　　win7下使用chrome，在下面的图标栏中，点击一个chrome图标，会出现另一个图标。
　　
　　解决方法：
　　I've just found an easy fix from Superuser.com. Please check the steps here : Google Chrome pinned to Windows 7 taskbar not opening under pinned icon - Super User
1. Start Google Chrome (this creates a "new" Chrome taskbar icon)
2. Right click on the "new" icon and select "Pin this program to taskbar"
3. Go to: C:\Users\YourUserName\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
4. You will see the two pinned "Google Chrome.lnk" here. Delete the "Google Chrome.lnk"
5. Make "Google Chrome (1).lnk" readonly: Right Click -> Properties -> General tab -> tick Read-only -> Click OK
　　
　　Go to: C:\Users\YourUserName\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar
Rename Google Chrome (2) to Google Chrome (1)
Done!!
