Why Is My Disk Usage At 99? (Causes, Fixes)
Constant high disk usage is a common problem among Windows users.
The typical signs of the issue include extremely slow operations, high load times, and even disk failure.
Your programs and Windows also become laggy and unresponsive at times.
Most users are baffled by what causes these issues because it can be hard to pinpoint the real culprit.
Read on as we explore the potential reasons your disk usage is always at 99% and what you can do about it.
The causes for 99% disk usage range from virus infections, corrupt software, and Intel’s Rapid Storage Technology to virtual memory misconfigurations, auto-scheduled Windows defragment tasks, and Windows search indexes.
To identify the root cause, you need to view your Windows Task Manager and Resource Monitor.
These tools let you see how much disk capacity each process is using.
Once you pinpoint the process consuming your disk capacity, you should end it and check your disk usage again.
If the issue persists, you’re probably dealing with a Windows or firmware-level problem that requires more digging.
Below, we’ll cover the different solutions you can try to resolve your 99% disk usage problem.
How To Identify The Process Consuming Your Disk Capacity
Although the high disk usage problem might seem puzzling, most of the time, it’s not difficult to see which app is eating up all your disk capacity.
That’s because Windows comes with the appropriate diagnostic tools: Windows Task Manager and Windows Resource Monitor.
1. Windows Task Manager
The task manager gives you an overview of your computer’s general resource usage and the services and processes running on it.
To open it, right-click on the Start menu in your taskbar and click Task Manager .
Alternatively, press Ctrl + Shift + Esc to open the task manager.
If the opened window is small, click on More Information to get the full-sized task manager.
Once there, you can sort your processes based on their consumption of disk capacity.
Click on the Disk Usage column header and see the first process.
Then right-click on that process and click End Task .
If that does the trick, you need to take action to fix the issue permanently because it most likely will reappear once you restart your computer.
The general approach is to search the name of the process you just killed to see what it does and how you should deal with it.
Nonetheless, here are a few specific recommendations for the most common situations.
2. Internet Browser
If Chrome, Firefox, or any other browser is pushing your disk usage to the max, the first solution to try is to update the browser.
However, the more likely cause is a poorly coded extension or add-on.
First, kill all the processes corresponding to the browser.
Then type in your browser’s name in the Start Menu and choose New Incognito Window (aka Private browsing in Firefox).
Check the Task Manager to see if your disk usage goes back up.
If it does, completely remove the browser with a tool like Revo Uninstaller , download the latest version of the browser from its official website, and install it again.
Otherwise, you need to identify which extension is causing the high disk usage problem.
Starting from the most recent one, remove the extensions one by one, and restart your browser every time until the issue goes away.
3. Windows Services
Windows services are small programs that manage core aspects of the operating system, such as audio playback and the clock.
Sometimes, these services get corrupted and conflict with one another.
If the process causing your issue is a Windows service, you have to see how your computer is affected by killing it.
Google the service’s name to find out what it does.
Then decide whether or not you can live with the consequences of killing that service.
For instance, the Windows Audio service is responsible for playing sounds and music on your computer.
Therefore, when you kill it, you can’t play music, videos, or games on your computer until you restart the Windows.
To prevent a Windows service from automatically starting after every reboot, follow these steps:
- Open the Start Menu and type in Services . (Alternatively, you can press the Windows key + R and type in services.msc .)
- Locate your intended service from the list.
- Right-click on the service and click Properties .
- From the Startup Type dropdown menu, select Manual .
This way, you can start the service whenever you need it by locating it under services, right-clicking on it, and selecting Start .
Although it might be a hassle, this approach will save you from having to do a clean Windows installation.
4. Critical Windows Component
Sometimes, the process that’s using up your disk capacity is a critical Windows process such as svchost.exe .
