I assumed that this would be a popular topic but I searched several times and didn't come up with anything. I apologize in advance if I just missed the answer...

I'm in the process of refurbishing some WinXP laptops and towers. I have SP3 downloaded and burned to CD that I can install standalone. But, when I connect a system to the internet, there's another huge number of files that have been released since then. I thought I'd see if anyone knew - is there any grouping of any/all of those files available that I can install offline and not have to repeatedly download the individual post-SP3 files over and over again?
