Idle CPU usage ~40% after update to 1803

[vanished]

So I updated my laptop to Windows 10 1803 today from 1709 and ever since then, when I look on the performance tab in task manager, it shows my CPU is about 25 - 40% used, give or take, but when I look in the details tab, nothing wants to take responsibility - the system idle process claims it's 90%+ idle.  90 + 40 =/= 100 so someone is lying, and I know by the fact games that used to run smoothly do not any more as well as the temperature of the body that it's the details tab - something is using this CPU time, even if it won't admit it.

 

I thought it was the indexing service and turned that off, but it's still doing something.  Any ideas?

still updating more than likely. background install or data mining your buttocks..

Try using the Resource Monitor. It will show things that don't show in task manager.

Most likely Windows still being a jerk and doing stuff in the background after the update. Checking for updates, installing updates, running virus scans, indexing, sending all your private information to Microsoft, etc.

you're not going to believe this but it's all fine now.  I swear, I have been fighting this all day, trying different things, rebooting, retesting, etc. and for literally hours, nothing seemed to make a difference.  I finally get around to making a thread, decide "hey I'll just reboot one more time since I know someone's gonna ask that" and sure enough, it's all good now.

 

I guess it does make sense that this was a "me" problem and not a global issue with 1803 or we would all have heard of the angry masses complaining by now

Still very odd...

Uhm @GoodBytes? 

 

@Ryan_Vickers I didn’t have any issues with 1803 that sent me to a fist of rage other than the usual Windows 10 quirks that I’ve hated for years.

This update has been surprisingly painless for my headache of a system.

[vanished]

Apparently I spoke too soon... I had a good run of several uninterrupted minutes with the level of performance I used to have normally but it's gone back to crap with a baseline of at least 25% CPU used all the time.  At this point I feel like it's watching me and toggling the issue on and off just as I report it to troll

As far as I can see it's not updating or installing anything, nor indexing or virus scanning.  I did look in resource monitor but it didn't provide any additional insight

Go to : Settings > System Display > Notifications & actions > Turn OFF "Get tips, tricks and suggestions as you use Windows"

 

Open the registry and edit the following entry ;

 

HKLM\\SYSTEM\CurrentControlSet\Services\TimeBroker

find the key called START and change it's value to 4

 

Restart

Already done, I never have that on

I don't see a "TimeBroker", just "TimeBrokerSvc", and "TokenBroker"

 

Might I ask what that does?  Is it just disabling a service?

TimeBroker (in your case it should be TimeBrokerSvc) is a service that manages the "metro app" running in the background (somehow it's often an issue with Groove music or some other store apps stuck in the background) ... alternatively you could also try another setting ;

 

Settings > Privacy > Background apps

and turn off "Let apps run in the background"

 

But that might not help if the service TimeBroker is the issue ... 

 

 

Stuff I had to diagnose one time or another, I love Windows 10!   ... /s

Hm, well in that case those aren't the instructions I would have given... there's easier ways to disable a service   But thanks for the tip, I've already done it and we'll see how that goes.  Early signs are promising, but they're also too early to carry any weight

Well, since it's a problematic service, sometimes it won't let you disable it from the services console, I have been using the registry edit for a while to turn off different services because of that

Well I did a bit more testing and sadly that has not solved it I think it just seemed better because it was a fresh boot.  It seems to take a little while for the problem to activate.

Damn, if you look at the Performance tab in the Task manager, is one of your drive "Active time" is high but with low read and write speeds?

 

If so then it's most likely a problem with Windows Update, it might be hard to diagnose and short of doing a "reset" of Windows update (not a reset of the machine) it might stay like this for the next days or so.

 

You can look at what a Windows update reset looks like but it's not pretty, I think I have a batch file somewhere that I used once (if you're interested).

No everything else is idling fine (disk, wifi, GPU, etc.) it's just CPU that's higher than it should be, and no matter where I look nothing will take responsibility for it.  I don't know how that's even possible, seems like that is a pretty significant issue all on its own.

[WkdPaul]

It might be a driver issue then ... turn on "Show kernel time" in the Performance tab of the task manager.

 

If the "kernel" line (darker blue) is lower than the CPU usage then it's an application, if the kernel line matches the CPU usage then it's most definitely a driver issue ("kernel time" is only for high privilege access to the hardware).

Yeah I have a general idea what that indicates and the high idle is comprised pretty much entirely of this.  Any suggestions how I might find out the problem one?

Try using Kernrate (it should pull out the name of the driver that is using high kernel access)

I personally never had to use it, so we're both in uncharted territory from now on!

[WkdPaul]

You can also use Process explorer, but sometimes it won't show the culprit that you might be looking for, especially if it's drivers related ;

Wow, blast form the past lol that installer is super 90s

Any idea how to actually use it?  Seems to be a command line tool... I gave it a try but it complains about some error "NtCreateProfile on module kbdhid, source 0 failed c000000d".  At least I think that's an error message.

I remember that from the XP days but isn't helping here.  It disagrees on the total CPU usage and doesn't show and culprits either.

Unfortunately, I'm not sure on how to use it, it was an XP command line tool but apparently it still works in Windows 8 and 10, I can't do any tests with it right now since I'm on my work laptop, I'll try to figure it out later on my dekstop!

Yeah, that's what I thought.

Looking around a bit it seems like it should be easy enough to use: just literally run it and read the output, no special flags needed.  But, as mentioned, it doesn't work for me

[WkdPaul]

Yeah, looking around a bit and it seems it won't work on Windows 8 & 10, I misremember something for sure (I swear I remember someone using it on Windows 8 somehow ... ).

[AlTech]

The only issues that I've had on 1803 are BSODs and Freezes.

 

CPU Usage is all good .
