Windows 10: Brand new Win 10 computer runs slow after setup

Hey Cortana is apparently built in to Win 10 and cannot be disabled, only hidden.

In answer to your 4 points above:
1) As near as I can tell Windows now seems at normal speed. Browsing is still a bit slow and I occasionally get "Firefox is not responding" messages.

2) Restarts now seem to be normal speed.

3 & 4) 5 minutes after restart Task manager Performance graph now steadies at 13% at idle. After about 15-30 minutes it rises to 30%, but if I move the mouse, it returns immediately to 13%. Clicking on any icon causes a brief spike to between 30 and 100%.

There seems to be considerable improvement, but this problem has been so slippery and changeable I wouldn't be surprised if it worsened again. Part of what I did before CPU dropped from 60% to 13% was to remove a number of programs I would like to have. At the end of this work I will add them one at a time several days apart keeping careful notes and restore points as you instructed. If they cause CPU to rise I will regrettably remove them again, but this would sacrificing features for speed which is still a problem.

If you have any further suggestions I would be happy to hear them, but I don't want to waste your time working on what may not be a significant problem. Perhaps we should just wait for a week or two while the computer is in use and see what develops.

 

Hi, As regards your CPU use and top process my point here is simple. Turn that off as shown in the screenshot (it's nothing to do with

whatsoever. It' s simply turning Hey Cortana off so Cortana does not respond to your voice.

That should mean cpu use due to Windows Audio Device Graph Isolation is much reduced.

 

Sorry, I accidentally sent the same post twice.

Thanks for setting me straight on Hey Cortana. Turning it off dropped CPU Performance to 5% and audiodg.exe to a steady 0% in Normal start mode!

Following is groups of screenshots after 3 types of start: ("right after previous" means after the work of taking a screenshot, pasting it in Paint, and saving it)

NORMAL START
idle 10 minutes after start

opened firefox


idled 15 min with Firefox open

right after previous



CLEAN BOOT
idle 10 min after start

right after previous


idle 20 min

idle 2 hours



SAFE MODE

idle 20 min and move mouse

 

Hi, Good. Idle use is fine.

3rd screenshot- seems to take a long time to open firefox- mine doesn't even peak at 100% CPU.
Note the internet use- try starting FF with a blank home page. I think that would let it start faster.
(Naturally it's your choice what you use for your home page)

4th screenshot- CPU use 50% with no other activity, FF open? That's odd.
Suggest you investigate with Resource Monitor and task manager, Process, Details..
- what specific processes are using CPU time?

Also try starting FF in its Safe Mode (no addons). Compare startup time and CPU use.

6th screenshot - 20-30% CPU use after clean boot - that's odd
- again investigate with Resource Monitor and task manager, Process, Details.
- what specific processes are using CPU time?

 

In my opinion, per your computer specs I think you've pretty much trimmed down Windows 10's resource usage to the best without compromising functionality and with that most of your resources should be spent for the programs. In my case I have so many programs running on startup, but I do need all of them running so I can use most of the features available

 

I ran the tests in your post #17 before I read your post #18. If #18 means that you think there is nothing more you can do I would certainly accept that, and be grateful for all your help, as I'm about ready to give up re-install Win 10 and start all over.

Since I have already done the tests in post #17, I will include them below in case you want to look at them. Also a new symptom has turned up, which is part of what inclines me to give up: msconfig is stuck on selective startup. Every time I restart, whether in Normal, Clean, or Safe mode; after restart if I go immediately to msconfig, Selective Startup is pre-selected. If I select Normal Startup and restart, the same thing happens, so I guess now I can never be sure whether I am in Normal or Selective startup.
--------------------------------------------------------------------------------------
Tests from post #17:
NORMAL BOOT
normal start, Firefox open, idle

normal start ,idle, details



normal start ,Firefox in it's safe mode

same thing, later



normal start, Firefox restarted in it's safe mode



CLEAN BOOT

clean boot, nothing open, idle 10 minutes



in clean boot, CPU performance varies a lot:
processes during High CPU


processes during Low CPU




details during high CPU

details during low CPU


-------------------------------------------------------------------------------------------
The performance graph you posted of your system looks just like what I see on my other very similar model computer with Win 10, and on my old Win 7 computer. I've never seen anything during idle like the image "clean boot nothing open idle 10 minutes" above.

Thank you for your help.

 

You could try using a restore point.

clean boot, nothing open, idle 10 minutes
- what's missing is which processes are responsible.
- disk usage is 100% too.

I'd not wish to guess what might be doing that..

Given what you installed and ran (post 1) it's not clear what may have happened.

Do check your disk (download install and run Hard Disk Sentinel (trial) ) and post a screenshot of its GUI.
This is worth doing to be confident.

