I already downloaded the network installation file of WinXP SP1 a while ago, as I was still planning to install a new HDD in my PC. Are there similar downloads of installs for all critical updates to date, so that I can install them all offline, rather than be sitting vulnerable for however many hours it would take to download and install them online? I'm doubting anyone would bother to mess with my PC during that time, but better safe than sorry at least. One great big file would be wonderful, but I'm guessing that at best, I'd have to download each install individually if they exist.
