Windows 10: Service Host: Local System (2) using between 12 and 35% of CPU time

Not unique. Here's an appallingly formatted post- same thing, no solution:
Update Orchestrator Service run amok - Microsoft Community

Note DISM does not help.

** You could try setting the service to manual
Windows key + R, services.msc

Info:
Orchestrator1

Note it has to be started by sthg & is essential for updates.
Update Orchestrator Service (UsoSvc) Defaults in Windows 10

 

Acutally it's extremely weird but it went off on it's own... Maybe it was just in normal/usual activity...

Will mark this post as solved as soon as I feel like this issue is mostly fixed. If it's just in high activity for a minute or 2 it's fine I think ..

This stuff all started after I forced the creator's update with this Download Windows 10

Anyways thanks for helping me out.

 

Ok.. hope it works out for you.

 

Definitely not fixed... I tried this "Update Orchestrator Service (UsoSvc) Defaults in Windows 10" but didn't do anything.

Let me know if you have anything else up your sleeve

 

So far that's the only clue- however, it may be that simply disabled the service, which wouldn't take you any further. However, something triggers the service and causes it to run.

Based on that, you could try a cut down version of a clean boot - don't disable services, only start-ups.
Then disable services other than MS services.



Note: Update Orchestrator is listed, and use the hide MS services option.

Note it's stopped - as I said, it would seem something is triggering yours.

Note the triggers in task scheduler:

USOclient.exe randomly popped up on computer recently upgraded from 7 - Windows 10 Forums

 

I don't know if any of this could help to bring clarity:









I've just deleted a whole bunch of programs and stuff I considered useless and just updated my Intel drivers, but nothing changed.

I wouldn't be surprised if this would be because of a defect driver. I don't know which one though. Do you think I should try to update them some way?

I was also thinking of maybe disabling all of windows update and only updating manually once a week or something... Would you consider doing that if nothing else helps?

 

Here's the overview of my task settings:




It seems to run astonishingly frequently, but I'm quite unaware of it:




You could set updates to notify only, which is how I have them set. That means that together with Defer Feature Updates + a delay of 180 days, I have a lot of control - and never an unexpected restart.

or for convenience via Winaero's great free tweaker - with full explanation for each.

 

Hello after a long time,

I have tried to disable windows updates by trying Option 1, however I only have windows home edition so that didn't work out.

Tried the Winaero tweaker and didn't work either, it's still going crazy.

I'm starting to feel as if reinstalling windows would be my best bet at this point.

what do you think?

 

Hi, option 2 of the same tutorial does the same using a reg file. However, you don't want to live with Windows updates disabled.

I can't recall if you've tried creating another user for test purposes- if that user account works, it's some configuration issue in your current user account, rather than Windows.

Note that the next new major build is coming out in October, but that's rather a long time to wait.

If the new user idea doesn't help, you could try an in-place upgrade repair install which keeps all programs and data - you basically use the base iso (build .0) of your current build - Creator's if Creator's etc- and when booted normally, run setup.exe. You can mount the iso or create a bootable medium and use that - which is what I prefer to do.

Otherwise, make sure you have a full backup and clean install.

The key to almost always having a second chance to recover from difficult situations is to routinely use disk imaging - a 3rd party program such as Macrium reflect (free). You can then recover your PC/disk/partition/Windows to a previously working state without technical help. Any data on the recovered disk would of course be that as of the date the image was created- that's why I keep my personal data off C:.

 

Hello again,

It's been a long time since, but as you mentioned the October major build did indeed fix it.

It's wonderful I don't need to worry about that issue anymore *Party

thanks once again for the help and hopefully it never comes back again *Biggrin

 

Glad that worked out for you...