The Task Manager doesn’t allow you to kill those processes because they’re necessary for the operating system to keep functioning normally.
In this case, your best bet is to do a clean boot (more on that later) and see if your problem goes away.
If so, you can pinpoint the cause by removing your drivers and programs one by one.
Or you can do a clean Windows installation and save yourself the headache of troubleshooting programs and drivers.
5. Windows Resource Manager
Unlike the Task Manager, the Resource Manager utility lets you look under the hood of your Windows.
You can see how many bytes of data are written and read to each disk in real-time.
It also shows you detailed info on the processes using your disk.
To open the Resource Monitor, press the Windows key + R and type in resmon.exe .
Click on the Disk tab and then the Read (B/sec) column to sort the process by how much data they read from your disk, which directly determines their disk usage.
Once you identify the process causing your issue, the procedure to follow is the same as we explained above.
6. Clean Boot Your Windows
Some Windows processes (and some sneaky malware) don’t appear on the Task Manager or the Resource Monitor.
However, these are usually uncritical Windows components, and they’re more prone to getting corrupted.
Fortunately, Windows comes with a mode that disables these components and only allows the most basic parts of the operating system to load with minimal drivers.
This feature is called the clean boot.
It’s similar to Safe Mode, but it gives you more control over the third-party apps and drivers that load on startup.
You can perform a clean boot as a way to diagnose your problem and isolate the cause.
If the issue persists, your best bet is to reinstall your Windows from scratch and hope that you’re not dealing with a hardware problem.
If the problem isn’t present after a clean boot, you may be able to fix it with some more digging.
Here are the steps to performing a clean boot:
- Press the Windows Key + R and type in msconfig .
- Navigate to the Services tab .
- Check Hide all Microsoft services and click Disable all .
- Navigate to the Startup tab and click Open Task Manager .
- Go through the list and click Disable for all the items.
- Close the Task Manager .
- Click OK on the Msconfig dialog.
- Restart your computer.
Once your computer loads, check the disk usage on the Task Manager.
If the problem disappears, start enabling the services and apps you disabled before.
Enable one service, restart the computer, and check the usage.
You should wait a few minutes to make sure the Windows has fully loaded before deciding if the problem is gone.
This incremental process lets you pinpoint the program or component causing the issue.
However, if the problem persists, return all your disabled apps to their previous state and check the remaining solutions.
7. Uninstall Intel’s Rapid Storage Technology
Intel-based computers usually come preinstalled with a program called Rapid Storage Technology , which claims to increase performance and reliability with SATA hard drives.
It also reduces power consumption and increases battery life on laptops through Link Power Management.
However, that exact feature sometimes causes your disk usage to max out.
To fix it, go to the app’s settings and turn off Link Power Management .
It’ll reduce your laptop’s battery life by a few minutes, but you’ll save your HDD from being constantly active.
Another option is to uninstall Rapid Storage Technology all together.
Windows already has the necessary features to efficiently communicate with hard drives and SSDs.
Therefore, any gains from additional software will be minimal at best.
However, after removing RST from your computer, go to your UEFI BIOS utility and set your HDD connection type to Advanced Host Controller Interface (AHCI) if it’s on IDE.
This change enables a faster connection between your disk and your Windows.
8. Check For Viruses And Malware
It’s common for malicious software to wreak havoc on your system’s resources, including pushing your hard disk to the edge.
Sometimes, they use your system resources for other purposes, such as mining cryptocurrency.
Other times, they just run futile operations.
If you don’t already have one, install an antivirus suite that offers antimalware protection.
Then do a full scan of your system files.
Note that the scan will take a relatively long time because your system’s hard disk usage is already high.
If the scan identifies malicious software, it’ll most likely quarantine the executable files, and your disk usage will return to normal.
Another great option for this situation is Microsoft’s Safety Scanner, a lightweight malware removal tool that you can quickly install.
You can even run the tool from a thumb drive if the malware prevents you from installing it on your Windows.
