its an update from microsoft update.if you have automatic updates enabled you should have gotten notification of the update.if not you should be able to get it from microsoft update site.just curious,why so urgent? something weird happening with your computer?cheers.
just i had a lut uv wiruses i went tu google images and tiped in windows proffesional sp3 and it looked wery nice so i downloaded it after i seed it its downloaded and it looks the same as my old windows pro wen i go to system it says microsoft windows proffesional version 2002 service pack 3 so i know i downloaded it correctly but the theme and addons are still the same u think i downloaded it correctly?
moved to correct forum as not a pc hardware issue. sp3 just has all the updates & patches since sp2 came out.
