OK, Fed, now I have the same View as you; it's the Details View, with "Show in Groups" disabled. I still have the left panel, with System Tasks, Other Places, and Details; I don't know how to disable that.
Edit: jenbot's My Computer window still looks abnormal, though. Notice the 0% above drive C and 80% above drive E. Well, I finally figured out how to make My Computer window look like hers. She's using a Details View, with Icons arranged by Free Space.