The scanner is a different tool from Windows Defender, so you’ll have to download and install it separately.
You should always download the latest version from Microsoft’s official website as each download is only valid for ten days.
9. Manually Configure Your Virtual Memory
Virtual memory is a critical component of Windows that acts as a hidden file ( pagefile.sys ) stored on your hard drive.
It’s as large as your entire RAM capacity (e.g., roughly 16 GB if you have 16 GB of RAM installed).
Virtual memory stores the information moved into the RAM that hasn’t been used in a while.
This way, the operating system frees up space on your RAM for newer information.
If the old information is ever needed, some other dated information is moved out of the RAM, and the data in pagefile.sys is moved back in.
As you can imagine, the process is complex and requires different operations.
The file is divided into multiple smaller units called pages to make data management operations easier.
The page size varies between 16 MB and multiple times the size of your physical memory.
Windows automatically detects the ideal size based on how much RAM you have available.
However, the calculations are sometimes wrong, and Windows ends up endlessly swapping files in and out of your hard disk, which translates into 99% disk usage.
To remedy the situation, you need to set the page size manually.
Here’s how to do that:
- Open Control Panel .
- Navigate to System > Advanced system settings .
- Under the Advanced tab, find the Performance section and click Settings .
- Again, navigate to the Advanced tab, find Virtual Memory , and click Change .
- Uncheck “ Automatically manage paging file size for all drives. ”
- Select your Windows drive.
- Click Custom size .
- Set the Initial size to your physical RAM.
- Set the Maximum size to twice the size of your physical RAM.
- Click Set and then OK .
10. Disable Auto-Scheduled Windows Defragment Task
Defragging your hard drive reorganizes how files are stored such that the pieces of a file are put closer to each other.
As a result, your disk’s optical head doesn’t have to travel very far to retrieve an entire file.
The defragging process can be time-consuming and intensive on your disk because it involves moving many file sectors around.
If the defragment process is performed regularly, your disk usage can go high and even up to 99%.
You should check to see if a defragmentation task is scheduled to run on your computer at predetermined intervals.
To view the scheduled tasks on your computer, navigate to Control Panel > Administrative Tools > Task Scheduler .
Once there, look at the folder structure on the left-hand side and expand the following path:
Task Scheduler (Local) > Task Scheduler Library > Microsoft > Windows > Defrag .
Double click Defrag to see the auto-scheduled tasks.
If the Trigger or Next Run Time fields aren’t empty, your hard drive gets defragged regularly, which could cause your high disk usage.
Select the task and then click Disable from the right-hand sidebar.
Restart your computer, wait a few hours and check your disk usage again.
Warning : If you have an SSD, you shouldn’t defrag it because doing so won’t increase your speed. However, because SSDs have a limited number of read/write cycles, it’s better not to waste your limited capacity on a tool that isn’t designed for SSDs.
11. Disable Windows Search
Starting from Windows Vista, Microsoft expanded Windows search functionality to instantly search every folder on your computer.
Although the feature is extremely convenient, it requires creating large address books of your files, called indexes.
Generating those indexes and keeping them up-to-date requires frequently reading your files, which means high disk usage.
You can disable the Windows search feature to see if it resolves your problem.
Here are the instructions to follow:
- Press the Windows Key + R and type in services.msc .
- Locate Windows Search .
- Double-click on it and press Stop .
- If you want to permanently disable the service, choose Disabled from the Startup type dropdown menu.
Alternatively, you can disable the search indexing feature.
You’ll still have the search functionality, but running queries will take longer because your file addresses aren’t stored in an index optimized for speedy retrieval.
Follow these steps to disable search indexing:
- Open This Computer .
- Right-click on your Windows drive (usually Drive C).
- Select Properties .
- Remove the checkmark from “ Allow files on this drive to have contents indexed in addition to file properties. ”
- Click Apply .
- From the dialog that pops up, select “ Apply changes to drive, subfolders and files. ”
Allow the process to finish.
Then restart your computer.
Check your disk usage after a few minutes to see if the problem is gone.

