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.

If you like what I'm doing here and want to support the upkeep of this site,
feel free to buy one of my albums -
they're all $7 each, DRM-free, and they all smell just like cookies that your mom made:
one is, like, Acoustic music and stuff.
one has some aggression. It's industrial alternative.
It uses CURSE WORDS just like grownups.
one is all electronica. It's all melodic and up-in-your-face.
Just like that.
