Why svchost.exe (netsvcs) high CPU usage problem occurs?

Have you ever wondered what svchost.exe is and why it is running on your Windows computer? If you open Task Manager and look at the Processes tab, you may notice there is more than one svchost.exe running on your Windows PC, and you can’t just stop it by killing it within Task Manager.

So, what is it and why is it running on your computer?

According to Microsoft, svchost.exe is a generic host process name for services, which run from dynamic-link libraries. Microsoft has moved all functions of Windows services into dynamic-link library files (the .dll file). However, you can’t execute a .dll file directly from Windows. It must be loaded from an executable (.exe) application. That’s the reason why svchost.exe was born.

Why is More Than One svchost.exe Running?

You might know Windows has a lot of services,  and if you have ever looked at any of them, many of them are required when booting the Windows operating system (OS).

Therefore, if Windows only uses one svchost.exe instance to load all services, then a failure might bring down the whole Windows system. In this case, Microsoft organized services into logical groups, and each svchost.exe will be created for each group.

2. Disable Services That Causes svchost.exe High CPU Usage Issue

As I mentioned above, the svchost.exe process is required by many programs and services to assist them to run.

Therefore, if you want to find the reason why it uses a lot of CPU/RAM resources, you must find the program or service that runs under the particular svchost.exe process.

After that, disable the service or uninstall the program that caused the high CPU usage problem.

To determine the program or service that is using a lot of your CPU/RAM, follow these instructions:

In Windows 7:

  1. Press Ctrl + Alt + Del and then select “Start Task Manager“.
  2. Click on the Processes tab.
  3. Choose the svchost.exe process that is using too much resources on your computer.
  4. Right-click on it and choose “Go to service(s)“.
  5. It will automatically switch to the Services tab and highlight the service that uses the selected Svchost process.
  6. Press the Services button to access Windows Services.
  7. Locate the service that’s using the svchost.exe process and then right-click on it, and select “Restart” to reboot it.

In Windows 8, 8.1 and Windows 10:

  1. Press Ctrl + Alt + Del and then choose “Task Manager“.
  2. Click on the Details tab.
  3. Select the svchost.exe process that is using too much resources on your computer.

  5. It will automatically highlight the service that uses the Svchost process. Right-click on it, choose “Restart” to reboot the service.

Restart a service in Task Manager

After restarting, if the Svchost process is still using too much CPU/RAM resource, you should stop it. To do so, right-click on it, and choose “Stop“.

You can also disable a particular service by right-clicking it, and choose “Open services“.

Find it from the list of Windows services, and then double-click on it. Select “Disabled” from “Startup type” drop-down list. Then click on the “Apply” button, and then the “OK” button.

4. Diagnose and Troubleshoot Windows Update Issues

According to Microsoft, when Windows Update checks for new updates or downloads the update in the background, the svchost.exe high CPU usage issue might occur.

Tip: Before using any methods below, you can uninstall Windows updates that installing lately. In most cases, new updates aren’t compatible with your current settings, or apps, and cause this high computer’s resource issue. So it’s better to uninstall (rollback) those updates to see where the problem come from.

To diagnose and troubleshoot Windows Update issues, perform the following instructions:

Step #1: Clean Up Windows “SoftwareDistribution” Folder

The “SoftwareDistribution” directory is the place where Windows OS stores the downloaded updates. If something goes wrong while downloading the updates, or files in this folder are corrupted, you will encounter issues during the upgrade process, including high CPU usage problem.

As a result, the first step you have to do is to force Windows OS to re-download new updates. To do so, you need to clean up the SoftwareDistribution folder. Follow the following instructions to clean up the folder:

  1. Press Windows + R to open the Run dialog box.
  2. Fill out “services.msc” without the quotes and press Enter.
  3. In the Services window, search for “Windows Update“, right-click on it and choose “Stop“.
  4. Go to C:\Windows, find SoftwareDistribution folder and then delete it.
  5. Reboot your Windows PC and check for Windows updates.

If the Svchost high CPU issue remains, move to the next step.

Step #2: Use Windows Update Troubleshooter

You can visit this web page from Microsoft.com to download the Windows Update Troubleshooter.

After that, run it and choose “Detect problems and apply the fixes for (Recommended)” option to let the program automatically identify and fix issues with Windows Update if any exist.

Once it’s completed, let’s check for updates again as to whether the Svchost.exe (netsvcs) high CPU issue persists.

You should also download the latest version of Windows Update Agent and install it on your computer. Visit here to download it.

In case the Svchost.exe (netsvcs) high CPU problem occurs after installing Windows updates, I would recommend that you uninstall those updates because that could be the cause of this issue. Besides, you can use DISM (Deployment Image Servicing and Management) or System Update Readiness to fix Windows Update errors.

Can svchost.exe Process Be A Virus?

If the location of the svchost.exe file is in the C:\Windows\System32 folder, then there is nothing to worry about.

Open svchost.exe file location

Any processes named “svchost.exe” but stored in another folder instead of “System32” can be considered as a virus or malware. If you want to be sure about the svchost.exe file, visit VirusTotal.com, submit the file you want to check and let them verify it for you.

Scan svchost.exe for virus or malware

However, if you doubt that your computer can be affected by viruses or malicious programs, you should use an antivirus to do a full scan.

If you don’t have any antivirus program on your computer, here are two recommendations from me: top free antivirus, and top premium antivirus.

I hope this guide has helped you to fix the Svchost.exe high CPU problem. If you have any questions regarding this article or Svchost.exe, let me know by leaving your comment below.

    Is there any way to bypass this issue in case it comes from the build #1067? I’ve recently upgraded to 1067 and got this issue.

    I would like to stay at this build version, but don’t want to encounter this high CPU issue from svchost.exe process.

      It depends on each case, and without further information, I can’t help you much on your case. If uninstalling the build 1067 helped to resolve the issue, then I would recommend you to do so and wait for the next update from Microsoft.

    Is it safe to remove SoftwareDistribution folder? Is there any bad result when removing it, such as corrupted Windows operating system?

    I would like to resolve this problem as soon as possible. However, I worry that I will make it more worst than good.

    1. Eric says:

      Don’t need to worry Patel. Removing this folder doesn’t affect your Windows operating system or your computer. It’s a folder that contains Windows Update files, the downloaded one. When you clean up this folder or even remove it, the next time when Windows Update runs, it will re-create this folder again.

      So, just remove or clean up the folder to help you resolve the issue.

    In Step 2 point 7 your instruction is: “Locate the service that’s using the svchost.exe process and then right-click on it, and select “Restart” to reboot it.” How do you tell what service is using the svchost process?
