Even though I now have a broadband connection, I wouldn't dream of changing the Automatic Update setting. I still review the updates before installing. Its easy to do -- just right click on the checked update and select "View details". A window will open describing the update and providing a link to any relevant Microsoft Knowledge Base (KB) article.
Read my friend, Bill Pytlovany's article and see why "new computers FAIL" and then join in helping to spread the word.
