Hey guys-

I know this question has been asked for other Windows OS's, but none of their fixes apply on Windows 8.

When I log in, everything is fine, everything is very smooth and even faster than when I used Windows 7, but after a few minutes my CPU becomes locked at ~99%, mostly because of svchost.

As it appears on Task Manager, the process is Service Host (No Impersonation). The sub-processes are Function Discovery Resource Publication, SSDP Recovery, Time Broker, and UPnP Device Host. I tried several fixes that worked in XP or 7, but they either can't be used in 8 or detect nothing is wrong.

This is the only thing that makes me dislike 8 so far, a fix would be fantastic.

Make a xperf trace to see the cause. Install the WPT (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt-en-us.aspx), open a CMD prompt with admin rights and type this:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d highCPUUsage.etl

Make a xperf trace to see the cause. Install the WPT (http://social.technet.microsoft.com/wiki/contents/articles/4847.install-the-windows-performance-toolkit-wpt-en-us.aspx), open a CMD prompt with admin rights and type this:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 512 -FileMode Circular && timeout -1 && xperf -d highCPUUsage.etl

after you captured 30s of the cpu usage, go back to CMD prompt and press a key to stop the logging. Now compress the highCPUUsage.etl as 7z (LZMA2, ULTRA) to reduce the size. Upload this file to your SkyDrive or Dropbox and post a link here.

If you have upgraded from Windows 8.1 and you have a high CPU usage that you can't detect in Process Explorer like shown here:





you have an issue with a scheduled task. Look at the green "sdclt.exe". This means the sdclt.exe is started very often. This causes the CPU usage.

You can see this best in ProcessMonitor:





The solution is to disable this task in the task scheduler:

Also phone the Support and open a case so that MS can fix this issue.

Thanks bro. Here's the link.

https://www.dropbox.com/s/35j5n3j12obc5m1/highCPUUsage.7z

If that isn't 30 seconds, sorry, I counted the time and press Enter to stop the process, but it didn't say it was done until like 2 minutes later.

The uPNP service causes the high CPU usage while waiting for compatible devices:

disable the service and try again.

Hi Andre,

I have seen this post and I have exactly the same problem as Leon Of Blades.

Can you help ?

Do you want my highCPUusage.etl ?

Thaks you so much.

Ato.

Thx :)

avast (aswSnx.sys) is doing some wired things. Remove it and see if this fixes it. Also, how many free RAM do you have at the time you get the high CPU usage?

Ok il will remove Avast.

My RAM is ok. When my CPU is at 100% i have about 6go of Free RAM.

I have noticed that this problem arrive when i was in my browser in the internet...

Hi Andre,

I'm having same problem than all, I have a Sony Vaio with 12gb of memory and I'm getting low memory even when I'm only with Excel open.

I can't put a link here because they still need to check my account.

I put a dropbox link on my profile, please check it

I just disabled SSDP Discovery and UPnP Device Host services, after reboot I still have svchost.exe memory usage increasing. is it possible that I have a virus infection causing it? if yes, how do I clean it? I use to have Avast now I'm using Avira, but none of then found something

in your case the cause is the "Software Protection" service which checks if your system is genuine.

The svchost.exe usage is smaller and comes from the Firewall service (FirewallAPI.DLL!FwEnumRules). How much Rules do you have defined?

looks like the driver PktIcpt.sys (WFP PktInterceptor (Pkt Filter)) from GDAta is the cause:

Look if you can disable this functionality.

here's my file also

thanks in advance!

the trace is too short to see anything useful. Capture at least 60 seconds.

the only CPU usage I can see is from the driver ex64.sys which causes some Kernel/SYSTEM CPU Usage. This driver comes from Symantec. Look if there is an update. You use version 20121.3.0.76.

which issue do you have? I only see some CPU usage caused by chrome.exe (green).

the small cpu usgae (orange) by the service host exe comes from the Windows Account/LiveID service. which reads it configuration data.

