Umm. . . I've never really had to experience upgrading SP's because I was fortunate to get a computer that already had SP2 for Windows XP.

But SP1 hasn't been released yet for Vista, and as some people already know I have Vista. So how does this work? Is the update free for SP1? Or do you have to purchase a software to use it? Or are SPs even upgradabe? Will I be forced to purchase a new Vista computer to get the new Service Pack for Vista when it comes out? I really need these questions asnwered.
