svchost. exe high cpu usage problem

hi!

I'm having problem with svchost.exe that take up more than 80% of my CPU
Usage. From the Process Explorer, i noticed that this svchost.exe is actually
use by Automatic Update Services. It will drop to below 10% when i cancel
this service. When svchost.exe is running at abouve 80%, my pc becomes
extremely slow. I've tried the hotfixes from Microsoft KB_916089 & KB_927891,
but it didn't help.

I'm getting the windows Update from our WSUS server. I've tried to update
using Microsoft website and WSUS, it doesn't make any different. I've did an
fresh installation and scanned the system using Norton Corporate Edition. All
these don't seem to make any different.

Here's the spec of the PC.
P3 500, 384MB, 8GB HD. Installed with WinXP SP2, Office2003 SP2, Visio &
Project 2003 SP2, Media Player 11.

Any idea what can i do from here? Pls advise. Thanks.

Temporary workaround:
Open the command prompt (Start -> Run -> cmd) and enter the following
lines and hit [Enter] after each of them:

net stop wuauserv
cd %windir%\SoftwareDistribution\Datastore
esentutl /p datastore.edb (Confirm the warning message with OK)
esentutl /d datastore.edb
net start wuauserv

Check, whether that helps. In case it doesn't, back to the command
prompt and:
net stop wuauserv
del %windir%\SoftwareDistribution\Datastore\datastore. edb
net start wuauserv

Deleting the datastore.edb will leed to a loss of the Update History
displayed on the Windows/Microsoft/WSUS Update site.

Bye,

I got this from another newsgroup but it worked for me:

I've been stuggling with this problem myself. After days of looking
online, installing patches, and people telling me I had a
virus.....sort of hard to do since it was a FRESH install.
None-the-less, I'm glad someone has a solution that works.