Of course you can run
chkdsk c: /F
from an admin command prompt
and
sfc /scannow

or do an in-place upgrade repair install
but I'm not confident that would help.

If you elect to do a clean install, what I recommend is
a. you install Win 10 only, and test it for a while.
b. If ok install e.g. Macrium Reflect (free) and create a base image. (Option Backup, Backup Windows)
c. Update Windows.
d. If ok, create a differential image
e. Install e.g. 5 of your commonly used progs, checking each time.
f. If ok, create a differential image
g. Install more progs and If ok, create a differential image
h. Repeat e. until a problem occurs or complete.
Maintain a simple log of changes and images

Continue to routinely use disk imaging. That way you (almost) always have a second chance.

 

OK, I will do the items in your last post short of a re-install.

Regarding "- what's missing is which processes are responsible": the 4 screenshots after "clean boot, nothing open, idle 10 minutes" show Task manager Details and Processes under the same setup: clean boot, idle except for Task Manager. I included two of each because CPU usage varies extremely.

It just occurred to me that some back story might be helpful. The computer we have been dealing with here is my wife's new computer. We are replacing her old Win 10 computer because it has slowed down to almost unusable. In April I was using her old computer to set up Roku on our smart tv. In the process Roku customer remote assistance ran a command prompt program on her old computer that they said showed the presence of Alureon trojan. (She uses poor passwords and browsing behavior). Alureon was part of the reason for replacing the old computer. During my original setup on the new computer I started noticing problems as I mentioned in my first post. The problem seemed to improve, and I completed setup without inserting ANY media. Then I moved files from old to new computer. I researched how to safely do so as I did not want to transfer Alureon. I do not recall exactly what I did to transfer files. I am sure I limited the number of files transferred to about 30% of what was on old computer and used only new unused media that had never been in another computer. Sources recommended CD as more secure than flash drive, so I used CDs. I am sure I ran a virus scan on the files to be transferred, I don't recall whether it was in new, old, or both computers. I am sure the problem started before transferring any files, and afterwards it was the same or possibly worse.

 

windows defender is supposed to be able to remove alureon: Trojan*BiggrinOS/Alureon.A
Run windows defender as full scan.
When it has completed run windows defender in the advance section with offline scan.
It will reboot, load windows defender, and run a quick scan.
Would follow dalchina's suggestion with clean install so that you have a base to start from.

 

I have 2 restore points, both failed. Msconfig is still stuck on selective.

Hard Disk Sentinel results were "perfect".

chkdsk c: /F failed to run with computer on as "the volumn is in use by another process" even though nothing was open.

sfc /scannow result: "Windows Resource Protection did not find any integrity violations".

Unless either of you have a better idea, tomorrow I will run Windows Defender, followed in-place upgrade repair install. If that fails, I will clean install.

Thank you both for your help.

 

Noting you have the anniversary edition:

80070091?

Well known error- there's a fix. Huge thread on this forum, about the 2nd post I think. Can be found by searching for the error number.

chkdsk c: /F failed to run with computer on as "the volumn is in use by another process" even though nothing was open.
- that runs after a restart.

From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Post back the result, which you can get after a restart as follows:

or
How to read Event Viewer log for Chkdsk in Windows 10 [Tip] | Reviews, news, tips, and tricks | dotTechdotTech
or
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!
Make sure the result is clear or fixed- else do not proceed.


Note that to do an in-place upgrade of the anniversary build you will need to use an iso/DVD/USB disk you already have, or download one for that particular build. MS's media creation tool will give you the Creator's build.

 

Hi,
I wouldn't expect much from a 1.6Ghz dual core processor.
If you want performance get a quad core in the 2.50+ range next time
All browsers will stall a dual core to a crawl when opening them
Browsers are getting more power hungry not less it is the price for speed *Smile

 

Dalchina:
I read a few of the posts under the search for 80070091. They seem to be a general discussion of aspects of many ways to repair system restore. I can't tell what to actually do. Can you give me instructions?


Thanks for the instructions to produce chkdsk results, they are below.

That's not true in my experience. I never experienced any freezes nor 100% CPU usage with my dual core laptop with Internet Explorer 11. My former 2.2 GHz quad core laptop is infact slower than my current 2.5 GHz dual core laptop when it comes to web browsing.

 

System Restore fails: AppxStaging %ProgramFiles%\WindowsApp 0x80070091 - Page 2 - Windows 10 Forums
See #13

I've not had to do this myself - although I started that thread, and someone cleverly found a fix, after a few weeks I happened to try S Restore again and then it worked.

If you upgrade to the Creator's build and apply an update, that problem has been fixed as I understand it.
