Win 10 high cpu load,which services to eliminate?

post #1 of 8
Thread Starter 
50% cpu load on my Sony Vaio SR 590 Laptop, it runs hot (62C, clean fan and on a support device with a fan, thermal paste replaced, will get to 81C 9600 core duo at 2.8Ghz, runs cooler on battery alone as clock speed is reduced). I am using Win 10 (it came that way). Task Manager check indicates it is all services. I list them.
Application Information
Background Intelligent Transfer
Computer Browser
Delivery Optimization
Device Setup Manager
Geolocation Service
Internet Connection Sharing
IP Helper-this I can set to manual
Shell Hardware
System Event Notification
Task Scheduler
Themes User Manager
User Profile Service
User Management Instruction
Windows Update

My research shows some negative consequences if I eliminate or stop any of these services. I wonder if setting these services to become active on an "as needed" basis is my answer (is this possible?). I do wonder why they are all running upon startup. I just may go back to Win 7 but who wants to lose the use of a paid for operating system. Thanks

You can use the Resource Monitor to identify the actual service that's eating the CPU.

Hello Bruce. Resource manager took me to servhost.exe. Expanding servhost took me to wuauserv (48% of the load). Researched this and I am told "your system is updating,give it some time" This is an OK answer, something I did not expect. Let's see. +Rep

EDIT: as we see Windows Update is part of the group I initially identified.

EDIT 2: Well it is not updates. One odd thing. Even 50% cpu usage should not send temps this high, with all the extras I have done to reduce temps. I do not like 50% load at idle but many Win 10 users report high cpu load. I try Win 7 and perhaps some modifications so more air flows inside the laptop.

Does it do that between restarts? And I don't mean fastboot restarts, but real system reboots.


Seems like that happened to me a few months ago... Try opening Windows Update, see if it's churning away doing something.

Also, I think that Windows update didn't look like it was actually doing anything when this happened to me.


Try this:

Particularly the "net stop wuauserv" thing.

Hello Bruce. I will try the link provided. Just for information's sake I used a different hdd and loaded Win 7. My temps are fantastically low (not above 38C idle, 52c loaded). My conclusion is that there is nothing wrong with my laptop's air intake design, fan, thermal grease, any kind of dirt problem. This problem is pure and simple a win 10 problem. Now I must decide on if I want to troubleshoot win 10 (I like to figure out problems) or move on and simply use win 7. Thanks again.

Edit: My laptop stayed cool and under 25% load even when doing the big after install initial updates. This laptop came from the Win 7 era, it seems to want to stay there.

Do you use Windows 10's metro apps/cortana? If not Geolocation isn't needed.

I had similar problem to yours on my surface pro 4, try windows key + r, type in services and hit enter, then find Windows Modules Installer and see if the Startup Type is set to manual if it's on automatic and it should help windows update from using cpu when it's not actually updating or anything (when I encountered this problem, I gave it the benefit of the doubt and let it run for 5 hours before changing the settings for services rolleyes.gif)

Doing this doesn't actually interfere when you want to use windows update either
