basicly its microsofts way of getting there money
unless you bought the copy of windows yourself or got it straigh from a dell or a big company
there is a chance that you running a pirated version of windows
sometime when you buy a computer off ebay or from a garage sale or a small place that assembles computers thell try to save money by using one copy of windows xp for x amount of computers and basicly the owners wouldn't have a clue that there copy of windows wasn't authentic
so microshaft came out with advantege crap basicly the point is
if you have an authentic version of xp it shouldn't bother you
you get all your updates every things good
but if your a pirate or you bought a computer from one of those places that install one licensed copy of xp on multiple computers it wont let you update and eventully unless you some how find a way to apply the updates with out automatic update your screwed if a big threat for windows xp machines come out
