What is svchost.exe? 

According to Microsoft, svchost.exe is: 

“a generic host process name for services that run from dynamic-link libraries”.

 

In simpler words, it’s a legitimate Windows process when running certain Windows operation. But in certain cases, you may see svchost.exe process hogging the CPU or memory resources in Task Manager without apparent reasons. 

How do I fix it? 

Here are 4 solutions for you to try. You may not need to try them all; just work your way down until you find the one works for you. 

1: Scan your computer for viruses

2: Disable certain svchost.exe services

3: Empty event viewer log

4: Troubleshoot Windows Updates issues 

Step 1: Scan your computer for viruses

High CPU or memory usage of svchost.exe services can be caused by viruses or malicious programs. So run your antivirus program and scan for possible viruses and malicious programs.

If you find any, uninstall them or remove the viruses completely to see if the problem is fixed.

    Thanks a lot!
    It was the “Windows Update” service who was making my pc work too much.

  • Sean Fulop

    This put me on the right track, but some problems are more complicated. In my case, the offending svchost process was Windows Management Instrumentation, which is a process necessary to the system and cannot be stopped permanently or disabled. So then I had to trace down which active software was “monitoring” stuff that was causing this process to run too much. I think it was Malwarebytes, but I am still verifying.
