Svchost.exe & Wuauclt.exe Cannibalizing My CPU Usage on Internet ???
Ive been pretty happy with WinXP for the most part until recently.
When I get on the internet the CPU usage goes to 100% Usage and does
not stop until I de-activate the Windows Update Client using the NET
STOP WUAUSERV system command.
When I use Sysinternals Process Explorer I notice the following;
SVCHOST.exe is the process using the most CPU cycles. There are 2
wuauclt.exe processes that are running as a children under SVCHOST.exe.
The first wuauclt.exe is present after I bootup. The second wuauclt.exe
process appears when I get on the Internet.
To temporarily resolve the problem I do a ...
c:>net stop wuauserv
.... after serveral minutes wuauclt.exe disappears
.... and then wmiprvse.exe disappears.
It takes several minutes for this to occur which I find unusual.
Then my CPU Usage returns to Normal.
My Windows Update System is setup on a NOTIFY ME BUT DO NOT DOWNLOAD
setting.
Im not sure whats going on. Any help is appreciated.
If you have any ideas plz let me know.
Ive provided additional information below.
Thanks

Re: Svchost.exe & Wuauclt.exe Cannibalizing My CPU Usage on Internet???
Disable Automatic Update completely. Every second Tuesday of the month
MS puts new updates on the Windows Update site. Go there for your updates.
Re: Svchost.exe & Wuauclt.exe Cannibalizing My CPU Usage on Internet ???
Check your windowsupdate.log
<title>KB902093 - How to read the Windowsupdate.log file</title>
BTW pstat might capture your current execution better than tasklist.
In any case tasklist /v would at least show the CPU time per process.
Re: Svchost.exe & Wuauclt.exe Cannibalizing My CPU Usage on Internet ???
Thanks for the Feedback.
I think I had Windows Updates turned off a while back. Probably why I
didnt have any problems for the longest time.
Ive looked at my Windows Update Log, but I dont know intimately what
its telling me, other than it updated this particualar thing at this
time. I will check out the MS knowledge base about how to read Windows
Update Logs. Thanks.
ONE THING I forgot about is ...
Ive gone to the Microsoft Windows Update Page. When I try to update,
the process bar just goes round and round and never does anything. Im
not sure if the server is busy or its something else.
Of course Im on a 28.8 modem so thats probably not helping matters. Ive
also wondered if the Automatic Update Client (Wuauclt.exe) process is
interfering. Maybe you CANT DO a manual update and have automatic
update going at the same time.
The joy of Windows!

Re: Svchost.exe & Wuauclt.exe Cannibalizing My CPU Usage on Internet?
When you use Automatic Updates to scan for updates or to apply updates
to applications that use Windows Installer, you experience issues that
involve the Svchost.exe process

Re: Svchost.exe & Wuauclt.exe Cannibalizing My CPU Usage on Internet ???
I had a few issues with svchost, specifically c:\windows\system32\lhmsvc.dll running via svchost.exe -k LocalService.
Basically, my issue seemed to be with Windows Update
There are a number of svchost related issues resolved in XP service pack 3, so I would first try applying or reapplying SP3.
If that doesn't work, try updating the WindowsUpdateAgent as per http://support.microsoft.com/kb/932494/en-us and http://support.microsoft.com/kb/927891/
You could also try these steps: http://support.microsoft.com/kb/927385/en-us
I have had luck with these steps, which made a sluggish PC seem fresh again, but it depends on what service within svchost is causing the issue.
To help determine what is causing the problem use process explorer to try and find some more detail of exactly what process is causing the issue, slowly stopping each service until the CPU stops running at 100%.
