Super Task bar
Although the taskbar is still called the taskbar in Windows 7, it is called the Super taskbar because of its new look and stunning features.
Improved taskbar preview
Windows 7, like Vista, prompts running programs, but unlike Vista, clicking on the program icon in the Windows 7 taskbar allows you to easily preview the contents of each window and switch windows.
Aero Peek
This is a new feature of Windows 7, and Aero Peek makes the selected window appear as normal, while other windows become transparent, leaving only a translucent border.
Show Desktop feature
In Windows 7, the Show Desktop icon is moved to the far right of the taskbar and is easier to operate. When the mouse hovers over the icon, all open windows will be transparent, similar to the Aero Peek feature, so you can quickly browse the desktop. Clicking on the icon will switch to the desktop.
