XPfree - Free Optimisation info for Windows XP, Vista, 7

XPfree is an optimisation resource for XP, Vista and Windows 7.
About me: I program, have a BSc in Comp Sci & build/troubleshoot computers on the side. So I have some idea of what I'm talking about.
I also run a music studio in New Zealand, which, as you may know, is somewhere near the penguins.
Hopefully these guides help you.

they're all $7 each, DRM-free, and they all smell just like cookies that your mom made:

This one is, like, Acoustic music and stuff. It's awesome.	This one has some aggression. It's industrial alternative. It uses CURSE WORDS just like grownups.	This one is all electronica. It's all melodic and up-in-your-face. Just like that.
