Actual Transparent Windows lets you apply a transparency effect to any window in Windows 2000 and Windows XP.
The transparency effect looks very impressive and can be highly useful with such windows as the Windows Taskbar, WinAmp, the Start menu, drop-down menus and lists, any Instant Messenger and even application windows. Some examples:


A transparent Taskbar doesn't hide any part of your desktop wallpaper!
A transparent Start menu does not obscure icons on your desktop.
Do you like changing skins on Winamp? A semi-transparent Winamp looks really stylish and impressive!
You can add different transparency rate for each Winamp window such as Winamp Main Window, Winamp Playlist Edit
