Recently, a svchost.exe in the task manager has been running at 50% CPU. This has been happening occasionally. When i use process explorer it has multiple programs running under it including sound, automatic updates and others. Is there a way for me to stop the extreme CPU use of this svchost?

Hi, I have the same problem, I can see about a dozen svchost.exe on my task manager and many ccSvcHst.exe also. Memory usage goes up to 900mb and cpu usage very erratic and many times to max cap and my system slows bad.
I'm going to stay close to your thread to see if some good soul comes up with some help.
Pietro

start\run\msconfig -startup tab

disable as many unneeded startup items as you can. (make sure you know what you are disabling though, because a few in there might be needed)

Then go to start\run\services.msc

Turn off unneeded windows services. There are quite a few, and you need to know which ones to turn off. Do a quick google search on "disabling XP services" and you should find several good walk-throughs on what to turn off, and how to do it. Be careful here too because if you disable the wrong one you won't have internet, or worse.

Just a hunch but I bet it's ipv6, which is entirely unnecessary and very easy to uninstall

Hello odin3500 and Pietro Felicce

You need to use Process Explorer to identify which svchost.exe is using all the CPU.


ccSvcHst.exe is a Norton process and I am not surprised to see you are having a problem with Norton
Can you reinstall Norton and see if that helps?

Another option is to ditch Norton and get yourself a free antivirus etc. such as Microsoft Security Essentials
Your whole system will run better without it

Hi, thank you for your help. I turn on WinTaskMgr and reads only memory usage, how do I turn on Process Explorer to read CPU usage?

odin3500

As suggested by Suftop disable everything not needed to run at startup
Start/Run and type in
msconfig
OK

Startup Tab
Keep the page open then go to the link below. It will tell you what all the entries are and whether you can disable them or not. It will also identify any malware. Disable everything which is not needed to run at start up

http://www.sysinfo.org/startuplist.php

Read the Key at top of page. Use the Search box to check all your entries

When you reboot you will get a message saying you have started in "Selective Startup" Click "Don`t show this message again" then OK

Also try turning off Automatic Updates

Pietro Felicce

Maybe this will help you with Process Explorer
