I have an older machine on which my XP SP2 crashed; I reloaded an older version of XP with SP2 (with much help from Geeks to Go), but because it was not a recent version, there are many updates that were not included. My machine has only 512 RAM (but I will increase this), a Pentium 4 processor at 2.66 GHz. I use Norton System Works and Anti-virus 2009 (Although it frustrates me, always running background stuff that sends my CPU to 100%.)
MS is prompting me to upload SP3, but I am receiving mixed messages from friends, blogs, forums, etc.
What should I do? Upload SP3 or somehow upload many (which ones?) of the updates that I don't have on my computer?