Watch this video on how to use it:

Hi Andre,

Cheers for the video.

I think I may have jumped in with a slightly different issue. My CPU is fine but my memory has just recently started going to 99%. The taskmanager doesn't show any applications with using anywhere near enough memory to make up the 99%. I have 12GB of RAM so it really shouldn't be happening. I ran RAMMap and it seemed to show a huge amount of memory being taken up by the Nonpaged pool. No idea how to investigate it further though. Any ideas?

The only thing you can do is to update the Atheros network driver from 10.0.0.216 to 10.0.0.234

http://www.atheros.cz/atheros-wireless-download.php?chipset=60&system=7

The other thing I can see is some ACPI.sys calls from accelerometer.sys (HP Mobile Data Protection Sensor). So update or remove this HP tool from your HP ProBook 4540s.

Memory usually goes up to 1.3Gb Ram without doing anything. most of them because of Service Host: Local Service(15,8, (network Restricted 7,8), No network,....) Disk also get up to 99-100%. when i look into Task manager and sort Disk to see which cause my disk goes to high. i see the " Antimalware Service Executable and Service Host: local system (network Restricted) (9).\

Thank you 

what you see is superfetch. But superfetch doesn't impact you:

http://technet.microsoft.com/en-us/magazine/2007.03.vistakernel.aspx

because it runs at low IO priority.

sorry for hijack this thread, I am not on Win 8, i am on Windows server 2008 r2, i see svchost.exe(NetworkService) high CPU usage. With Windows Explorer, i can find that it is threads for WinRM service in this process that actually consumes the CPU, i tried to restart Windows Remote Management service in services.msc but failed. I don't know what will cause if i kill the WinRM threads, so i just suspend them first. Then, CPU usage is normal. However, i still cannot restart the service in services.msc. Then, i killed these threads, and i can restart the Windows Remote Management service.

Hi Andre,

I am also facing the high CPU utilization problem by svchost.exe

I have captured the xperf in file as stated by you. Here is the link to my file: hxxps://skydrive.live.com/redir?resid=FD5AB1C19B004C7D!403&authkey=!AMiinJN7N-AzGPk

Can you please check what is issue with my system? My system is Sony VAIO core i5 3rd gen, 4GB RAM.

Hi Andre,

I am also facing the high CPU utilization problem by svchost.exe

NO, you have a virus/malware with the name svhost.exe (without c) which uses your CPU to do some calculations.

C:\Users\Pushkar\AppData\Roaming\data\svhost.exe -o http://pool.darkcarder.com:8332 -O albert1408.22:80uhkaw3cwn2pg63nz

Thanks Andre!

I am surprised how it got into my system when the Windows Defender is updated!!!

Guess I need a good anti-virus programme now... I thought Microsoft had done good job by providing anti-virus & anti-malware functionality in Defender, but it seems otherwise now :(

Can you please check mine - just started having this issue as well?

https://dl.dropboxusercontent.com/u/24659606/highCPUUsage.etl

Thank you.

Not sure my previous post made it - I am having the same issues - here is my link to file:

https://dl.dropboxusercontent.com/u/24659606/highCPUUsage.etl

Thank you.

You have 2 issues.

1st: the DHCP client tries to renew the TCP config and this causes CPUusage:

(dhcpcore.dll!DhcpRenewThread/dhcpcore.dll!SendDhcpRequest)

2nd: Writing a firewall rule causes cpu usage (mpssvc.dll!RPC_FWIndicatePortInUse, mpssvc.dll!CDfwEngWriter::GenerateFwRule)

Dear Andre,

I have the same problem and I try to run the xperf... But I get the error: buffersize cannot contain 4 argument(s). Can you help me?

