Service Host: Local System (19) Using 35% CPU (Windows 10)

[FreeWayPineapple]

My CPU is constantly at 35% usage due to a windows process called Service Host: Local System (19). I am not sure how to fix the high CPU usage.

I figured it was just my PC preparing to update, but I have no updates available. At this point, I really don't know what to do.

Edit: I just realized that the (19) means that there are 19 sub processes, but I can't figure out which one is causing the strain on the CPU.

I remember when i had runaway svchost, so I disabled superfetch and windows updater through services and it dropped back down to less than 1%.

I had the same problem and through trial and error found that the issue is either with the User Profile Service, or User Manager. In any case, when I went to Start -> Computer Manager -> Services and Applications -> Services and restarted the User Profile Service, the problem fixed itself. The first time I did it, the problem only went away for a minute or two. The second time, my computer's been working okay for 10 minutes or so. Hopefully Microsoft gets itself together and fixes the underlying issue pronto.

Which version of win 10 are you on?

I ask as they broke the service hosts up in the creators edition so while there might be 19 in the one you have, I have 19 separate with local system in their name and it would be much easier to work out which one is at fault. There are some still in groups but most I have is 4 under a service host

there might be an update your PC doesn't know about. Go to this page and click upgrade now. that will download the upgrade assistant. Run it and it should upgrade win 10 to latest version. Suddenly your service host total was go from about 16 to around 70 but the only real difference is they aren't grouped as much anymore.
