if i install with the sp 1 cd though i will have to back up all my files because i will lose them cuz i will need to repartition, and the sp 2 thing i got on the cd was the same as the download, but it was such a big file, and im on dial up, and it sent me a link to get the cd instead of having to download like 250mb or so.
Someone just told me as long as you dont register the cd key, it will work fine on multiple pcs.
