Hi Bill-
Over the years, a lot of SIRS have asked about Windows "services". Perhaps you can post the following blurb on the web-site to address these questions.
 
Below are three websites that address the Windows XP Services issue and which ones can be disabled. The first one is easy to use and understandable, but includes a lot of old services not in XP. The second webpage is very reputable and addresses just XP. The third website (click on View Here on the page, you may need to register) is good but geeky.
