AutoPatcher XP. Anybody else out there try this? So far, so good. I thinks I likes it. I found it on Stainless Computing.com. Since then, I haven't been able to pull up the site. :/
It bills itself as an all-in-one "patch" to be ran after a clean format. No internet required. Most notably it has SP1 and a bunch of other security patches. It also has a "tweaks" section that have proved very useful. I've used a lot of different "tweaks" software. All seem to be 'buggy'. This one's been working pretty well. http://www.autopatcher.com/
