I just finished formatting my computer. installed xp pro,
and when I entered windows update site, for some reason
it said:
"There are no updates available for your computer. Please
check back later." - which can't be correct, cause i
havent done any update!! and i know there are lots of
update such as SP1 and more security stuff!! what can I
dO? OHH AND theres no Installation History!

*i used one of the keys in the xp key changer, cause i wanted to be able to install SP1 from the windows update site without having to change the key.

PLEASE, if someone knows.. i need help with this.. i feel very much not updated :) LOL...

u shouldnt get no worries, if you didnt get the devils0wn winxppro serial number.
check the for the system properties > product id -- to be sure that u r eligible to install sp1. check for those blacklisted product id combos.
once again, if u used a bluelisted 'legit' key u shouldnt get no worries.
go to start > programs > windows update. it will ask you to install something about twice. do it until u get the windows update page :)