Yeah, I tried it again and it worked fine. Must have hit an accidental space or something. However, as you might guess I also have the slowing down problem. Would you be so kind to look at my .etl? Here's the link: hxxp://www.dropbox.com/s/95d1l4ozrbkan3x/highCPUUsage.7z

I run Windows 8 Pro 64 bit (6.2, build 9200) on a HP Touchsmart tm2 NoteBook PC with 8 GB RAM and an Intel Core i3 CPU (U 330 @ 1.20 GHz) processor.

Thanks in advance!

in your case the CPU usage comes from Superfetch service. But I don't recommend you to disable it.

YOu should remove AVG and see if this improves the situation. There are 3 AVG tools which also generate a high CPU usage.

Windows 8 already includes Windows Defender. If this is enough for you, you can use it.

I personally use NOD32.

Thanks for the answer.

How can stop this? I mean prevent using my cpu surly without stoping my firewall.

I am using ESET SMART SECURITY 6

Run RAMMap to see what is causing the Memory usage:

Hi, and now probably some bigger mystery:

Its always taskhost that starts eating my CPU, and stack always hangs in DllRegisterServer. Only restart helps when this happens. Xperf file:

Hi, and now probably some bigger mystery:

Thanks in advance for any help!

the trace is too short. Run it for at least 30s not 1.5s like you did.

this is confusing. Taskhost.exe itself only causes the usage. There is no real callstack.

The only thing I can see is that the nvinitx.dll is loaded into this process. You use the nVIDIA driver 320.49. Try the latest beta and look if this fixes it:

Hi Andre,

Hey guys-

I know this question has been asked for other Windows OS's, but none of their fixes apply on Windows 8.

When I log in, everything is fine, everything is very smooth and even faster than when I used Windows 7, but after a few minutes my CPU becomes locked at ~99%, mostly because of svchost.

As it appears on Task Manager, the process is Service Host (No Impersonation). The sub-processes are Function Discovery Resource Publication, SSDP Recovery, Time Broker, and UPnP Device Host. I tried several fixes that worked in XP or 7, but they either can't be used in 8 or detect nothing is wrong.

This is the only thing that makes me dislike 8 so far, a fix would be fantastic.

hey im having the exact same problem as well

https://www.dropbox.com/s/hi15cyfb9wgta93/highCPUUsage.zip

here is the Xperf scan i did if you can take a look at it 

Thank you, CP

I don't know if people are still having this issue, but this is what I do when something like this happens:

1.) I go into task manager to locate the CPU hog, then trace it to Services, after locating the services causing the CPU overuse, I reset them. I don't recommend stopping anything, just restart it and see what happens. (This may take a short while to have an effect, or you will need to repeat this a few times.)

2.) The other fix that seems to work for me is to simply restart my Win8 PC.

These sort of problems usually happen to me when I put my PC on Standby or Hibernate (like Time Broker for instance). I'm not sure why this happens (this topic for another forum)...

Like I said, this is what happens to me. This may not be the same with other people, but I'd thought I'd share anyways.

Run this DISM command to fix corrupted Windows files:

Andre, please help me. 25% of my CPU is being hogged by svchost at any moment making PC slower than before updating. Been searching for clues for days without result.

How did you find it out? Is there any instruction on how to look at the the problem?

It would be useful for me to know how to check the problem.

I only see timeout.exe uses a lot of cpu time.

you have the same issue like the other users. The sdclt.exe is started and closed every second. Also disable the WindowsBackup notification task.

Hi - I am guessing I am also another victim of sdclt.exe but I cannot pinpoint it. Task manager claims 100% cpu usage while Process Explorer does not say so. Here is the upload:

https://drive.google.com/file/d/0B8hsSnAbb6DtRVNLbGJ3X1FUNmM/edit?usp=sharing

Thank you!

Hi - I am guessing I am also another victim of sdclt.exe

yes, you're also such a victim. Disable the task in the task scheduler.

the svchost.exe usage comes from the APp Experience service (required for UAC)

Thank you for confirming, but I am no sure which task exactly is causing this. 

I looked at Microsoft\Windows\"Application Experience", there are 3 jobs, none of them seem to have an action item that's relevant.

