When playing a game fullscreen I would like to be able to be able to view the taskbar by hitting the windows key without it shrinking the screen that is open. We bought two identical machines at the same, and one does this and the other does not.Also a side note the screen also minimizes when I change the speaker volume using the keyboard.These are HP 9220e's running Windows 7 One does this the other does not.

I think your issue can be mostly caused by your hardware driver, and game settings. Please let us know if your game support the Windows mode.If you want to open other task, it's better to exit the game first, or else, or your game may crush. At this point, it's better to update your drivers for your computer, especially for the display card. Then apply the same settings in the game.I wish this would help you.
