Svchost.exe Process Causing High CPU Usage. How To Fix It?

I searched the web for answers and found that someone else had the exact same problem and used a combination of Rkill and TDSKill executable programs to stop malware processes and remove rootkits. I never thought of this before because i had no idea what a rootkit was. After rebooting google worked fine and i found that the particular service host. Could we have that in english please? Some time ago, Microsoft started moving all of the functionality from internal Windows services into.

If every single service ran under a single svchost. Those services are organized into logical groups, and then a single svchost. For instance, one svchost.

Additionally, if you are noticing very heavy CPU usage on a single svchost. The biggest problem is identifying what services are being run on a particular svchost.

If you want to see what services are being hosted by a particular svchost. You can right-click on a particular svchost. This will flip over to the Services tab, where the services running under that svchost. Or you can double-click on a svchost. Open up Services from the administrative tools section of Control Panel, or type services.

You could also use the command prompt to disable the service if you choose. Did this solve your problem? Sorry this didn't help. Tell us about your experience with our site.

I turned off the automatic updates and rebooted, but it has not helped. Does anyone have any faith in the various fix programs that are advertised? Also, the updates my computer was trying to install was for Microsoft Office , which I only have a trial version of. I also tried doing a system restore without success.

Seems to be my problem too. Seemed to come about when downloading the Office updates. I even talked to the fine folks at Microsoft, but they were not any help at the top of the year. They said it was virus-like behavior and they could have a tech scan my computer. I opted out of that one though. I then found this web-site ran the reinstall. Microsoft ought to do something about it. Now, the only problem is when I install updates again, cause I go back to the problem. Please, keep uploading this topic if new solutions are found.

If you have this combination, everytime Windows checks for Microsoft updates not the Windows updates , it will cause to svchost. If you wait long enough, the system will run normally eventually, after he has checked for updates. You can disable automatic updates temporarely to have a working computer again. Maybe you have to reboot. You can kill the task svchost. Following the patching instructions included with this patch resolved my problems entirely.

Then, you may receive an error message in the svchost. Thanks Leo This one has been driving me crazy. Ir also accounts for the sudden loss of sound on the machine! I had this problem. I tried lots of things including patch KB I had to back this out because it made it worse. The computer is running fine now.

What did I do?? This might not make any sense but the only changes I did was to shut Mcafee down for a day and I changed the time of when the Windows automatic update would run. A strange fix for a strange problem. For the overheating, I also took my computer outside, opened it up and blew the dust out of the insides. I had this problem and I was about to completely re-install my PC after scanning the system with many different spyware and virus scanners for weeks.

I was following the same procedure as Organicman writes earlier: The reset script for windows update service did the trick. Many thanks Leo for this golden tip! Add me to the list of frustrated and disillusioned Windows users. Things got even more puzzling when a third computer started having the same problems. Truly, our computers were becoming next to useless, and chalking everything up to coincidence was becoming a stretch. I tried everything I could think of to fix things without success and was about to reformat.

In case you are not aware, good old MS have finally issued a fix. I contacted microsoft support the fix the sent me seems to have taken care of the problem and I am able to use automatic update with no problems. Thank you for contacting Microsoft Windows Update Support.

My name is Kino and I am glad to work with you. To contact me, you can send emails directly to my account: From your description, I understand that the Svchost. If I have misunderstood your concern, please feel free to let me know. I understand the inconvenience you have experienced. Please be assured that I will do my best to help you resolve the issue as quickly as possible. Recently, we released a hot fix, which addresses this issue. Based on the current status, I suggest we try the following steps to troubleshoot the issue.

For more information related to this issue, please refer to the following Microsoft Knowledge Base articles:. When you run Windows Update to scan for updates that use Windows Installer, including Office updates, CPU utilization may reach percent for prolonged periods. You receive an access violation when you try to install an update from Windows Update after you apply hotfix package This problem sucked several worthless hours out of my life just last night, hopefully tonight it ends.

If WMI uses svchost, this may be the missing link: It then restarts the Automatic Update service again before forcing an update cycle to start. It appears that Microsoft has pushed the fix for this out tough ironically automatic updates. Even if you visit the Windows Update website and manually try to get patches, it will fail until the service is enabled.

In fact, just starting the service is not sufficient, it must be set to an Automatic startup. If you are suffering from this problem, you can download Process Explorer on another computer and run it on the problematic machine without installing it. Right click on the offending instance of svchost and lower its priority.

It may still burn all the cpu, but when you use the system, you should have a higher priority so the system should run at a reasonable speed. I think it is because as mentioned in previous comments auto updates is scanning the logging info for its internal use and takes a lot of time especially when the log is big due to a lot of pervious auto updates and also the scanning algorithm might have just been changed after recent update ignorant to this fact.

Remove and reinstall clears the long log so it becomes faster. I just wonder it might come back after many new updates. Thanks for the posts here. Doing a whois, this does not appear to be a microsoft server. I am not able to recieve any windows updates via automatic or windows update site.

