ) , and enter an Initial size and Maximum size for your virtual memory:
- Initial size – This value varies, depending on your computer. If you’re not sure what value to use, just enter whatever the number is in the Recommended category.
- Maximum size – Don’t set this value too high. It should be about 1.5 times the size of your physical RAM. e.g. A PC with 4 GB (4096 MB) of RAM should have no more than about 6,144 MB virtual memory (4096 MB x 1.5).
Once you’ve entered your virtual memory values, click Set , then click OK to continue.
6) Clear all your computer’s ‘temp’ files. On your keyboard, press Windows key and R at the same time, then in the Run form, type temp and hit Enter . This will invoke Windows Explorer with your Temp folder open, showing you all the temp files on your computer.
7) Select all the files in the Temp folder and delete them.
8) Check your computer’s disk usage: Type “task manager” in the Windows search bar and select Task Manager , then in the Processes tab, look at the % at the top of the Disk column. If it’s no longer 100%, you’ve fixed the problem!
Fix 6: Disable Antivirus Software temporarily
If you’ve installed antivirus or anti-malware programs such as Norton, Kaspersky, AVG, Avast Behavior Shield or Malwarebytes, you should temporarily turn them off or disable them to see if they’re causing your disk usage problem.
Please see your antivirus software’s documentation to learn how to disable it. You might also find these links useful:
- How to temporarily turn off Norton Antivirus program?
- How to stop AVG temporarily?
- How to disable Avast temporarily?
Note that Microsoft has its own default anti-malware, Windows Defender . It’s automatically enabled even if you also have other antivirus applications installed. Even if you disable your other antivirus programs, Windows Defender is always there for you during that certain time range. So, no need to worry too much about temporarily turning antivirus off.
Once you’ve disabled your antivirus , check your computer’s disk usage again: Type “task manager” in the Windows search bar and select Task Manager , then in the Processes tab, look at the % at the top of the Disk column. If it’s no longer 100%, you’ve found the problem, and you should contact the vendor of your antivirus software to see if they can provide some help.
Fix 7: Fix your StorAHCI.sys driver
Note : A million thanks to our warm-hearted reader Javier for the following solution.
The Windows 10 100% disk usage problem might also be caused by some Advanced Host Controller Interface PCI-Express (AHCI PCIe) models running with the inbox StorAHCI.sys driver due to a firmware bug.
Here’s how to determine if this is your problem and fix it:
1) Open Device Manager by pressing Windows logo key and X at the same time to choose Device Manager .
2) Expand the IDE ATA/ATAPI Controllers category, and double-click the AHCI controller .
3) Go to the Driver tab and click Driver Details . If you can see storahci.sys stored in a path of system32 folder, then you are running the inbox AHCI driver.
4) Close the Driver Details window and go to Details tab. From the drop-down menu, select Device Instance Path . Make note of the path, starting from VEN_ .
5) Type regedit in the search box of Start panel, then hit Enter on your keyboard to run Registry Editor. Then go to:
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Enum \ PCI \ < AHCI Controller > \ < Random Number > \ Device Parameters \ Interrupt Management \ MessageSignaledInterruptProperties
The < AHCI Controller > here refers to the name you see from step 2).
The < Random Number > differs on different machines.
6) Double click the MSISupported key and change the value to 0 .
7) Restart your computer after the change, then check your computer’s disk usage: Type “task manager” in the Windows search bar and select Task Manager , then in the Processes tab, look at the % at the top of the Disk column. If it’s no longer 100%, you’ve fixed the problem!
Fix 8: Switch to ChromeOS
Windows is a very old technology. Sure, Windows 10 is relatively new, but it’s still just the latest iteration of a decades-old operating system, designed for a bygone era (pre-internet).
Now that we have the internet, fast connection speeds, free cloud storage, and endless web apps (like Gmail, Google Docs, Slack, Facebook, Dropbox and Spotify), the entire Windows way of doing things – with locally installed programs and local file storage – is totally outdated.
Why is that a problem? Because when you’re constantly installing uncontrolled third-party programs, you’re constantly opening the door to viruses and other malware. (And Windows’ insecure permission system compounds this problem.)
Plus the way Windows manages installed software and hardware has always been a problem. If your computer shuts down unexpectedly, or a program installs, uninstalls or updates incorrectly, you can get ‘registry’ corruptions. That’s why Windows PCs always slow down and become unstable over time.
Also because everything’s installed and saved locally, it doesn’t take long before you run out of disk space, and your disk gets fragmented, which makes everything even slower and more unstable.
For most people, the simplest way to solve Windows problems is to ditch Windows altogether, and switch to a faster, more reliable, more secure, easier to use and cheaper operating system…
ChromeOS feels much like Windows, but instead of installing heaps of programs to email, chat, browse the internet, write documents, do school presentations, create spreadsheets, and whatever else you normally do on a computer, you use web apps. You don’t need to install anything at all.
That means you don’t have virus and malware problems, and your computer doesn’t slow down over time, or become unstable.
And that’s just the start of the benefits…

How to Fix 100% Disk Usage on Windows 10
From the simple to the drastic
It’s surprising when your disk usage suddenly hits 100% for no apparent reason. Luckily, there are a number of ways to fix this error on your Windows 10 PC.
Since the actual cause isn’t known most of the time, follow the methods below sequentially, and one of them should fix your issue.
Before you get started, you can try to narrow down the issue by going to Task Manager in Windows 10 and looking for the process or program that’s hogging your disk. You can right-click on the Start button and choose Task Manager or you can press Ctrl + Shift + Esc together to open it.
Click on the Processes tab and then click on the header for the Disk column to sort it. When performing methods 2 and 3 below, you can start with the process that’s using the highest percentage of the disk.
1. Restart Your PC
When you restart your PC, many temporary settings get reset. This is useful to fix various types of issues, and can possibly fix the 100% disk usage issue.
To reboot your PC, open the Start menu, select the power icon, and choose Restart .
2. Disable Startup Programs
If your PC shows 100% disk usage when you first log onto the computer, but then the usage settles down after a few minutes, your startup programs are probably the culprit. These programs launch when your PC boots and they eat up a lot of resources.
In this case, you should turn all these startup programs off and see if that improves your disk usage by following the steps listed below:
- Right click on the Start menu and click on the Task Manager .
- Click on More Details on the bottom left of the pop up window.
- Select the Startup tab. Right-click each program on the list and select Disable .
- Restart your PC and see if the issue is resolved
You can always re-enable any startup program after you complete this test. It’s also worth noting that disabling the startup of a program does not uninstall it. You can run the program any time, you just have to manually launch it.
3. Perform a Clean Boot of Your PC
When you clean boot your Windows 10 PC it only loads selected programs and services. This helps identify particular apps that may be causing the disk usage to reach 100%. Disable the identified apps to see if the issue gets fixed.
In Windows 10, use the built-in System Configuration app to perform a clean boot . We have a dedicated guide on how to do that, so check that out. It’s a bit of a time-consuming process, but it works really well for these types of situations.
4. Update Your PC
You should always install the latest Windows updates as soon as they become available because they install bug fixes to enhance performance and could fix your disk usage issue, too.
Follow these steps to update your Windows 10 PC:
- Open the Settings app by pressing Windows + I on the keyboard.
- Select Update & Security at the bottom.
- Select Windows Update on the left.
- Select the Check for updates button.
- Wait for Windows to find newer updates and install the available updates.
Reboot your PC to make sure the newly installed updates work properly.
5. Disable Scheduled Disk Defragmentation
If Windows 10 shows 100% disk usage only at specific times, scheduled disk defragmentation could be the cause. This is because the defragment task runs automatically at scheduled times and uses a lot of disk space.
Turn the scheduled disk defragmentation off and see if that fixes your problem.
You can always manually run a defragment task using the defrag utility.
- Open the Start menu and search for Defragment and Optimize Drives . Select the first result.
- Select the Change settings button on the Optimize Drives window.
- Deselect the Run on a schedule (recommended) box, and select OK at the bottom.
In the future, if you need to defrag your disks, select the Optimize button in the above utility. This runs a manual defragmentation task.
6. Delete Temporary Files
Many Windows 10 features and installed apps create temporary files that don’t need to be preserved.You can clear your temporary files using the following steps to see if that fixes the 100% disk usage problem.
- Press Windows + R on the keyboard to open the Run box.
- Type %temp% in Run and click OK to open the temporary folder.
- Press Ctrl + A to select all files in the folder.
- Right-click any one file and select Delete . This deletes all your temporary files.
