What is svchost.exe and why it’s running in Windows OS?

When you bring up Task Manager by pressing Ctrl + Alt + Del (in Windows 7), or Ctrl + Shift + Esc (in Windows 8, 8.1 and Windows 10), you will notice a lot of running processes there, including svchost.exe. So, what exactly svchost.exe is and why it’s running on your Windows computer?

Firstly, lets me introduce to you how svchost.exe work! However, to get started, you have to know what is standing behind this file and those processes that are running in the Task Manager.

Let me ask you a question! Have you ever heard about DLL file before? If you don’t know, DLL files are files that contain common functions of Windows operating system. Windows or other programs can use functions on those files to work.

Unfortunately, those DLL files can’t be automatically opened and run themselves. Instead, they will need assistance to call functions from those DLL files. That is the reason why Microsoft designs svchost.exe process.

Why there are a lot of svchost.exe processes are running on your computer?

To avoid any corruptions when something goes wrong with a part of Windows, Microsoft divided and group up a few functions to a particular svchost.exe process.

By that, when a svchost.exe corrupts, all other svchost.exe processes are still working well, without any issues.

What should I do when svchost.exe uses a lot of your computer resource?

Typically, most of the svchost.exe processes won’t use much computer resources. They just use a few megabytes of RAM, as well as 2% to 5% of CPU usage.

However, sometimes those svchost.exe processes were eaten a lot of CPU resources or memory, especially svchost.exe (netsvcs) or svchost.exe (localsystemnetworkrestricted). When you open Task Manager, you might have noticed that your CPU usage is going up, about 50% – 70%, and they might have used up to 90% of your memory.

When you are having this kind of problem, the first step you should take is to find out which program that was using the svchost.exe. From that result, you can easy to diagnose and take an appropriate solution to fix the issue.

As an example, if Windows Update stays behind the “svchost.exe” process that was eating your computer resource, then you should stop it from running, and then use Troubleshooter tool to resolve the problem automatically. Or if it was another third-party program, just close it and re-open to troubleshoot the error.

Things you shouldn’t do to avoid this kind of issues?

From my point of view, high CPU usage problem with the svchost.exe process is always related to Windows Update or functions in Windows operating system. Therefore, you should check for updates and install all latest updates to fix bugs and enhance the system performance.

If after installing those available updates and getting this issue, uninstall them and refresh the update process in order to re-download and re-install updates.

If you use Windows 10, it’s easy to do by accessing Settings -> Update and then choose Reset this PC.