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.

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…
Google ChromeOS.
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…

Step 1: Right-click on the Windows icon and click Task Manager from the prompted start menu.
Step 2: Pay attention to the Disk Usage column in the Task Manager window to see which process consumes the highest disk space.
Step 3: Right-click that process and click End task . You can directly do that in general cases. As for a few specific conditions, please refer to the guides below.
Further reading:
If the target process is a critical Windows process like svchost.exe, you are not allowed to kill it as it is vital to keep the system running properly. In this case, it is recommended to perform a clean boot. Alternatively, you can do a clean install to fix the issue.
If browsers like Chrome and Firefox occupy the maximum disk usage, you should update the browser first. If the poorly coded extension or add-on is the fault, type your browser’s name in the search box and select New Incognito Window .

Method 7: Uninstall Intel Rapid Storage Technology
If your computer is an Intel-based one, it might be preinstalled with Rapid Storage Technology. It boosts performance and reliability with SATA hard drives, reduces power consumption, and extends the battery life of your PC through its Link Power Management.
Nevertheless, these features can cause your disk usage to max out. You can fix the disk at 99 issue by turning off Link Power Management in the settings of the app. Alternatively, directly uninstall Rapid Storage Technology via Control Panel.
Since Windows already has features to communicate with hard drives and SSDs, any gains from additional software will be minimal. However, you are required to go to the UEFI/BIOS utility and set your HDD connection type to AHCI if it’s on IDE after uninstalling Rapid Storage Technology.
AHCI refers to Advanced Host Controller Interface, while IDE stands for Integrated Development Environment. To know the difference between the two modes, click AHCI vs IDE .

Step 3: Click the original disk and then click Next .
Step 4: In the next window, click on the connected hard drive and click Next .
In the prompted warning window, click Yes to continue the copy process.

What can I do about 99% disk usage (only 0.9 MB/s)? [duplicate]
My new laptop is two months old, the first day I got this laptop I noticed this but I assumed it was a bug in Windows 8. However I still have this issue today after reformatting and installing all updates.
The problem is that the disk shows 99% usage from an application...
In this case Dropbox, but the usage is never over 2 MB/s; in this case it is 0.8 MB/s.
What can I do about this?

- How big is the disk and how much free space do you have on it? Are you having actual performance problems or is the issue merely cosmetic? – David Schwartz Feb 6, 2013 at 0:42
- 1 You're just under the users tab which shows the applications that you have running. What about the system? You may have indexing enabled which is causing the initial large amounts of disk reads/writes. – kobaltz Feb 6, 2013 at 0:46

- 1 The combination of very high disk % usage and low speeds is usually quite rare, except when you are doing a lot of random IO (and download email really is not that kind of IO, no idea about dropbox though) or if there are lots of retrys/errors. If those are occuring then you should be able to see them, either in the event log or in increasing S.M.A.R.T values on the drive. – Hennes Feb 6, 2013 at 0:52
- 1 I was told that the percentage you see under "Disk" is the percentage of time the disk I/O queue is not empty. – David Schwartz Feb 6, 2013 at 6:40

I've seen a similar behavior on some computers at work. You have a pretty good chance to be infected with a trojan malware. I'll suggest to run malware and virus scans on your PC.
I had the same issue. It got resolved after updating Intel® Chipset Device Software. Download this from Intel website for your chipset and install to see if it resolves the issue.

- It would be a great idea if you provided a link to the software download. – bwDraco Oct 1, 2015 at 23:27
- This worked for me and also reduced some very repetitive error messages in the system event logs. For me this raises the general question: What does Microsoft Updates take care of and what kind of updates to I have to patiently figure out myself like this one? Or would it be ASUS responsibility in my case to add an updater for the chipset software? My system started to become almost unusable before this update. And now that I have fixed it I still have no clue what was wrong and how it got wrong in the first place. – Patrick Fromberg Apr 23, 2016 at 22:55

Disc running at 99 or 100% in task manager?
I was just playing a game of League of Legends and I noticed that my game was stuttering a bit so I went in to Task Manager to see if Chrome was hogging up all my RAM. That wasn't a problem, but I did notice that my disk usage was up to 99 or 100%. I know for a fact that my HDD isn't anywhere near full, so that isn't a problem. I'm not sure if this is the first time this has happened, but this is the first time I've noticed.
I only had a few tabs in Chrome, a few folders, the League client, and Microsoft Word open at the time that I noticed.
Does anyone have an idea on what could be causing it and what it would mean for my drive/computer?

it could be a virus, or running out of ram, or many other things.

