Switching Between Programs Using Taskbar Buttons
You may often work with more than one type of program at the same time. For example, you might want to compare price figures from an Excel worksheet with a price list you’ve set up in Word. You might want to copy text from a word processing document to a presentation program, such as PowerPoint. Switching between programs enables you not only to compare data but also to share data among programs. Windows Vista enables you to quickly switch from one program to another.
If you have more than one program running, you should see a taskbar button for each program.
Click the button for the program you want to switch to (in this case, Windows Photo Gallery). That program becomes the active program.
