How to achieve the shortcut icon merged into the taskbar in the win7 system

The latest replacement of the computer system, I admit that I am outdated, win8 are out, I only replaced win7, XP has been used before. However, because of the problem, the computer drive was broken, and it was difficult to install the system. Finally, a win7 system was installed to the computer.
