Styler

Styler is a powerful program that allows you to do a lot of interesting customizations and convert your XP into a wonderful and beautiful environment,

You can start by adding a drop shadow to your windows or change Clear Type contrast, change the color of the visual style or maybe the wallpaper

But if I have to highlight a function in Styler, I choose Styler Toolbar, that function that will convert your Windows Xp toolbar and give it the look and feel of Windows Vista or Mac OSX.

Finally, when you run styler you do not notice an extensive consume of resources, in fact, it does not consume more than 1MB.