Same is true for 'WindowsBackup'

Application Experience Service was set to manual and stopping it for testing did not help. Looking at Process Explorer data does not provide useful info either.

I see a lot of these processes created and destroyed, yes, but I also see taskhostex.exe taking up the much of CPU. Is it b/c it's constantly creating and destroying these? 

I am having a similar problem. Can you please look into it?

Dear Andre, please help!

I upgraded Windows 8 to Windows 8.1 Pro and after install my HP6720s laptop is experiencing high CPU usage, heating and fan continuously working. I noticed in Task Manager that "Windows host process (rundll32)" is responsible for that situation, but I couldn`t figure why? After I kill that process in Task Manager (in order to test), fan immediately slows down, but after few minutes starts to work hard again, but not for so long as before killing rundll32 process. I`m stuck at this point, I couldn`t find right solution on the Internet, although I `ve seen a lot of people having problem with high CPU usage and processor heating on different laptops after transition from Windows 8 to Windows 8.1.....

Here is my etl file: https://dl.dropboxusercontent.com/u/24530567/highCPUUsage.zip

open task scheduler and disable the notification task:

yes, eventualy i did that. I removed the hdd, put it on another laptop as secondary dryve, took ownership of sdclt.exe and renamed it. Now everything is normal. Will this somehow affect the normal operation of windows?

Was it a virus?

Anyway, thank you for your help in this matter.

OK, I've been after the same issue for 2 weeks already, Windows 7 x64 Home Premium.

The culprit again was UPnP Device Host and as I need this service operational, I just couldn't disable it. So in my case I have a wireless network adapter, that is shared with my on-board wired LAN adapter. At the same time the wired adapter is disabled.

After removing the Internet connection sharing, svchost.exe stopped using 80%+ of CPU.

Thank you so much for all your help in this thread over the past several months. If you have time, could you please review my ETL log file?

the small cpu usage comes from coreServiceShell.exe and YCMMirage.exe.

To see the RAM usage, too you must run this command:

xperf -on latency+ReferenceSet -stackwalk profile+VirtualAlloc+VirtualFree -buffersize 1024 -MaxFile 1024 -FileMode Circular && timeout -1 && xperf -d HighCPUUsageWithVAlloc.etl

I have the same problem (high cpu usage) since few days .. with windows 8.1.

you have no real CPU usage, the high cpu usgae comes from the sdclt.exe which is started over and over again.

Disable the confignotification task in the task scheduler.

Thanks a lot .. everything is ok now !

The trace shows some CPU usgae spikes by a tool called (fnfdeiocg.exe) which uses OpenCL (igdfcl32.dll). I think this is a malware (based on the file location: C:\Users\Iulian\AppData\Local\Temp\pjruprzcodwy\fnfdeiocg.exe -c "C:\Users\Iulian\AppData\Local\Temp\pjruprzcodwy\cfgb").

Looks like this tool uses your hardware for some calculations. Boot into safe mode, run AutoRuns, cleanup the tools and do a virus scan.

Hi Andre,

I am also having the issue with svchost.exe using a lot of CPU. I wasn't able to figure out what the problem is. Can you help me? my highCPUUsage.etl is located on SkyDrive here: http://sdrv.ms/17Uek40

Thank you.

in your case it is WindowsUpdate which checks for updates.

Could you check out my file too?

Hi Andre,

I have a similar problem and i can't get your instructions at the top of this thread to work using the cmd prompt.

I have usage issues. I am using w8.1

Also see the cmd prompt shot.

I can't put images into here so have included them in a dropbox file; https://www.dropbox.com/s/5j42wqgzgup8sb4/CPU%20Usages%20issues.pdf

Please can you help

Andre

Sorry for the confusion.  I forgot to copy the file up.  Here is a new link - https://www.dropbox.com/s/52ikztzn3jseya6/highCPUUsage.zip  I have noticed that my Microsoft bluetooth keyboard and mouse have issues during these times of high utilization as well.  I thought it was just when the CPU reached 100%, but I am having the issue right now and the processor only shows about 60%.  I am running 8.1 on an original Surface Pro.