You need to see which process is using the disk % in task manager!
It's very common for HDD to reach %100 usage and lag everything, but while playing this usually doesn't happen unless another task is hogging it up.
I don't believe it's not enough RAM, I have rainmeter installed and it says I'm hovering at about 30-40% tops.
If it were a virus, would I have to format my drive?

not neccesarily, download malwarebytes and Avast! and run a scan with both. (not at the same time)
Would go with Malwarebutes, have good experience with them

Check in your task manager what consumes the disk.
If you use Windows 7, then use Resource Monitor.
Both will tell you what program uses the disk

Disk usage always on 100% or 99% and often the computer runs slowly

On task manager my disk usage always is at 100% or 99% and it often runs slowly. It takes ages to finish loading when I login to windows and it takes long to search my hard drive and open programs.
I have tried
- Wiping out my computer and reinstalling windows
- Replacing my hard drive
- Running chkdsk (no errors were found)
- Running "DISM /Online /Cleanup-Image /RestoreHealth"
- Disabling the Defragmenting scheduled task
- Increasing my paging file size to match the amount of RAM my computer has
This appears to be a software or windows issue.
Any ideas on how to fix this?

I had the same problem. I shut off the windows defender av schedule, which was scanning my computer every time i booted it up. You can click on Disk at the top to bring up the process that is using your disk the most.
Posted 14 March 2018 - 04:32 PM
Clicking "disk" to see what is taking up the most hard drive usage does not work. I am not shown any meaningful data.
Windows Defender and Windows Firewall is disabled on my computer. I am only using one security software on my computer which is Comodo Internet Security.

Man that is a lot of chrome processes lol. Does your disk usage go down if you were to close chrome?
Posted 14 March 2018 - 04:54 PM
There is supposed to be lots of Google Chrome processes, as Chrome is supposed to run as multiple processes, to load websites faster. Even if you only have 1 tab open, it does this.
No it does not go down. It stays the same at 99%

Hit your window key and type in sleep and select the power and sleep option. on the right hand side you see advanced power options, click it. In the next window on the left hand side you will see creat a power plan. Click it . Check High performance and hit next, leave the next screen at its default settings and then create. If this does not work then there is a list of several options that you can try.
Posted 14 March 2018 - 05:18 PM
I have figured out how to change my power plan settings. I have changed my power plan to High Performance and the problem is now fixed.
This has fixed the problem. Thank you. My power options were set to HP Recommended.

Please perform the following and let us know if the CPU usage is still 100% then we can help narrow it down.
How to perform Clean Boot
To enter a clean boot state, type msconfig in start search and hit Enter to open the System Configuration Utility. Click the General tab, and then click Selective Startup . Clear the Load Startup Items check box, and ensure that Load System Services and Use Original boot configuration are checked.
Next, click the Services tab. Select the Hide All Microsoft Services check box. Now click Disable all .
Click Apply/OK and restart the computer. This will put Windows into a Clean Boot State.
If the clean boot helped you fix the error, Great! Else in the General tab, also click to clear the Load System Services check box, click Apply/OK and restart.

Posted 16 March 2018 - 12:44 PM
Also a good easy way that might give us some clues to what is has the most disk activity.
1. Type Resmon into Start or the Run box and open Resource Monitor
2. Select the Disk tab. This will give you a display with “Processes with disk activity
3. Provide a Screenshot

