Disk usage is a measure that operating systems (in this case Windows 10) have developed to know what percentage of the disk (where the operating system is installed) is in use, which increases or decreases depending on the applications that are running simultaneously. On the other hand, svchost.exe is a host service process that must always be active, which generally has normal behavior on the computer but can sometimes exponentially increase disk usage. Here you will know the reason for this problem and various ways to solve it.

Part 1: Fix High Disk Usage of Svchost.exe in Windows 10

Q: My computer has become slower since a few days. I have noticed in the task manager that the disk usage is 100% and only the process "svchost.exe" occupies more than 90%. Could you help me to solve this problem?

Each disk performs write and read processes; these can have a maximum write / read speed on average of 100 mbps to 150 mbps. Each application active on the computer is constantly reading or writing, so if the sum of all these applications reaches the maximum write / read speed of the disk, it will have represented a 100% disk usage.

Depending on the application, it will take up disk usage, most of them take up very little disk usage. However, there are others that are quite demanding in this regard. Sometimes, some processes that tend to take up very little disk usage change their behavior and start to be problematic; an example is svchost.exe which, in a normal state, will consume very little mbps on the disk. However, there may be factors that alter this service host and that it becomes a process that occupies a high percentage of disk usage and that in this way your computer works very slowly.


Part 2: The reason for the problem

The fact that svchost.exe occupies a large part of disk usage can be due to several factors, below I will mention some of them:

  1. Svchost.exe is affected by a malware or virus: There are malware that pretend to be unnoticed by the user. This means that they can be installed on your computer and that they are activated with the same name as svchost.exe, with the great difference that their presence is of course intended to harm your computer. So, in this case, svchost.exe is not the one consuming disk usage, but a malware or virus that has claimed the same name. Doing a scan with an antivirus or antimalware will be very useful to detect the malicious program.
  2. Others: There are other situations why svchost.exe can consume a lot of disk usage space. One of them is because as it is a host service, it is made up of several services and these are sub-processes that can excessively increase the mbps if there are errors or alterations in its operation. Another common reason for this behavior of svchost.exe is because there may be large log files, which can be used by this process.

Regardless of why svchost.exe can occupy a large space in disk usage, there are several alternatives to solve it. In the next part you will be shown several of them.


Part 3: How to Fix High Disk Usage of Svchost.exe in Windows 10

To fix high disk usage of svchost.exe in Windows 10, below you will learn several methods:

Method 1: Run a full antivirus scan

An antivirus can help you detect which malicious file is causing the virus to activate. Windows, through its own antirivirus sofware (Windows Firewall) can also do it; Below I will describe the steps to make a scan using this tool:

Step 1: Open Windows Defender settings

Click on the Windows icon and type “Windows Defender” on the search box. Then click on “Windows Defender settings.”

Step 2: Open Windows Defender Security Center

Now click on “Virus & threat protection.”

Step 4: Start scanning

Click on “Scan now” and Windows Defender will search for virus and malware that may cause problems to svchost.exe.

Method 2: Check if any Windows 10 update is pending or not

If you don't keep your operating system updated, in addition to reducing your security, it can make processes (like svchost.exe) not work as indicated, facilitating errors and problems. To check if you have pending updates in Windows 10, follow these steps:

Step 1: Open Windows settings

windows-updates-image-1

Click on the Windows icon and then click on the gear icon to open Windows settings.

Step 2: Open Update & Security window

On the settings window, click on “Update & Security.”

Step 3: Check for updates

On this window just click on “Check for updates.” If there are pending updates, they will be installed automatically.

Step 4: Wait and restart

If Windows installed updates, you have to wait. Depending on the size of the update, you will have to wait just a few or some minutes. Afterwards restart your computer and check if svchost.exe works as it should.

Method 3. End svchost process through Resource Monitor

You can end any svchost process from the Task Manager, but you should bear in mind that any Windows process that you end through Task Manager will automatically start again when you restart your computer.

Step 1: Open Task manager

With the help of the Windows "Task Manager" you can end any process just by right-clicking on its name and selecting the "End Process" option.

Method 4. Disable Windows update service

The problem is likely due to Windows update constantly searching for updates or trying to install them. To fix this problem, you can disable the Windows Update service from Windows Service Manager.

Step 1: Open the Services manager

Method 5. Clear event viewer logs from your computer

Event Viewer is a Windows service that allows you to manage and view an event log which is commonly used to find errors in the system. To clear event viewer logs follow these steps.

Step 1: Run Command Prompt as administrator

Once Command Prompt is opened in administrator mode, type the following code and press "enter"

for /F "tokens=*" %1 in ('wevtutil.exe el') DO wevtutil.exe cl "%1"

Method 6. Fix your Windows update issues

Windows has a tool called Troubleshoot that allows you to fix Windows update problems automatically. To use this tool, just type "Troubleshoot" from the Windows menu and click on its shortcut. Once this is done, you will see the "Windows Update" option within the "Troubleshoot" menu. Click on the “Windows Update” option and the tool will guide you through the repair process.

Method 7. Disable background intelligence transfer service (BITS)

Disabling the background intelligence transfer service can considerably reduce disk usage, but you should bear in mind that if you use the “Task manager” to end the process, it will automatically start again every time you turn on your computer, therefore, I recommend to disable the service through the Services Manager. Below I will show you how to do it.

Step 1: Open the Services manager

disable-bits-service-image-1

You can access the services configuration by pressing Win + R and typing "services.msc".

Step 2: Disable background intelligence transfer service

disable-bits-service-image-2

Once inside Services manager, you should search for the “Background intelligence transfer service” service, right-click on its name and choose the “Properties” option. This will open a window from which you can disable the service.

Method 8: Clean install Windows 10

If with the previous methods you did not manage to solve the problem, you can choose to reformat your device. This method will delete all the information on the disk and create a clean installation of the operating system, thus suppressing any errors, viruses or fragmented segments on the disk that may be affecting the performance of the device.

To perform a clean installation of Windows 10, you will need to download the Windows 10 installation tool from its official website. The most common and recommended method is to use a USB to store this installation tool. Once you have created your Windows 10 installation device, you will need to boot from USB to begin the installation. Now all you have to do is select “Custom” installation type, format the device and follow the steps indicated by the Windows 10 installer.

Restore the information you had stored on disk

As I mentioned earlier, performing a clean installation of Windows 10 will erase all the information you had stored on your device, however, this problem is easy to solve thanks to Recoverit. This software is capable of reconstructing and recovering all the information on a disk based on the residual information. It will be enough to do a couple of clicks and the software will take care of recovering your data.

Conclusion

Windows 10 was designed to make the user experience extremely comfortable and efficient, to achieve this goal, it was necessary to implement services that were responsible for performing optimization tasks automatically, but there is also the possibility that these services hinder the performance of your computer.
