In order to completely replace explorer, and have your replacement be the default shell which opens up when you log in, create a REG_SZ value called Shell in [HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon] using the registry editor. This will completely replace explorer for your account, making it unnecessary to use any taskbar hiding/killing techniques.
