The first and foremost thing you should do before doing anything is to check what actually is causing this 100% disk usage uses in windows 10.
There is a quick and easy way that lets you check what is causing this error. and you can do it using the windows task manager.
Follow these steps to check the issue in the windows task manager.
- Open windows task manager by using the
ctrl + shift + ESCkey shortcut.
Alternatively, you could also open the task manager by searching for the task manager in Windows search manager.
- Once the task manager is opened. In the processes tab, click on Disk columns and see which process is using the 100% disk usage error.
If the problem is caused bu the third party software then just ending the process will fix the error.
If you are not sure about the error and the problem is with other services of windows 10 then follow this step by step guide.
One of the most common issues for causing high disk usage is resource hunger google chrome. Its web page pre-load feature is the one that is causing this error in windows 10.
So, if notice Google Chrome in task manager is causing this 100% disk usage error. then turning off this feature most probably fixes the error.
To disabled pre-load features follow the steps.
Open Google Chrome
On the right upper corner click on three dots and then click on settings.
Now on the left side, click Privacy and Security and then click more.
- Now disable/uncheck Preload pages for faster browsing and searching.
After using this setting off, restart the browser and check if it fixed the high disk usage issue.
If not, then one of the malicious extensions might also be causing the issue, they disabling the extensions and check if the issue persists.
If after doing all these steps, still the problem exists and you can see Google chrome is causing 100% disk usage in the task manager. then its time to uninstall it and move to other browsers like Firefox or Brave.Brave is the perfect choice if you love the chrome ecosystem as it built on top of Google chrome and is more [privacy-oriented](/best-private-search-engines/) than Chrome.
Moreover, you don't need to use any adblocker or anything, it has all built-in.
The second and one of the main reasons for causing high disk usage in windows 10 for many users is Skype. If you don't use skype then it is better to uninstall it as it comes pre-installed with Windows 10.
The main reason skype is responsible for this issue has to do with write permission for ALL APPLICATION PACKAGE group.
So to fix 100% disk usage follow these steps:
First of all, you need to quit skype from the taskbar. So, Right-click on skype icon and click Quit.
Now run window by pressing Windows key + r shortcut and type or paste the following location. You can also head over to this location manually
C:\Program Files (x86)\Microsoft\Skype for Desktop
Right-click on the "Skype.exe" application file and choose "Properties".
Under the "Security" tab and select "ALL APPLICATION PACKAGES" and click edit.
On the security window, select ALL APPLICATION PACKAGES, and check the "Write" box. And then click apply and then ok.
Now check if the problem still persists in the task manager. If the problem is with Skype then doing this will fix the error.
Windows search can be quite handy but sometimes it can also result in a 100% disk usage problem in windows 10.
So, if the disk usage error is because of windows search service then you can disable it. What causes the error is due to the search loops bug in the windows.
But I would recommend temporarily disable the search service and see if the problem is fixed. If the problem is fixed then you should permanently disable the Windows search service.
If not, then there is something else that is causing the high disk usage issue.
- Open Command prompt as admin by pressing Windows + X key and then selecting Command Prompt (Admin).
- Now type the following command and press enter.
net.exe stop “Windows Search”
Now check the disk usage in task manager, if the issue is fixed, then the Windows search service is causing 100% disk usage, so you might want to permanently disable search service.
So proceed to the second part.
And in case, the problem is not fixed, then there is nothing wrong with the search service and you can re-enable it by restarting your PC or using the following command in cmd.
net.exe start “Windows Search”
- Open window run by using the Windows + r key shortcut. and type "services.msc" and hit enter.
Now locate "Windows Search" and double-click on it to open the Properties Window.
Under the General tab, change the startup type to disabled.
- Now click Apply and OK.
Check the task manager to see if the problem is fixed.
SysMain, formerly known as Superfetch is another windows 10 service which can result in a 100% disk usage issue in Windows 10.
If you have heard about Superfetch that you would know that it helps to maintain and improvise system performance over time. However, sometimes it results in high disk issues. So to disable it follow the steps:
Press Windows + X key and open Command prompt (Admin).
Now type the following command and press enter.
net.exe stop sysmain
After running this command, wait for some time and open task manager to see the disk usage is getting reduced or not.
If the problem persists, then this service may not be causing the disk usage problem.
Please note that you can use "services.msc" to disable the SysMain service as we have done with the window search service.
But make sure to look for SysMain in the service list not Superfetch. Superfetch is renamed as SysMain with recent updates of Windows.