When I try to update the svchost connects to footprint and eats my CPU. Could this be an svchost virus? Maybe svchost has been modified so that it loads an infected dll or something. Process explorer is great. I quickly confirmed that it was windows update eating eating my CPU. On my computer the svchost problem was related to the DNS Client service. Each time I tried to access the internet the svchost. The following svchost process was causing the problem. They may have to pay for divorce proceedings.

Anyway I think this CPU usage is still high for and after shutting down quite a few services that i read carefully about doing firstbefore shutting them offin msconfig. Mine is lower but wonder what decrease in CPU usage others are getting after the update.

Thnx appreciate any input…….. In light of information from this article I found that part of the problem can be associated to regsvr I recently tracked the issue back to a non-Microsoft software deployment we had previously ago that would replace C: The deployment team said this would not be an issue to accept these files as all attempts to use a CD and restore the files would fail.

The first problem caused by the incorrect version of regsvr I used RegCure and it appears to have fixed the problem. I tried to fix a PC that actually froze immediately after booting into windows XP.

Virus and spyware checkers did not identify any problems. Turning off the service resulted in a normal boot and a working operating windows system. This post is being writen on the problem PC. Virus or otherwise infected file? Who knows, its worth a play — it worked for this PC. I just had this problem on a Dell Optiplex SX and had scheduled a motherboard replacement on it before I read your article and followed you advice.

After disabling the service the computer bacame stable and responsive. What was interesting was that the Dell guy showed up and did the motherboard replacement. I told him what I had done to alleviate the problem, but he wanted to do the replacement anyway. Amazingly, that actually fixed the problem! Windows automatic updater could be turned back on and the computer was fine. In other words, it was actually a hardware problem that I had circumvented by turning off that automatic uptates service.

Hi I have a worm insvchost. I used nod32 but also the same problem. I have no way but re-installing windows because the system is so sluggish. I think there is some problems with ICAgent I have no automatic update in computer management section!!! This is a persistant issue. I have done all that was suggested but still have an issue. I disabled the Auto Update service as described and all was well. However, on next boot I had the problem again.

With a little investigation I have discovered its related to the Firewall settings. If I switch off the firewall, the problem disappears. I do not want to leave the firewall off so I have put the priority for this instance down to the lowest value and am suffering it.

Tried everything I knew to do. Have no idea if it hung up or what. I run the same Spyware on my PC and have never had a problem. I found another solution for you. DLL that was the problem.

From there changing it to the local admin or domain admin accounts works fine. Please, help me ; I cant stop these processes. I must restart OS always when this window is revealing. I have found my own solution to this problem. I use one of 2 programs that keeps a watch on processes that use a lot of CPU time and lower the priority for these processes.

One of them is Process Tamer http: I always hated how I would go to a machine and whether it was automatic updates or manually updating the machine would freeze while looking for updates. Well using these programs will keep you computer usable while doing updates. The main machines I have noticed the problem on all have Celeron P4 processors. I hope these programs will be of use. Thanks for the interesting article. Hey, just thought i would add this. My service host was hogging all the memory it could because of my stupid HP printer network… I killed it and everything went back to normal.

I had the same svchost issue on two computers and tried everything above with no good result. It can be temperarily disabled by right clicking on it in the lower right corner of your display and selecting exit.

It can be removed from the Startup folder to permanently render it harmless. Curious, not sure whatelse could have ocurred?

I had this same problem, and followed your advice. Once I downloaded Process Explorer, I was able to see all the processes tied to the svchost. I went into Computer Management as recommended and disabled Auto Updates.

I then started to disable other services until the problem did go away. Thanks for the help! Hopefully this will help others with the same problem. And hopefully Microsoft will provide a fix. Had same problem with HP printer software. Even with digital imaging monitor tuned off, still occurred. Uninstall HP software, back to normal. Found a fix on internet. Thanks this has helped alot. I had the svchost cpu problem and tried diableing updater but still occured.

So I went through one at time and stopped RIP Listener which is a servce that listens for information from a router and that stopped the cpu usage problem, but while this has been happening I have had no conectivity can not ger IP address from network.

There was also an unauthorized user account under RIP Listener. Another vote for the bloody HP service. The Process explorer that was mentioned in this article is truly a wonderful piece of software — it showed me immediately that the culprit was the HP Network Devices Support service.

It appears there are a number of resolutions to the svchost high usage issue. I replaced the host file with the original which is 1K and the problem is gone. I tried every solution given in this site. I too had a problem concerning with svchost virus, I too worked a lot on that, and got a solution, for the help of users, I am providing the link to my article Getting rid of svchost virus. This article is recommended for those who have problem concerning with virus called svchost, and not with those related with printer, or other things.

