There is a lot of skins to make your Windows look like Windows Vista, but to achieve the "Aero Glass" effect on windows xp, there is only one thing to do: Buy WindowBlinds 5, from Stardock.
Once you get windowblinds, go here: http://vistastyles.org/
and get a cool theme, wall, icons, etc.
Then download this: http://www.joejoe.org/index.php?opti...d=12&Itemid=29
That Vista Customization Pack is a system patcher, not as powerfull or complete as Flyakite, but U should give it a try.
Hope this helps!
btw.. this is a mac emulation site, dont get "offtopic" lol.
