Specs: Windows 10
As the title, I'm now encountering this high CPU usage issue on my Windows 10 computer. The process that's hogging my resource is svchost.exe (netsvcs). Not all of the CPU resouce, but around 30% and stuck at that rate for hours.

When I reboot the computer, the issue come back after it boot up.

What I suppose to do to resolve this problem?

I agree entirely with Fingers about security but would add that on Windows 10 Home manual updates is not an option. To do it you have to stop updates semi-permanently, find out what updates there have been (at least once a month), then go and find them. I would not recommend this procedure unless there was a darned good reason.

Always pop back and let us know the outcome - thanks

Best start with some quick malware checks. These three small freebies often find what anti-virus programs miss. Run them in the order given:

AdwCleaner:
https://toolslib.net/downloads/view...
(blue "Download Now" button on right).
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Clean" button.

Junkware Removal Tool (JRT)
https://www.malwarebytes.org/junkwa...
(blue Download button).
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.

MalwareBytes:
https://www.malwarebytes.org/
(use the "Free Download" button rather than the "Buy Now" button).
Install and Run the Threat Scan - quarantine anything it finds.

If anything is found please copy/paste the associated the logs on here. The ADW log is a text file in the ADWCleaner folder directly off the systme drive root (usually C).

Thanks for your suggestions and helping me to find the solution.

I've found that svchost.exe (netsvcs) is only hogging CPU resource when Windows Update is turned on. After disabling it, everything is back to normal.

I've followed a tip in this post, which suggested me to uninstall Windows updates. It seems the problem come from there after I upgrade to a new build of Windows (Windows 10 build 1067).

I've rollback to the previous build and the problem is no longer exist.

OK but Windows might keep foisting the 1067 build on you.

Not really an answer, updates are made for functionality and security. Set your system for manual updates and get in the habit of doing them once a week. If you cannot do this then then go back to automatic or download and remind you to install.

You have to be a little bit crazy to keep you from going insane.
