Hi Mark,
svchost.exe is a legitimate process and there can be more than one running. Right now I have three running. svchost.exe loads services and basically, the more services running it will take more svchost.exes running to load them. That said, svchost.exe can also be a malware, a trojan, etc.
A description of Svchost.exe in Windows XP

The first thing to do is make sure that your machine is malware free.
UPDATE your antivirus software and run a full system scan.
UPDATE whatever anti-spyware applications that you have and run a full
system scan with each one.
You might want to start in Safe Mode to run your antivirus and anti-spyware
software.
Running a full system antivirus scan or anti-spyware scan in Safe Mode can
be a good idea. Some viruses and other malware like to conceal themselves
in areas Windows protects while using them. Safe mode can prevent those
applications access and therefore unprotect the viruses or other malware
allowing for easier removal.
''In safe mode, you have access to only basic files and drivers
(mouse, monitor, keyboard, mass storage, base video, default system
services), just the minimum device drivers required to start Windows.''
Because of that some malware does not load in Safe Mode and is easier to get
rid of.

Once you are sure that you're malware free and still have a 100% CPU usage problem with svchost.exe start a new thread.
Apparently
http://support.microsoft.com/kb/927891
was supposed to fix
http://support.microsoft.com/kb/916089
I have neither of those, I haven't had an update since the tenth of March.

The process that was running at 100% was svchost.exe, network service.
Sorry, I should have mentioned that when I originally posted.

Since you know that you were running at 100% CPU Usage you must have

Was there one process running at 100%?
If so, what was the process or what was the process that was using the
biggest percentage.
In the Task Manager on the Processes tab under the CPU column. Click the
CPU column header twice to sort the processes by the highest usage.
CPU Usage
[[In Task Manager, the percentage of time that a process used the CPU
since the last update. On the Task Manager Process tab, the column
heading is CPU.]]

A couple of weeks ago, when booting into Windows, I found that 100% of
my CPU was being ulitized. This could last up to 10 minutes. I don't
know what caused it to start with because I never had this problem in
the past. I found that this is related to Windows Update. I contacted
Microsoft and I downloaded patch KB927891. After I installed the patch,
I found it did not correct the problem. Can anyone help with any other
ideas to solve this issue? Thanks.
