TrueTransparency is a free application to make your windows xp border skin like vista aero glass. Without installation and use low memory is some benefits of using TrueTransparency.
TrueTransparency - Aero Skin
Some themes or skins are also available. For default, there are 4 skins. It has been reached version 1.1. New features has been added such as :
- - AeroSnap effect added
- - AeroShake effect added
- - New icon by babasse
- - ‘About’ window
- - New translation : Magyar
- - Safari and Chrome added to the exclusion list
It still supports exclude manager to exclude application that don’t use TrueTransparency’s skin. Maybe it can be better if it supports blur effect. 
I don’t get it, what do you mean by the 3rd paragraph?
it means that you can decide whether an application using aero glass or not. If not using, insert that application into exclude manager list.
