Windows 7 cleverly switch between windows

Usually we switch a window to use alt+tab to select one by one, but when there are more program windows, this method will be less efficient, and it will be more difficult to locate the window you need. In Windows 7, there is a new way to switch windows faster:

The first method: hover your mouse over a running program icon in the taskbar, and the class will be displayed above the taskbar. A small preview window of all content has been opened, and then the mouse is moved to the desired preview window, and the interface state of the content is displayed on the desktop instantly, and the preview window can be clicked to quickly open the content interface.

The second method: it is close to the previous one, but you don't need to use the mouse to select and hold the Alt key, then click the left mouse button on the program icon that is already running in the taskbar, in the taskbar. A file preview window opened by this type of program will appear above the icon. Then release the Alt key and press the Tab key to switch between several file windows of the program. After you select it, press Enter.

These two methods allow you to quickly find what you need in a large number of program windows, especially if each program opens several windows.
