Launching Windows 7
Launching Multiple Instances of the Same Software in Windows 7
There are times when you might want to open multiple instances of the same software program quickly, such as when you need to work on multiple documents in Word or Excel, or when you want to launch multiple windows of your browser.
In Windows 7, you can do this easily. Just press and hold down the SHIFT key while left-clicking on the first instance of the program in the Windows taskbar, and a new instance of the same program is opened.
