Does svchost.exe ever hog all your CPU resources?

-- Yes (When does this occur? How frequent?)
-- No (Lucky you!)
-- Sometimes (When does this occur?)
-- I have no idea what you are talking about. (Then I guess it's not an issue for you.)
-- I don't use Windows.

I had the problem for awhile although I voted no. I got rid of it by turning off email scanning in Norton Systemworks. Haven't had a problem since. My view: let the antivirus software from my ISP and on my computer protect me from incoming email. Outgoing email, people I send email to should know better than to open email from me. Happy

Yes, svchost.exe also hogged my CPU resources (98%)
by mustang_r / April 24, 2009 12:55 PM PDT

This used to happen, about 18 months ago, when I was using an early version of WindowsXP. I would simply use the "stop process" option in the Task Manager to stop or overcome it. At some point thereafter, it just stop doing it, and because I didn't notice exactly when it stopped, I don't know what additions or updates might have corrected the issue. I do remember that the problem usually presented when I had 3 or more 'online' windows open, and was visiting multiple sites - I think I also had a photo-editing s/w program open at the time. I have noticed multiple 'svchost.ex' processes listed in the Task Manager now and wonder if maybe having more might have resolved the issue? I don't know.

On occasion it did, until...
by Paul C / April 24, 2009 7:23 PM PDT

...I learned a few tricks.

1. Do you really need Windows' Indexing your drives for supposedly faster searching? No. Right-click the drives in Computer (Vista) or My Computer (XP and earlier) and clear the check box for indexing. Click Apply, then follow the prompts to apply to all folders, subfolders and files. If Windows says if can't apply this to a folder, click "Ignore." Repeat for all drives/partitions. I personally don't use Windows' hopeless search function; instead, I use the freeware Locate32, available at It's blazingly fast, accurate, and only updates its file index upon your request through its Updtdb32 applet.

2. In the same popup window, clear the check box for file compression. In this day of 1 Tb hard drives, do we really need to compress an entire drive/partition?

3. Any version of Windows from Windows 2000 onward starts any number of services, all of which consume both RAM and CPU resources. Many of them are totally unnecessary and only gobble up system resources. Go to and select the guide pertaining to your operating system (Windows 2000 Service Pack 4, XP 32-bit Service Pack 3, XP 64-bit Service Pack 2, Vista Service Pack 1 or Windows 7 Beta). The "Safe" configuration works fo almost all of us; if you have a different configuration, then leave that service available. Oh, and did I mention that you should have your PC updated to the latest service pack available for your OS? You should. Doing this WILL result in a lower drain on system resources and improved boot/shutdown times. However, results may vary, your mileage may vary, past performance is not a predictor of future results, and all those other disclaimers. Wink

4. Malware is a frequent cause of such problems. If svchost.exe suddenly starts gobbling up resources, I'd pay attention to any software I'd installed immediately prior to the problem starting. If I hadn't installed any software, or if I determined that the newly installed software wasn't causing the problem, then I'd scan my PC for malware with a number of tools, both offline and online; a practice you should be doing.

Hope this helps,

It did happened to me a couple of time. After doing some research in google, I found that it was caused by a virus which resides in the memory when you start the machine running my xp.

I had this problem several months back also. Extremely frustating!!! Tried everything, google, process monitor, process explorer, etc.
Turned out it was my Nvidia nView Desktop Manager. Once I turned it off everything was good.

100% CPU usage no longer a problem
by theccur / April 25, 2009 12:05 AM PDT

Using XP on a single processor system, this issue was a frequent, trying and insoluble problem. Different programs would run at 100% at different times and under different conditions. I learned to endure it. I now use Vista on a 4 processors system and have never had it recur.

svchost.exe hogging resources

A rogue spyware program kept reloading asking for updates to be installed. My tech was finally able to locate and eliminate this program. It was buried pretty deep, so it tokk several tries to eliminate this nuisance .

svchost cpu usage
by sistersilver / April 25, 2009 12:24 AM PDT

no problems so far. I just got a new computer-Vista-with a 64 bit system. Still, I will check out the software you suggest. I also have a triple processor because when I first got Vista nothing worked...also...4 gig hard drive instead of 2 or 3 plus 2 gigs of memory made it possible to work with the computer and stay up to speed with no problems. Vista is definitely not for small computers.

svchost CPU problem solved
by voyagerxv / April 25, 2009 3:02 AM PDT
In reply to: svchost cpu usage

I recently had the svchost problem with my PC. I was eventually able to narrow it down to the new version of AVG (8.5.287). I used Autorun to help find the problem. AVG recently added a component (Resident Shield) to block malware and I found it was running a quite a few svchost processes and using a lot of CPU and disk read/writes. It made videos hard to watch. I took a glance at my network antenna light and it was flickering on and off like crazy. I turned off the "Resident Shield" component and all seems well now.

Varying results in different machines and OSs.
by brianlevyesq / April 25, 2009 9:21 AM PDT

I have 3 computers, 1 runs Vista and have had no problems, my desktop with XP SP 2 (it freezes when I tried to upgrade to SP3) had the problem until I went in and disabled everything but the most basic needs and now it seems better but still has fits but I know it is my tax applications and nothing I do with them seems to help. My 3rd runs XP SP3 and with the same tax apps seems to do better. The laptop and desktop are running 2 gigs so not an issue of dispaate ram in them.

I also have a laptop and a desktop running 2000 Pro and neither seem to have any issues. Both use 1 gig or ram. These are lightly used so may not be as much an issue based on apps. I have noticed that there are fewer resources needed to run Wordperfect 11 and MS Office 97 with all the updats as to viewer to allow opening and saving to the Office 2007 formats and ODF compared to Office 2003 that seems to be a hog. I may dismount 2003 from my XP machines and mount 97 with the same upgrades to keep is lean and mean.

100% CPU usage, slow system (FIX)
by Erick Erickson / April 25, 2009 3:05 PM PDT

First end the task by going to task manager highlighting the program cisvc.exe and click end process. Your cpu usage should go way down to say 3-10% approxamately. This is an index service file activated by cidaemon. Neither of this can be deleted- its part of windows but it can be shut off.

Next go to your control panel and start "Add or Remove Programs" . After its up go to" Add/Remove Windows components" this will start up the windows components wizard. Uncheck the indexing service click on "next", it will remove this component, then restart your computer and it will not load up so cpu usage should be normal.... eeerickson

Does svchost.exe ever hog all your CPU resources?

Yes, i felt several times. Actually as i connect to Broad Band, the entire system get halted for at least 5-6 minutes. Even task manager-window could not open. After 5-6 minutes, when it open we could find number of svchost.exe window are running simultaneously. i felt that number of svchost.exe applications are increasing with time. Whether it is due to update is some softaware life ADobe, Firefox, Avast AVS xtra. Please anyone guide me to outcome from this.problem.

This discussion was enlightening
by JoMilton / April 25, 2009 6:23 PM PDT

I don't have this issue very often - that I know of - but I was frustrated up to now, not understanding what svchost was. My old XP notebook frequently choked due to low RAM and a slow dialup connection,which meant all automatic update functions hit the net at once and jammed the machine up, and I turned off auto updates and kept taskmanager open all the time to deal with it. My new Vista notebook has broadband and resources in plenty for my use, BUT it suffers from regular mysterious freezes, when it suddenly goes "silent", everything stops, it refuses to respond to commands, and I have to wait patiently for a minute or two. I shall look harder at svchost when this happens in future.
