What step can Miguel take to solve his dilemma? Miguel is working on a project that requires him to switch back and forth frequently between the desktop and his open windows. However, it takes a long time to close each window individually to view the desktop every time. Use snap. Use peek. Use shake. Use pinning.

I'd go with B: Use peek

Desktop peek or Aero peek is a feature introduced in windows 7 that allows you to either take a sneak peek of fully review your desktop. When you move your mouse and click over to the extreme lower right corner of your desktop on the taskbar, you will get a clean view of your desktop window without minimizing any open applications.
