Windows 10: High CPU usage: (peaks)

I first posted in another person’s thread, but have been advised to post my own, so here goes with my problem.

High CPU usage: (peaks).

I only notice it early mornings after switching computer on for the day, because I listen to music over Jango Radio then, and the sound gets totally distorted - I haven’t really noticed it at other times (but?).

Through Task Manager I saw that some background use was peaking right up into the 90+ %, but couldn’t find out what.

Today I got a bit of help after downloading Sysinternals Process Explorer

I won’t pretend I understand anything of this software – way above and far out of my league – but it does have a graph part that shows the peaks and tells you what, so:

Main culprit: taskhostw.exe (peaking in CPU at as much as 97/98 %)
in Process Explorer there usually follows some number after (maybe designating what is using it?), like: taskhostw.exe9596 or 4640/12112/10024/8480/9160/9068/10116

at times it is a group of culprits one after the other (briefly), like:
taskhostw.exe (97%)/interrupts (94%)/procexp64.exe (%? But high)/ skypehost.exe1592 or 9236 (63,90% or 84%)/ svchost.exe9884/1032/8480

skypehost.exe : On a website I read about skypehost.exe, that in W10, the app in Store causes Background peaking, while the Desktop version of Skype does not. I use the desktop version. But I have (hopefully) now uninstalled the Store version (there were two versions installed on my computer), and hope this is one problem less?

That leaves:

taskhostw.exe (main offender)
interrupts
procexp64.exe
svchost.exe (1032/8480)
WmiPrvSE.exe (12488)
Tiworker.exe(11880)

Afternoon: I have now been listening to music over Jango Radio for the last 45 minutes or more without any sound distortion.

This would/might suggest that the high peaks in the morning are connected to updates (and such like) searches, or?

This is all I can say on the subject – totally freaked out with such stuff – way out of my capabilities.

(I also downloaded Securities Task Manager and ran that, but could not see anything that might be causing a problem.)

[RESOLVED] Windows 10: Volume Control Triggers Screen To Flash and Speakers To Beep (BUG)

Hmm, interesting. There is a mild CPU spike when the screen blanks and the beep sounds (only about 25% usage, although that 25% spike shows on every one of my 4 CPU cores). I definitely get higher peaks and plateaus in app initializations and gaming
than I do with this. The process that peaks is the Client Server Runtime Process (csrss.exe) at about 15% CPU usage.

 

System and Compressed memory frequently runs at 100% Disk usage

I think this is the only post someone got a comment this might be caused by the antivirus.

Also other possibilities to try:

Disk usage always at 100% - [Solved] - Windows 10

Did all the suggestions, replaced my Avast-free with Avira-free antivirus, disabled superfetch and windows tips. Checked the possibility with defining the virtual memory, but it works much better when leaving it as automatically set by windows.

Just checked the results by trying to peak my memory usage (what uncovered the problem with the system and compressed memory in the first place) and this seems to work very well. If before the peak to 100% HD use and memory peak got my computer stuck for
minutes, now i can see the peaks, but it falls back after a second or two, and the computer runs smoothly.

Hope it will help others.

Hello, I'll comment briefly on taskhostw.exe - and start by saying there's nothing easy or simple to say that I can find! Because it's little known, internet references often assume the person means taskhost.exe.

First, this exists only in the WinSXS folder (Windows Side by Side Component store).
Ref.
WinSxS Folder in Windows 10/8/7 explained
(Note the cleanup command).

As such it's a bit of a puzzle to me as to why it would be executing.

Second, it's a little-known process, relatively new:

Okay, lets discuss how to get rid of these processes... - Page 2 - Windows 10 - MSFN
I just learned more about taskhostw.exe today. It is the new task host process (surprise!) for several user-mode tasks that used to run inside of separate taskeng.exe processes under Windows 7 and 8. I love it when Microsoft innovates like this. Here, they were attempting to reduce the number of processes running in the background by consolidating two or three taskeng.exe processes into a single taskhostw.exe process.
Process Explorer and Process Hacker both don't know how to enumerate the tasks it's hosting, so I found out the following by trial and error (watching its CPU usage while I started and stopped running tasks helped point me in the right direction). On my computer, it is hosting the following tasks:

• Multimedia\SystemSoundsService (redirected emulator for the PC Beep function; never missed it being off, although I do miss the physical PC speaker on PCs, and the old beep.sys that would make the PC speaker on existing PCs still function. Was very useful for alarms when the speakers were off, headphones plugged in, or the volume muted).
• TextServicesFramework\MsCtfMonitor (not sure that it does anything on a single-language system; I've never missed it being off).
• Wininet\CacheTask (never missed it being off; but I use Firefox for my web browsing and it uses its own web and DNS cache mechanisms).

If you stop all those tasks, taskhostw.exe will exit. Now I'm not sure what ubpm.dll has to do with taskhostw.exe anymore, except that we know that it has its name and that mysterious GUID embedded inside.

TiWorker is the trustedinstaller which installs updates and enables Windows features.
So that suggests some sort of update is going on.
You might like to look at your windows update history and see if an update is being repeated or failing.

 

Thanks a lot dalchina, really appreciate your time and help,

Checked out the Links you gave – a bit too technical for me.

But I did do the disk cleanup


As far as I can tell the problem seems to only happen for a period after starting computer for the day, so I guess I will just have to wait until whatever goes on during that time to finish – or just put up with the horrible (but brief) sound interruptions for as long as it takes.

I will keep my eye open for:

Multimedia\SystemSoundsService

TextServicesFramework\MsCtfMonitor

Wininet\CacheTask

And if I see them running during this time will shut them down and sees if this helps.

(I do wonder if the Multimedia\SystemSoundsService has anything to do with my listening to the Online Jango radio??)



Once again, my thanks, will update if anything good happens
