Is this from the MSCONFIG?  If so, you can click on the checkbox to not have it come up again.
An update probably failed to install correctly.  Follow these instructions http://support.microsoft.com/kb/949358

it is not from Msconfig.  I'll try the article later today and post the results
The following page is to do with installing Exchange but the registry keys to check will be the same. I have had similar issues before with this never ending loop of wanting to restart:

You can remove the failing update by doing the following:

Click on the Start >> run
Type %windir%\SoftwareDistribution\
Open the "DataStore" folder and delete the contents of this folder.

........and then.......
Restart the computer

I did a system restore back to 4/3.  Didn't help.  I deleted the files in the datastore.  didn't help.  

Any other advice?

I know this might me a long shot, have you uninstalled the updates you ran before the message appeared?

I don't actually know when it started, because the user never told me.  I saw it because I was working on it.  I did go back an entire month but that didn't help.  It's not critical, because the user just clicks restart later.
Try turning off the UAC on the machine and see if you still get the same problem. If it goes away then there is some issue with an unsigned application wanting to run. You may have to trawl the event logs to see what it is, or alternatively, disable everything in msconfig apart from Microsoft stuff - that includes under the services tab! Then try re-enabling them until you find the culprit

UAC is off.  I think disabling msconfig is a good place to start.  I'll post when I'm there tomorrow

Thanks.  disabling msconfig identified the problem.  It was a DVD program