Those viruses cannot be detected using antivirus softwares, they are called as rootkits. Just read my article if you want to fix the virus which I have explained. Has anyone had this problem AND had explorer hijacked? Using task manager I too changed the HP settings to manual and found another problem: I had a user experiencing long periods hours of high CPU utilization from svchost.

I was immediately able to determine the cause of the problem. It was an HP who else printer discovery service that was installed during a recent all-in-one printer connection. Now I can confidently address my problem with the offender!

Thanks to Ask Leo! I can kill the process, but that is temporary. Is there a permanent fix? Has anyone contacted HP about this? I think I found a fix for my problem, or at least a workaround. I have had this svchost cpu-hogging problem since installing an HP wireless printer. Leo, thank you very much for your help on this problem. Coincidently, however I had installed a new HP Wireless D printer, and after reading the comments after the article I thought that would fix the problem.

After installing that and rebooting by computer, I was happy to see my CPU usage to drop to normal levels! After installing Norton , my problem still existed. Actually I have been contacted on occasion by various folks in tech support roles for major companies. And I also have a fairly significant readership in India.

I got the following suggestion:. It could be a problem for folks not already behind a firewall. I am tired of all of these problems with svchost. I have decided to get a MAC. Life will be much easier. My computer is extremely slow as of late and when I open up task manager there are several iexplorer. The two processes now take it in turns to torment me by slowing my computer to an unbarable speed.

Please could you give me some advice? I had AutoUpdate turned on to download but let me manually install but turned it off completely and svchost. I had to call microsoft support. They ran tool to re-register all the DLLs using regserv.

This solved the problem. I installed it and it works! I used their tool vs. I put Help Service and Windows Update service in their own svchost and this fixed things. Hi, Since yesterday my laptop is getting slow because of windows updates. I set a recovery point every time I made a change to my system and was able to pinpoint where things went south with Svchost. Problem solved for me. I guess that SP3 is not watertight for all different devices esp when these are relatively new. I tried all the suggested fixes I could find, even did a reinstall in place — all to no avail.

BTW, this is repeatable: My system has had the same problem from time to time. By the way Leo, I truly truly miss the North West!! Hello about this issue regarding high cpu usage from svchost. You can turn off Microsoft Update at the update site that Microsoft Update takes you to. Dont know if that helps in your case i corrected many windows installations in this way give it a try if you allready depleted other solutions.

I could not perform a Windows update even with going to the Microsoft Update site with Internet Explorer. I was unable to start the automatic update services in services. It can be downloaded here: I have been plagued with this issue at home and at work. My IT department gave up on my computer. HP put in a new mother board. I corrected both from this information below. I luckily found your web site regarding this issue when I did a google search for svchost.

I thought it was my internet provider…a virus…my computer…etc. One tech called me back at 3 am this morning after doing many scans to find the problem, only to tell me he could not fix it. He recommended I reformat my computer. I started to google svc this morning and came accross your site. I followed your instuctions to download the Process Explorer and to run it to find out what the problem was.

It showed me only 1. They seem to be related to my network — when I disable the network, the spikes stop. My network has 2 computers, one connected wirelessly and one connected by cable.

Task manager showes that the network itself is not using a lot of CPU. Problem is now gone, and internet access is fully functional. Hope this is of some help to others with similar problem. The key for me was to use Process Explorer.

Many thanks to Leo! But then another app would, after a few minutes, move in and take the place of those two. Netstat shows that there are connections to the machine listening if I remove my network cable on ports , etc. Ending those services stopped the usage. With Process Explorer you can. Reading previous comments, however, the problem seems to be with the svchost process itself, cos everyone has different process to unleash processor utilization! Otherwise, they should find one asap. I used process explorer, downloaded from Microsoft web site, to identify the problem svchost.

Clicked on properties and then services. Found that it was a recently re-installed HP printer file that was monitoring my network.

I stopped it and no more CPU problem. After 8 months of having this problem, the ProcessExplorer program helped me find the culprit my HP Digital Image program. I downloaded the Process Explorer and I think I found the culprit on my computer. I recently installed a new 4-in1 HP unit and it has an image monitor that must run constantly. As soon as i disabled it, my computer sped up to normal.

I am so glad that I found your site!! My issues is my svchost is 5. Did not start up again when I opened Internet Explorer 7. I tested printing after rebooting. When I disable automatic updates from Services, reboot, and view Processes, there is another high CPU usage on regsvr The issue was the HP printer for me as well…this defintely seems to be the fix!

I simply used the steps above and stopped the HP imaging monitor and then disabled it. Printer still works as well! Thanks for the help everyone! I was told it was my processor, that I had a trojan, that I needed a new bow….. I had the same expierience, and the problem was not a virus, but it was because the PC with the svchost. Now on PC B the network was not running, and all I need to do was start the network, and voila!

Hope this will help anyone expieriencing this kind of problem. I have been having this problem on three of the 24 computers I maintain.