Thanks Andre.

Thank you for your help.  I got a little over anxious and deleted the whole "Windows Backup" folder out of the task scheduler and rebooted and the issue did not come immediately back as it has before.  I suspect this has taken care of the issue and I hope it has not caused any ill effects.  Since I am working on a Surface Pro I do not know of an option to remove the hard drive and rename the file mentioned above through accessit from another computer.

Again thank you for your help. 

Could you have a look at my file too. ;-)

Much appreciated.

the DNS client services loads the Host file into the RAM and this causes the periodic svchost.exe usage:

The host file was full with lines excluding ads websites (genrated by spybot). No need for that anymore when using Adblocker in Chrome.

Thanks for the tip Andre !!

Hi, 

Can you help me  with the same problem?  CPU is using 99%.

Hello,

I see that you are helping people with this type of problem. Any chance you can look at my etl file and let me know what is causing the high CPU usage? My laptop was running fine then all of the sudden it started lagging and using 98% of the CPU. I appreciate your help!

Thanks!

Hi! I'm sorry to bother you. I'm having the same problem. If you can help me, that would be wonderful. 

Sorry to bother.

My file is here. https://dl.dropboxusercontent.com/u/61139479/highCPUUsage.zip

hey,

Also having the same issue, not as familiar with the files you need to see and would appreciate any help I can get. Email me @ Dragonfirestar99@gmail.com

Hello Andre,

Could I please get help also.  I have uploaded my file.   Windows 8.1 - 100 percent used by svchost with no user programs running, just startups.

Andre,

I've got another one for you. I installed a network card that wasn't compatible with Win8 and now my cpu and audio/video is going nuts. I've removed that card but I'm still having issues. Here is my file. Thanks

https://dl.dropboxusercontent.com/u/72507910/highCPUUsage.7z

Andre,

Could you take a look at this one too? I've tried to do a complete 8.1 reinstall but I'm still having the issue. Thanks

https://dl.dropboxusercontent.com/u/72507910/highCPUUsage.7z

Hi Andre,

I have the same problem too and I need your help. Can you tell me what should files should I provide you to help to solve this problem? How do I get them?

Thank you.

Hi Andre,

Please could you assist to analyse my etl file. Link is below.

100% CPU started yesterday. Most probable connection I can think of - I installed some Office patches that showed available. 

Sorry - might have been bit longer than 30sec as prompt screen wasn't initially responsive. Compressed file is 11MB.

https://www.dropbox.com/s/dcfy69zi5mhsx9q/highCPUUsage.7z

Many thanks.

I've made the "highCPUUsage.etl" but I can't seem to find it in my 7-zip File Manager. The only etl file I've found at all is labeled "kernel.etl" and it's found right in the local disk C:\ page. I've searched for it with my File Explorer and found it and it's listed as under C:\Windows\System32\ in there but when I open up to that file on my 7-zip File Manager it's not there. Should I just put the 43mb one in dropbox and post that link?

Hi Andre.Ziegler

could you check my problem please?

here is a file with the xperf trace to see the cause:

https://www.dropbox.com/s/0c71x294w7bhyit/highCPUUsage.zip

and here is a image with the process explorer showing the issue

https://www.dropbox.com/s/ua9ayhwi44fa4kn/procces%20explorer.png

here is my link and thanks in advance

Hello, Andre!

This is a link to my xperf file, hope you can help me out with this. If it's in any way helpful, I get the high CPU spikes while streaming using a program called OBS (Open Broadcaster Software). However, it's not OBS that causes the spikes, it sits at a constant 27~32% CPU usage.

Thanks in advance, much appreciated!

Have a good day!

Hi Andre,

Can you check my file as well?
