Windows update 100% cpu at every boot killing me

Every reboot, windows update runs 100% cpu for 5 7 minutes.
if I turn off automatic updates it doesnt happen.
(but then...no updates. so not a solution).

its xp pro.

I renamed windowsupdate.log (old) because I thought 1500k was
pretty big, might have been slowing it down. this had no effect.

windows update from IE6 and IE7 works fine.

I dont understand the log and I dont know why it ramps the cpu
every time I reboot this machine. this has been going on for
about 3 months and I am tired of that.

how do I reinstall windows update totally
or reslove this problem?

thanks
James

Jim,

Here's a temporary workaround. Go to Start > Run > type in

net stop wuauserv
Click OK or press Enter

Show hidden files, folders, and system files
http://www.bleepingcomputer.com/tuto...l62.html#winxp

Navigate to WINDOWS\SoftwareDistribution\DataStore
Delete the *contents* of the Logs folder and delete DataStore.edb
NOTE: Deleting the above will mean that the update history shown at
Windows|Microsoft Update will be cleared. Until updates are once again
done from either site, nothing will be listed.

Open the WINDOWS\SoftwareDistribution\Download folder and delete *all*
contents.
Close the window

Empty the Recyle Bin
Go back to Start > Run > type in

net start wuauserv
Click OK or press Enter

Download the hotfix would be my recommendation. KB927891

It works sometimes, sometimes not, from the reports I've been reading.

I made a batch file with your instructions. You can copy the below, paste it
in notepad (Start -> Run -> notepad.exe) and save it as anything.BAT (Save as
Type - all files). The only thing I've noticed from this fix is that if
you've setup your computer to do the Microsoft Updates (which includes
Office), it will reset back to Windows Updates. Not sure yet if the original
problem returns.

===copy below===
@echo off
net stop wuauserv
cd\
cd windows
cd softwaredistribution
cd datastore
del * /q
cd logs
del * /q
cd..
cd..
cd download
del * /q
net start wuauserv

You may wanna shorten that to a
cd /d %windir%\Softwaredistribution\datastore
just in case.

Bye,
Freudi

This problem has affected various systems (not all) at 2 sites I maintain
since the February updates were released.

I created this batch file (which also re-registers the Windows update
components), and it has been successful on some systems and not on others.

I've also installed KB927891 - which I thought was working, but appears to
not be the solution. Strangely, I recently downloaded/installed KB929338 on
a system and noted svchost.exe appeared to max out at only 50%, so the system
was otherwise useable.

I really hope Microsoft resolves this one soon...

Hi! I;ve tried the hotfix no. kb927891 & 916089 perviously. The problem is
still not solved.

I work in a large network environment and am having the same problems
with the ntdll.dll in svchost taking up 100% cpu. The strange thing is
it seems to be only happening on laptops, whether they are connected
to the network or not. We use WSUS from a central server to maintan
windows updates. Would the work around mentioned above still work in
the WSUS environment.

I tried the hotfix from Microsoft. That doesn't solve the problem at all. For
my case, this issue only happens on old machine(eg. P3 with 256MB RAM and
only during first 10mins after startup), the newer machine has no problem
with that.

You might want to tried the outfix, i think it did solve the problem on case
by case basis. I read through some newsgroups previously, it does work for
some other people.
