Cpu Usage rising to 100% after opening automatic updates

Hi,
I'm a IT Developer, and around February I found that the CPU fan is
always on after system startup. After a month, I found that process
SVCHOST.EXE is using 100% CPU. I tried a few times to terminate the process
and found a lot of system services terminated, and the system forced a
shutdown after 1 hour or 2.
On May 4th, I used Rising Firewall's process monitor to check the
process. The commandline starting the process was " -k netsvcs". I didn't
solve the problem until last week, I tried to stop automatic updates and the
problem disappeared. Then I found a better way ------ Stop using Microsoft
Updates, and switch back to Windows Update. The try was successful, so I
believe the problem was cause by Microsoft Updates.
According to the Rising(China) IT
News(http://it.rising.com.cn/Channels/Inf...64d42128.shtml),
the problem was caused by a (or a series of) updates, and there was a
conflict with Microsoft Office Outlook 2003 (which happened to be installed
on my computer), and will result in the condition I described in the
previous part.
I hope Microsoft's IT Professionals can solve the conflict caused by a
security update, and hope you can contact me via email if you have already
solved or is planning to solve the problem.


MZhao,
IT Developer,
China

For a fix to this problem, please do BOTH of the following:

1. (not for Vista) Download and install update KB927891 version 3:
<http://support.microsoft.com/kb/927891>
and then restart Windows.

2. For 32-bit systems, download and save to hard disk, and then install:
<http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/WindowsUpdateAgent30-x86.exe>

If this produces an error message about "Update agent already
installed", then execute the installer again manually, with parameter
/wuforce as in (at a comand prompt window):

WindowsUpdateAgent30-x86.exe /wuforce

Then visit Microsoft Update again, and report back whether your problem is
fixed.

2 problems:
1. The CPU Usage is still going to rise to NEARLY 100% when checking updates
from Microsoft Update Website
2. The whole update checking process took nearly 6 minutes, which is not
acceptable (if it happens every time)

Now I stopped Microsoft Update again, and I hope you can give me some
suggestions.

This no longer matters, as the CPU consumption is in a background process
with lower priority than before, so the update checking process will no
longer disrupt your foreground activity.

As this is in the background, it does not really matter how long it takes:
it is not interfering with your usage of the PC.

The length of the checking process seems to be associated primarily with the
presence of Office 2003. Make sure your Office installation (particularly
MSO.DLL) is totally up to date. If bringing it up to date does not help,
then you could try uninstalling Office completely, and re-installing a fresh
copy, then bringing that up to date with Service Packs and patches.

On my desktop PC with XP Pro and Office 2003, the Microsoft Update checking
process takes about 45 seconds, on my laptop with the same, it takes about 1
min 15 secs. So your 6 minutes suggests something specifically wrong in
your system.

Another suggested area to be investigated is the file
C:\WINDOWS\SoftwareDistribution\DataStore\DataStor e.edb

Experts only: you might wish to investigate the use of the "esentutl"
command on this database file - it is self-documenting. Make sure the
"wuauserv" service is stopped first.

The final thing to try is just wiping out the entire
C:\WINDOWS\SoftwareDistribution\ folder hierarchy (by stopping wuauserv and
BITS and then renaming SoftwareDistribution). This hierarchy will be
rebuilt by the next use of Microsoft Update, but you will lose forever all
update history.

It’s important to note that with the MSI fix and the new client installed,
the CPU may still go near 100%, but the system should still be responsive
and not lock up. If another task requires CPU cycles they will be shared,
but if the system is idle, MSI will use the full cycles available. If a
task is running at the same time as MSI, the system may be slightly slower,
but should still be responsive during this time. Key to remember the MSI
fix and the new client address unresponsive or locked systems. CPU spikes
during some scans are expected, machine unresponsiveness is not. If your
watching the process monitor, you will still see 100% CPU during some scans
and this is expected behavior.

Yes, it *can* take 6 minutes or more when scanning for updates, especially
with Microsoft Update as the default.

Workaround: Change the default from Microsoft Update to Windows Update: Go
to Microsoft Update > Click on Change Settings in left pane > Scroll to
bottom of page > To Stop Using Microsoft Update > Disable Microsoft Update
software and let me use Windows Update only (check). cf.
http://support.microsoft.com/kb/901037

With Windows Update as your default, you will need to check in at Office
Update to keep your Office applications fully patched:
