Custom visual styles - The new Desktop Windows Manager in Windows Vista only allows visual styles created by Microsoft. Creative minds on sites like DeviantArt create cursors, icons, wallpapers and themes. After using VistaGlazz you can now use custom styles as well.
Transparency stays when maximized - If your video card is DirectX9 certified and Windows Aero is activated you’ll notice the new transparency look. Normally in Windows Vista, the transparency only lasts until you maximize a window. VistaGlazz ensures transparency, even when your windows are maximized.
