Service Host (svchost.exe) Using 99% CPU

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
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.

I upgraded to iTunes 10.5 on XP and now it and applemobiledeviceservice.exe use 100% CPU. How do I fix this?

I upgraded to iTunes 10.5 on XP and now it and applemobiledeviceservice.exe use 100% CPU. How do I fix this?

When I called Apple Support to ask about the 100% CPU usage, they wanted to charge me because my Ipod was out of warranty. I insisted on talking to someone and finally got to talk to a software engineer for free. He said that he had never heard of the problem in his three years at Apple. Nonetheless, he sounded really interested and suggested that it might be a conflict with anti-virus software. I deleted the antiviruse and that DID NOT HELP AT ALL.
It seems as if Apple could care less. There is no official response. Their primary response is to look at the Forum. At least you find out that the problem isn't your fault, it really is Apple!!!!
So far the best solution is just to delete iTunes and use Mediamonkey to sync your pod.
Apple, please fix this!!!!!

Svchost.exe using %70ish percent of my CPU. Help!

here is my trace

Hi Skywurd,
When did the issue start to occur ?Will the issue persist ?
Have you checked the services included in the svchost.exe from the task manager ?
The only suspect process is the NvStreamNetworkService.exe,it is a process belonged to Nividia .We can try to update the Nividia driver or reinstall the driver to have a check .
Best regards

SVCHost.exe takes 100% cpu on random occasions

Ok so I have had a rather interesting problem and I don't know for sure if it is related to the sound blaster card in my computer or not.
I have a Sound Blaster Audigy 2ZS. Once in a while, usually later at night an svchost.exe process starts taking up 00% of my cpu. If I kill it and run any programs after killing it that use sound, I get no sound until I restart my PC. Programs that are running while that process takes 00% of my cpu keep their sound even after I kill the process until I close and reopen those programs. These programs consist of things like World of Warcraft, Windows Media Player, VLC Media Player and the like.
I was wondering if anyone has had a similar problem or knows what it might be, and possibly a solution.
Thanks
::edit:: renamed svchost.dll to correct name of svchost.exe. Was confused my bad!Message Edited by jziah86 on 05-4-200702:43 PM

Aware that svchost is not a driver. Aware that it manages the functions of any program that opens and is running on your system. Aware that Creative driver is loaded and problem with an instance of svc.host begins to display and that 00% of system resources are in use. Aware that when that instance of svc.host is ended that the problem is resolved and that the sound card will no longer function. Visitng other forums lead me to the investigate the Creative issue further. It is clear that there is a relationship between the loading of the Audigy sound card driver and the malfunction in the management of memory and system resources at a root level. The claim being made at present is that there is a conflict between the driver and something in a recent XP update from our friends and family at Microsoft. Since this is on one of my home systems, this weekend I will try to rollback to an older driver to see if it makes any difference. I will then try a different sound card to see if the problem persists. If so, I'll simply dump my Audigy card(s) and move onto something else. Hate to do it, but I don't have the time to fix their problem. Any other suggestions - especially from the Creative people who have advised that my card is beyond warranty and I can pay them to try to find a solution. Well, I'll pay for another sound card first! Don't expect them to fix my problems, but to fix their own. Like many buyers I do a lot of research BEFORE I purchase new components. Reviews and user comments mean a lot.

LMS.exe using 25% CPU

Noticed that the LMS.exe on my new T510 is constantly using 25% of the CPU, I assume this is not normal, anyone know what I need to tweak please?
Solved!
Go to Solution.

I don't know why it's constantly using 25% CPU, but i belive the file belong to "Local Manageability Service" (http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-74374). You could try to upgrade to the latest version if not already done so. I'm also under the impression that very few people actually use this so you could uninstall as well and disable in BIOS if you don't need it. I don't have it installed and keep it disabled in BIOS since i don't need it. Like to only install what i need to keep it as simple and clean as possible.

A process java.exe uses 100% cpu

This problem stops me start database 10g on Windows XP. I am wondering anyone might have same experience before and could share how to fix the issue. Here is situation:
Every time when 10g database starts, a process java.exe which is loaded by nmesrvc.exe (I think it is OracleDBConsoleMyInstance, right?) uses 89% cpu forever. Because of this, OEM couldn't work! Shutdowning the database and restarting it didn't solve the problem. Killing nmesrvc.exe can stop the java.exe. SQL*Plus still works. But iSQL*Plus didn't works.
If I stop process OracleDBConsoleMyInstance from Services of Windows, I got error: Error 1053.
What is wrong here. Your help will be appreciated,

I had the same problem and was able to resolve it.
I am using 2 W2K3 servers, one for infrastructure and one for mid-tier (Portal). On the infrastructure machine I used the Administrative Tools -> Services Management Console and first stopped the OracleDBConsole, CPU was still 100% busy. Then I stopped the OracleINFRAControl and the CPU went to 0%. Then I restarted the OracleINFRAControl and then OracleDBConsole and now the CPU is hovering around 2%.
I ran some tests from another machine and everything seems fine.

System Slow/Freezes on startup - svchost.exe uses 8GB+ RAM

Hi,
At each boot, my computer is low. In task manager i see
svchost.exe -k LocalService will max out around at around 8GB of 16Gb RAM and the process disappear after 4 and 5 minutes and my computer works normally after that.
I have no idea what is going on but I suspect 4 files of 2 Go in C:\Windows\System32\NetworkList\Icons

Hi,
For this problem, in my opinion, it would be better to make troubleshooting with Windows startup diagnosis tool, you can refer to the contents of the link below for more details:
http://social.technet.microsoft.com/wiki/contents/articles/10128.tools-for-troubleshooting-slow-boots-and-slow-logons-sbsl.aspx
Since you said it work fine in Safe Mode, you can also check is there any program start up with system, then try to disable them for test if Windows works fine.

EP 6 SR1 - jlaunch.exe using 25% cpu under no load

Hi,
We installed EP SR1 (patches SP9) on virtual machine on MS Virtual Server 2005.
J2EE server (jlaunch.exe process) is using 25% cpu on average without any load (no user interaction).
Response is slow when accessing the portal.
I assume this is not a normal behavior of J2EE engine.
Has anyone else experienced this problem, suggestions on how to resolve it will be appreciated.
Thanks!
Rob

Hello,
I have exactly the same problem with EP 7.0 on NW2004s under Windows 2003 x64.
Does anybody know how I can solve this problem ?
Thanks,

Webcached.exe uses all CPU on IAS server

Hi, I'm having trouble with a process called webcached.exe according to Windows task manager, this process takes all available CPU resources, so our IAS server hangs. Anyone why this is? Any help highly appriciated! I'm pretty new to Oracle Application server, and have not experienced this before...
Is there a way to "go around" web cache until this issue is resolved, i.e. not use cache for a while perhaps? Longer responses are better than complete hangups....
I've tried to just stop the webcache process, but this apparently is not the way to go...
Windows server 2003 + IAS 10g (9.0.4.1.1)

Your post is a while ago... but you should upgrade Web Cache to 10.1.2.3, or install it in a separate location and configure it against your backend application. This is supported.
Webcache 9.0.4 is known to have some performance issues :)

Ituneshelper.exe uses 50% cpu

I walk into the room and my wife is playing her games on Pogo. I hear the dell fan running like mad and ask her how long it has been running so loudly. She says for over an hour and it won't stop. I look at task manager and see ituneshelper.exe is using 50% of the cpu.
Any ideas on how to fix this?

Ok, stopped iTunesHelper and then ran iTunes and quit iTunes: everything is now behaving. (I'm not even seeing iTunesHelper in the Processes tab when I open iTunes now.) Odd? I've also just restarted and run iTunes without any any spike in CPUs by iTunesHelper as well. ??? (Tentative cheers!)
When I first upgraded to 7.5, iTunesHelper was immediately using major CPUs, even after I closed iTunes (but not of course after ending the process). I restarted the computer and opened iTunes (and had to reinstall missing files) and ran into the same CPU situation, which seemed to be upon opening the program if I recollect.
I'll post again if this issue has not resolved (as it currently seems to be). Thank you, thank you!!

Apple mobile device exe used excessive CPU

I am running iTunes on Windows 7 32 bits and as sson as I open Itunes, Apple Mobile Device exe. will start to use up to 50% of my CPU. Even when I have closed iTunes this contnues. Is there a fif for this since it will of course mean that all other processes will be slowed down and that the heat from the CPU finally will lower the life of my lap op.

Major issues with plugincontainer.exe using high cpu freezing firefox 34

Plugincontainer.exe is ruining my experience with firefox by constantly causing it to freeze due to high cpu use. Please advise of a work around or other solution. Thank you.

The only solution I have found was to downgrade to Firefox version 30.
The odd thing is that the high cpu does not happen on all web sites. wsj.com (Wall Street Journal) is fine, but cspan.org is not.
My PC does not freeze up, but it has a sustained CPU usage of 70 to 80 percent. I am running an Intel Dual Core on Windows XP.
Is this the case that my CPU is just to slow? This should no be the case since version 30 runs at the regular 15 to 30% usage.
Forgot to mention that this is the Adobe Flash player that is causing the high CPU readings.
Thx

ITunes v7.7.0.43 syncclient. exe using excessive cpu

I recently updated iTunes to v7.7.0.73 and my orginal iPhone to v2 and the syncclient.exe process is going nuts! As soon as iTunes is started, this process consumes almost all available cpu and creates constant disk reads (VERY BUSY) until I kill it.
I found similar posts on the iTouch Discussion so this is clearly a iTunes problem. Disabling Sync in iTunes will prevent the process from starting but...
FIX IT APPLE!!!

Qttask.exe using 95%+ CPU

I've installed iTunes on my PC and it's now virtually come to a halt.
The culprit appears to be something called qttask.exe which is taking 95-99% of my CPU power.
I understand this is something to do with updates for Quicktime.
I've uninstalled once and re-installed again, but still the same result.
Any clues on what's wrong and how to solve this?

In QT settings uncheck system tray icon. Then go to Start>Run and type in msconfig and click OK then click on the Startup tab and uncheck qttask.exe. This will stop it from loading on startup and let you know if QT is the culprit, which unlikely it is

Colsvrcore.exe using 100% cpu load - how to debug ?

I'm new to Zenworks and facing a high load issue on one of my Collection Servers.
Colsvrcore.exe goes 100% load after 30 sec and stays there.
My question is: How can i debug on this issue ?. I was thinking bad data or something could lead to this high load.
