My CPU has been @ 100% for several days now. Last time this happened, there
was a large update from Microsoft that took a long time to download &
install, but this seems excessive. There were several updates downloaded on
7.14.07, and a small one a couple of days ago. Any troubleshooting help
would be GREATLY appreciated.


Download Process Explorer.
For further information about Process Explorer see here:

To ascertain which service is causing the problem select the item (svchost) producing the high CPU usage, right click, select Properties, Services. Note there are the full names and some explanation of what each service does.
You will find further information on Services here:
http://majorgeeks.com/page.php?id=12
To trace the particular Service involved you need to turn off each service in turn and then restore it noting what effect it has on CPU usage. However, you need to take care and watch what other Services are dependent on that service. When you click on the Dependencies tab allow it a little time to display the information.

The following is an 'old'hat', but you may wish to check if you have the below mentioned updates installed.
The most usual cause recently for the 100% svchost usage is a problem with the Windows Update Service which is fixed by upgrading to the
Windows Update Agent 3.0, v. 7.0.6000.374, for 32 bit machines is available here:
http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/WindowsUpdateAgent30-x86.exe
and installing the updated KB927891 hotfix, here:
http://support.microsoft.com/?kbid=927891 for a complete fix.

Good luck :)
