CPU near 100% since running new Windows Updates

System = Toshiba Portege Tablet XP 2005

Not sure if anyone have had this problem, but my Tablet XP 2005 (SP2) have
had problems due to Windows Update. When the computer boots up, and logs
in, in about 1 minute it starts to be non-responsive due to 98-100% CPU
utilization. I actually rebuilt the machine cleanly but the CPU started
becoming unresponsive again. I traced it to the Windows Update EXE file.
You will actually see the SVCHOST.EXE which is a key file for Windows
systems but there are mnay threads hanging or running off of it, and windows
Update EXE file was one that was causing the over utilization. Soon as I
disabled update or used MANUAL in SERVICES (instead of automatic) and and
disabled Windows Update, then my Tablet was smooth and quick again.

Good Luck

What is your choice for the Automatic Updates in Control Panel? There are
choices to Automatic, Download Updates or Notify Me . . . in addition to
turning off the updates. Do you have any error messages in Event Viewer
(Application and System) showing for when the machine is first starting?
Svchost.exe is a generic host process name for service which run from
dynamic-link libraries (a description is here:
http://support.microsoft.com/kb/314056/en-us ) and there are many instances
of it running in Windows XP. Do you have the same behavior if you're using
Microsoft Update instead of Windows Update?

I got the same problem with more than one computers, different brands
and models (one is desktop, one is a laptop, and the third is my tablet
pc).

Doing a quick and dirty trace with Process Explorer from Sysinternals,
I traced it to a

ntdll.dll!RltAllocateHeap+0x18c call that takes 100% of the CPU time.

I'd appreciate a response from Microsoft about this; it started
happening right after the last round of updates (june patch tuesday).

Any help from Microsoft would be greatly appreciated.

I found this after the recent updates also and have traced it using Process
Explorer. One of the SVCHOST.EXE thread was running WUPDATE.EXE which
spiked to 98-100%


This has been confirmed already - why isn't Microsoft testing these patches
properly - numerous problems with pathces in the last few releases.

I now run it manually, I do not let it run automatically - disabled
notification and the service in control panel as manual. You are correct in
stating that there are numerous SVCHOST.EXE. This is normal as many
services are tied to this. I have identified the culprit using Process
Explorer from Sysinternal. See the other responses in
microsoft.public.windowsupdate. It has been confirmed by other people to my
post.

Too many bad patches in last few releaes of Microsoft Updates - how many
more bad patches will we be getting?

I have this exact same issue and it is driving me mad. For me it is also the
ntdll.dll!RltAllocateHeap+0x18c call that is causing the 100% CPU usage.

It seems to stem from Automatic Updates though, as once I disabled the
Automatic Updates service in services.msc, and restarted my computer, presto.
The problem has gone away entirely where as before it happened on every boot.

I'm using Windows XP Home, SP2, with all the latest patches.