9 Finest Ways to Fix 99 Disk Usage Issue
Is your computer loading slow or has become less responsive. 99 % Disk usage or 99 Disk usage or more than 95% Disk usage may be the cause for it. The applications are slow as a turtle and your system suddenly restarts/shuts down itself.
Today, we will talk about how to check if your system has extremely high disk usage and the various ways to tackle this nuisance.
What is a Disk:
A hard disk drive is used for storing data . It can also do data retrieval. Both storage and retrieval are done on disks coated with magnetic materials. Data is accessed randomly. Individual blocks can be accessed in any order. It is a type of non-volatile storage . It was first introduced by IBM. The main characteristics of a disk are:
Capacity: measured in terms of GB or TB
Performance: This is measured in terms of RPM (rotations Per Minute) usually it is between 10,000rpm and 15,000 rpm. The high the rpm values, the better will be the performance.
What is 99 Disk usage:
Usually, the allocated space in normal and old computers ranges from 50 to 150 GB, while modern and gaming computers have near to 1TB of space.
What happens when the applications and software stored on those disks exceed 95% of the disk storage The system slows down, apps take a lot of time to load and the mouse slows down. At 99 and 100%, the system shuts down or restarts due to reaching its highest capacity.
What causes 99 Disk Usage:
Various reasons can lead to causing 99 Disk usage and system shutting down. A few of them are:
- Overload of applications and software.
- Unwanted folders and files consuming memory.
- Outdated drivers.
- Malwares or spywares.
- Corrupted hard drives.
- Corrupted Superfetch.
- Many programs running simultaneously.
- Windows Defrag.
9 Ways to rectify 99 Disk usage:
The below solutions will discuss how to rectify the sudden shut down caused by 99 Disk usage:
Uninstall applications that are not required:
- Open Control Panel .
- You can type it on the search box, situated at the task bar.
- Click on the “ Uninstall a program ” option.
- The various applications and software of your system will be visible now.
- Right click on those which you no longer require, and choose uninstall.
Clean unnecessary folders and junk:
You can manually enter into C:/ drives and all other drives to look for unnecessary junk and duplicate, which will take a lot of time.
Or you can choose to use the “Clean System Junk” features provided by Avast anti-virus or a few other software.
- Download and install Avast anti-virus from the official site here .
- If your system has junk, it will appear below and will ask to RESOLVE by cleaning the junk.
- You can either choose that, or perform a SYSTEM SCAN.
- Wait for some minutes till it gets completed.
- Choose the option to delete the files.
Update your drivers:
- Search for “Settings” on the search panel and navigate through:
- Update & Security -> Windows Update -> View optional updates -> Driver updates .
- Select all the Drivers, then hit the Download and Install button.
- Restart your computer.
Do a full system anti-virus check:
There can a possibility of virus infections or malware junk in your system that can cause heavy 99 Disk usage. This can be resolved by downloading a system scanning software like McAfee anti-virus or Avast anti-virus software.
Disable or uninstall “Superfetch”:
- Open Command Prompt with administrator mode.
- Run the command:
- net.exe stop superfetch
- Press Enter.
- If it shows invalid, then use:
- net.exe stop sysmain
Stop unnecessary programs from running:
- Open Task manager (Ctrl + Shift + Esc).
- A list of ongoing and backgroung applications which are currently running will be shown.
- Right click on few and select “ END TASK”.
Disable Windows Defrag:
- From the Search Panel, fetch for Task Scheduler.
- Navigate through: Microsoft ->Windows-> Defrag.
- Delete or disable this software.
Enable High Performance:
- Choose the Power Options, after hitting (Win + X).
- Navigate through : Power & Sleep -> Additional Power Settings -> High Performance.
Replace the broken hard drive:
A software or malware might have corrupted your drive, and the only option left is to replace this drive with another one. Overheating can also damage a few parts of the disk drive, even though the temperature is not too high for the system to shut down. Improper functioning of the disks can lead to 99 Disk usage.
Resolve 99 disk usage on windows 10 during startup:
This happens when some of the services and software are not in the manual start but the automatic start when the system restarts. To stop this automatic start of services when the system turns ON, navigate through the control panel -> Administrative Tools -> services
In here, you will find a lot of services. You can change the startup of services from automatic to manual.
How can to my disk usage be 99% when I use only one program?
Perform a Clean Boot . If you are not able to do it in the normal mode, then enter in the safe mode. You can enter in the safe mode by:
- Open the Run dialog box.
- Type in it “ msconfig”.

Didn't find what you were looking for? Ask the community
Task manager says disk drive is always at 99%.
I'm using an HP Pavilion laptop. I can't figure out the exact model number at this time. I've tried every fix that I can think of, and everything on the first page of Google and then some. I just finished a clean install of Windows 10 and the problem still persists. I really don't know what to do at this point. No matter what is open it's always there at 99%.
I'm assuming it's the HDD going out because the problem is still there, but I ran a scan of the drive before I did the clean install, and Windows said the drive was fine.
Any ideas? I'd prefer not to take it apart/send it to a professional, but it's starting to look like it's my only option at this point.
Go to system -> notifications-> disable tips and tricks about windows 10 and find a tutorial on how to disable superfetch.
Thanks, I'll give this a try. Thought I already tried this before, but I can't remember if I did.
After I disable superfetch, should I restart my computer to see if it takes effect? It doesn't seem to be helping right off the bat.
Edit: now it seems to be doing better.
What programs are using the most disk usage? You can check using Resource Monitor. You may need to replace the hard drive with an SSD
Honestly, it's none of them. Something using as little as 2MB/s will set it to 99%. Even with nothing but task manager open. Opening pretty much anything is a nightmare.