- Go to your desktop, right-click the Recycle Bin icon, and select Empty Recycle Bin .
- Restart your PC.
This should, hopefully, fix the problem.
7. Repair Corrupt Files
A corrupt system file can cause the disk usage to hit 100%. However, Windows 10 has a built-in tool to fix these files. You can follow the steps below to simply run the command to enable this tool.
- Access the Start menu, search for Command Prompt , and select Run as administrator on the right.
- Select Yes in the User Account Control prompt.
- Type sfc /scannow in the Command Prompt window, and press Enter :
- Windows shows the live fix progress on your screen.
Wait for the process to finish and if this doesn’t take care of the issue move on to the steps below.
8. Run a Security Scan
One possible reason your PC shows 100% disk usage is that your PC may be infected with a virus or malware . You can run Windows 10’s built-in antivirus program to find and remove any malicious files from your PC by following the steps below.
- Open the Start menu, search for Windows Security , and select the first result.
- Select Virus & threat protection .
- Next select Scan options .
- Choose the Full scan option, and select Scan now at the bottom.
Wait for the antivirus program to find and remove viruses and malware from your computer, which will hopefully resolve the issue.
9. Modify Energy Options
Some users report that changing the energy plan can fix the 100% disk usage issue in Windows 10.
- Open the Start menu, search for Control Panel , and select the first result.
- Change the View by setting in the top right corner to Category .
- Select System and Security .
- Select Power Options on the next screen.
- Identify your currently selected power plan and click on the Change plan settings next to it.
- Select Change advanced power settings .
7. Click the dropdown menu at the top and cycle through the other options with a PC reboot between each selection. For example, if this menu has Balanced as the current selection, change it to one of the other available options. Select Apply or OK at the bottom to save your changes. Reboot the PC.
8. If this does not fix the problem, repeat Step 7 with the other available options.
You can always go back and select the original energy plan if this does not fix the problem and try the steps mentioned below next.
10. Change Google Chrome Options
If you use Google Chrome, there are options in this browser that can cause your disk usage to reach 100% . Turn these options off and see if this resolves your problem.
- Launch Google Chrome on your PC.
- Select the three vertical dots menu at the top-right corner.
- Select Settings .
- Expand the Advanced menu on the left, and choose System from the expanded menu.
- Turn off Continue running background apps when Google Chrome is closed on the right.
- Select Privacy and security in the left sidebar, and choose Cookies and other site data on the right.
- Scroll down and disable Preload pages for faster browsing and searching .
You can always re-enable the options if this does not fix the issue and move on to the next step mentioned below.
11. Turn Off Your Antivirus Program
If you’re running a third-party antivirus program, you want to make sure it’s not causing this issue by temporarily disabling it.
Also, Windows 10 comes loaded with an antivirus called Microsoft Defender Antivirus that does a pretty great job of catching most malware and spyware, thus negating the need for a third-party program in the first place.
12. Clean Install Windows 10
If none of the above methods work, your last resort is to clean install Windows 10 on your computer. This removes everything that your PC currently has, and installs a fresh version of the Windows 10 operating system.
Make sure you backup your important files before you do that, or you’ll end-up losing your files.

Fixed: 100% Disk Usage on Windows 10 Task Manager (Update)
To fix 100% disk usage on Windows 10 Task Manager, you can refer to 9 effective and easy methods in this post and try one or more.
Disk Usage at 100% on Windows 10/11 Task Manager
Sometimes, you may meet a problem with lag and everything seems to start up slow and take forever to load, especially Windows PowerShell and starting commands in it. The disk usage will spike from 0-1% all the way from 50-100%+ on 0.1 mbs of use from various programs.
This will noticeably come up with Windows PowerShell and executing commands, starting up Windows in general, or just different programs and applications wont loads right away. Here is the case:
“When I load into my Windows 10/11 computer, I can move the mouse but nothing else responsive. I tried to open the Task Manager, but when I click the Start menu, it took about a minute. What shocked me is that the disk usage is at 100% utilization in Windows Task Manager. Meanwhile, the CPU is at 17%, and memory is at 60%.
So why would the disk usage at 100% in Windows 10/11? After few restarts sometimes it’s no more 100%, sometimes it’s again 100% usage. Anybody can help?”
About Disk Usage on Your Computer
Disk Usage (DU) refers to the portion or percentage of computer storage that is currently in use.
