Wez's Evil Shell Desktop is a replacement for the default Windows XP and Windows Server 2003 graphical shell (taskbar, start menu and "tray").
The default explorer shell uses quite a lot of run-time resources and can be quite slow to use for "Power Users". This shell provides the following features but uses only a fraction of the resources that explorer.exe uses:
Quicklaunch icon bar
System Notification area (aka "Tray"), including tray bubbles
