Stardock SkinStudio is a program that allows users to create visual styles for Windows XP and Windows Vista. These visual styles are applied by the popular GUI skinning program, WindowBlinds. A fully complete visual style will change the title bars, borders, push buttons, scrollbars, Start bar, Start menu, and virtually every other part of the Windows GUI.
The new version is designed to make it much easier for new users to get into skinning. Skinners can change as much or little of the GUI as they choose and SkinStudio will fill in the rest for them.
SkinStudio (the non-Pro version) is a free download for Windows XP and Vista.