How to troubleshoot 99% or 100% disk
At times this computer (windows 10 pro version 1607 x64) becomes sluggish and viewing task manager displays 99% or 100% disk.
Today I opened the resource meter and this was its view moments ago::
https://1drv.ms/i/s!AhdfDD74t_q2iiBeq_w0eaM_wp0f
The disk is now 0% and it took more than 20 minutes to temporarily self correct. At the time of the 99% or 100% disk the CPU and RAM were 4% and 8% respectively.
There were multiple browsers open as well as software earlier in the day. Task manager did not display any open browsers at the time of the 99% disk. Windows update had been run as well as windows defender earlier in the day. Clean boot was used on numerous boots including the last one today. Ccleaner routinely runs without problems and when it was running extremely slow I viewed task manager then resource meter. Then I recorded the information with the snipping tool. Again the 99% or 100% happens most often spontaneously. I've not been able to find the use or any browser or software that triggers the 99% or 100% disk.
Too often the disk remains at 99% or 100% for long periods of time and requires a reboot to interrupt the 99% or 100% disk..
Sometimes even after a reboot it may display 99% or 100% disk in task manager.
SFC /scannow displayed no integrity violations
Dism /online /cleanup-image /restorehealth completed successfully.
This is event viewer: https://1drv.ms/u/s!AhdfDD74t_q2iiL1cJwxNgTru1kM
This is msinfo32: https://1drv.ms/t/s!AhdfDD74t_q2iiE5tlAE9GobuzqR
So far I have been using clean boot: win + r then msconfig then services then hide all Microsoft services then un-check all remaining items. Even with selective boot this 99% or 100% repetitively happens.
Was anything found in the resource meter that can be used to work up and fix the 99% or 100% disk? Is it some hidden item that is not displayed in task manager or resource monitor that is producing the 100% disk?
With it running in clean boot is the source a Microsoft item?
What other steps would be helpful to work up this 99% or100% disk problem and fix it?

What Causes 99% Disk Usage?
One of the most common causes of disk usage is spam. This can cause your computer to use 100% of the disk space. One way to stop spam is to use a spam filter. Another way to stop spam is to use a spam blocker. Another cause of 99% disk usage is due to viruses and malware. There are two ways of dealing with this. One is to use a virus scanner. The other is to use a malware scanner. Another cause of 99% disk usage is files that are not being deleted. The best way to get rid of these files is to use a disk cleanup program.
Symptoms Of 99% Disk Usage?
When running a disk-intensive program, you may notice that your disk usage is high. This can be caused by a number of factors. For example, your disk usage is high if you are running a disk-intensive program and you have a lot of files on your hard drive. If you are using a lot of RAM, your disk usage will be high as well. However, if you use a lot of RAM, you will also see high CPU usage.
What Can I Do To fix 99% Disk Usage On My PC?
The first thing to do is to run the disk check utility in Windows. This will allow you to find out if the disk is actually almost full, or if it is just a problem with the way your computer is being used. If the disk is almost full, you can try to defragment it. If it is not, you may have to try to uninstall some files that are using up a lot of space. If you are still experiencing high disk usage, you can try to clean up your hard drive and defragment it again. If this does not work, you may want to try a Windows repair.
Identify The Process Consuming Your Disk Capacity
Although the 99% disk usage problem might seem puzzling, most of the time, it’s not difficult to see which app is eating up all your disk capacity. That’s because Windows comes with the appropriate diagnostic tools: Windows Task Manager and Windows Resource Monitor.
1. Windows Task Manager
Windows manager provides you with an outline of your PC’s overall asset use and the administrations and cycles running on it.
To open it, right-click on the Start menu in your taskbar and click Task manager.
On the other hand, press Ctrl + Shift + Esc to open the Task manager.
Assuming the opened window is little, click on More Data to get the regular errand administrator.
When there, you can sort your cycles in light of their utilization of plate limit.
Click on the Circle Use segment header and see the first process.
Then right-click on that process and snap End Errand.
Assuming that gets the job done, you want to make a move to fix the issue forever in the light of the fact that it undoubtedly will return once you restart your PC.
The general methodology is to look through the name of the cycle you just killed to see what it does and how you ought to manage it.
In any case, the following are a couple of explicit proposals for the most well-known circumstances.
2. Internet Browser
In the event that Chrome, Firefox, or some other program is pushing your circle use as far as possible, the primary answer for the attempt is to refresh the program.
Be that as it may, the more probable reason is an inadequately coded expansion or extra.
To begin with, kill every one of the cycles compared to the program.
Then type in your program’s name in the Start Menu and pick New Incognito Window.
Actually, take a look at the Task manager to check whether your circle use returns up.
On the off chance that it does, totally eliminate the program with an instrument like Revo Uninstaller, download the most recent variant of the program from its true site, and introduce it once more.
In any case, you really want to recognize which expansion is causing the high plate use issue.
Beginning from the latest one, eliminate the expansions individually, and restart your program each time until the issue disappears.
3. Windows Services
Windows administrations are little projects that oversee center parts of the working framework, like sound playback and the clock.
Once in a while, these administrations get ruined and struggle with each other.
On the off chance that the cycle causing your issue is a Windows administration, you need to perceive what your PC is meant for by killing it.
Google the assistance’s name to figure out what it does.
Then, at that point, conclude whether you can live with the outcomes of killing that help.
For example, Windows Sound help is liable for playing sounds and music on your PC.
Hence, when you kill it, you can’t play music, recordings, or games on your PC until you restart Windows.
To keep a Windows administration from naturally beginning after each reboot, follow these means:
- Open the Beginning Menu and type in Administrations. (On the other hand, you can press the Windows key + R and type in services.msc.)
- Locate your expected assistance from the rundown.
- Right-click on the assistance and snap Properties.

