It's a service pack. It has the updates that you get from microsoft all in one. It also gives you the option to delete MS stuff if you want to use something else. There must be something else in there too.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
