enables users to customize the look and feel of the graphical user interface of Microsoft Windows. By applying "skins", WindowBlinds can change title bars, borders, push buttons, scroll bars, the taskbar, the Start menu and virtually every element of the Windows environment. Thousands of different skins exist and can be created using a free program called SkinStudio.
WindowBlinds 5.5 is a major update in that it is the first program to allow users to change the look and feel of Windows Vista. Thanks to a new technology called "SmartSkinning", WindowBlinds allows skins created for Windows XP to be used to skin Windows Vista. WindowBlinds 5.5 then transforms the skin, on-the-fly, to conform to the new user interface conventions of Windows Vista to give it a distinctly Windows Vista look and feel. Users of .msstyles files on Windows XP can use SkinStudio to convert their favorite .msstyles to WindowBlinds 5.5 to run natively on Windows Vista.