Along these lines, you can begin the assistance at whatever point you really want it by finding it under administrations, right-tapping on it, and choosing Start.
Despite the fact that it very well may be an issue, this approach will save you from being required to do a spotless Windows establishment.
4. Critical Windows Component
Some of the time, the process that is spending your disk capacity is a basic Windows component, for example, svchost.exe .
The Assignment Director doesn’t permit you to kill those cycles since they’re vital for the working framework to typically continue to work.
For this situation, your smartest choice is to do a spotless boot (favoring that later) and check whether your concern disappears.
Provided that this is true, you can pinpoint the reason by eliminating your drivers and projects individually.
Or on the other hand, you can do a perfect Windows establishment and save yourself the migraine of investigating projects and drivers.
5. Windows Resource Manager
Dissimilar to the task manager, the windows resource manager allows you to look in the engine of your Windows.
You can perceive the number of bytes of information that are composed and perused to each circle continuously.
It likewise shows you definite data on the cycles utilizing your plate.
To open the Asset Screen, press the Windows key + R and type in resmon.exe.
Click on the Plate tab and afterward the Read (B/sec) segment to sort the interaction by how much information they read from your circle, which straightforwardly decides their circle use.
When you recognize the interaction influencing your issue, the methodology to follow is equivalent to what we made sense of above.
6. Clean Boot Your Windows
A few Windows cycles (and some slippery malware) don’t show up on the Task Manager or the Resource Monitor
Nonetheless, these are generally careless Windows parts, and they’re more inclined to get ruined.
Luckily, Windows accompanies a mode that impairs these parts and just permits the most fundamental pieces of the working framework to stack with negligible drivers.
This component is known as the spotless boot.
It’s like Protected Mode, yet it gives you more command over the outsider applications and drivers that heap on startup.
You can play out a spotless boot as a method for diagnosing your concern and disconnect the reason.
On the off chance that the issue continues, your smartest option is to reinstall your Windows without any preparation and trust that you’re not managing an equipment issue.
In the event that the issue is absent after a perfect boot, you might have the option to fix it with some real digging.

In the event that the issue vanishes, begin empowering the administrations and applications you handicapped previously.
Empower one assistant, restart the PC, and really look at the utilization.
You ought to stand by a couple of moments to ensure the Windows has completely stacked prior to choosing if the issue is no more.
This steady cycle allows you to pinpoint the program or part causing the issue.
Notwithstanding, assuming that the issue continues to happen, return all your crippled applications to their past state and really look at the leftover arrangements.
