Svchost.exe: what is it and how to fix errors with it

If the computer is slow and in the Processes tab in the Task Manager, you see that one or more processes svchost.exe will load the processor 100%, then this is a solvable problem. It is typical for Windows 7, but it can sometimes appear in newer versions of the OS.

What is svchost.exe?

With it, the system loads the components stored in dynamic dll-libraries. This appeared in Windows 7 and it is here that the process most often slows down the PC significantly.

How do I fix an error with svchost.exe?


First, check that all Windows updates are installed – sometimes svchost.exe overloads are caused by the fact that not all updates were downloaded, and the OS cyclically “returns” to them. If it does not help, then do the following.

  1. Perform a full cleaning and testing of the OS. The process often uses viruses to gain access to computer resources. This is detected if the svchost.exe line in the “User” column indicates something other than Network Service, Local Service and System. Run the scan of all disks with your antivirus software. Then use antivirus utilities like Rescue Disk or CureIt. Another thing is to press the combination of keys Win + R, enter the msconfig query and run it with Enter. In the “System Configuration” window, go to the “Startup” tab and there should not be a “svchost.exe” field and a check mark next to the first criterion “Startup Items”. If there is a checkmark, then remove it. Save the change – the system will ask about it and better choose the reboot.
  2. Investigate the problem with Microsoft Sysinternals Process Explorer. Download it from the official website and install. This is a kind of “pumped” Task Manager. After running the utility, find the line svchost.exe in it, which will load the system and move the mouse over it. A pop-up window will tell you all the details about the problem process. The easiest way to disable this process, but with a high probability after the overload problem will appear again. It is preferable to investigate the faulty service that refers to svchost.exe. Well, if it’s something outside of Windows – for example, a program for setting up a sound card. In any case, look for (with the help of Google, Yandex) the root of the problem with regard to this particular buggy service. It does not matter what it is: a DHCP server or a video driver. For some reason, the OS can not correctly process requests for this service, overloading the processor.
