WindowBlinds is a program that that enables Windows users to completely change the look and feel of the Windows user interface. It does so by natively extending the user interface features of Windows to support enhanced visual styles.
If you have Windows XP, you're already half-way there. Windows XP includes a basic visual style engine that WindowBlinds is able to extend and accelerate to provide more features, optimize its memory usage, and improve its performance.
If you have Windows 98, ME, or 2000, WindowBlinds delivers full visual style capability to those OSes.
