Right-click Start

Click Tools menu item
Click Folder Options
General Tab

Default is to Show common tasks in folders. This divides folder window into a task and folder pane. The task pane give access to File and Folder Tasks, Other Places, and Details.
Recommendation: Select Use Windows classic folders and get a lot of space back.
