WindowBlinds is a program that allows you to completely change the look and feel of Windows to however you want it to look like. It allows you to completely customize your desktop by changing the style of title bars, buttons, and toolbars. You can change the look of buttons and check boxes by assigning them skins, or personalities, and you can assign buttons that will launch programs to toolbars. You can create your own skins, choose from the four that are included in the program, or download additional ones. You can also choose to exclude certain programs from WindowBlinds if you dont want to change their appearances.
