Im used a mixture of stuff really. The Vista Transformation Pack that was posted earlier in this thread. That installs Vista icons, sounds, tool bar, windows, start up screen, basically everything. I didn't use the icons from that pack though. I use so many icons from different sets for different file types thats its hard to say where i got them all from.
The vista transformation pack you can get
here. I set it up for Aero Style (Glass Beta) Glass Dark 2. With the transparent glass windows turned off.
The windows media player skin is called TinyMachine (CA5P3R vs Juanchis) you can get that from
here
The wallpaper was from
Pixelgirl and is called Minimalistic Black and White, direct link to the wallpaper is
here
Errm, and the windows live messenger was hacked to get rid of the advertisements and other unwanted buttons with A-Patch, which you get from
here
Hope that helps
