Windows 10 changed many features that people loved about previous versions. When you open File Explorer in Windows 10, it defaults to a new Quick Access. If you'd rather see the familiar This PC view (My Computer), don’t fear. We'll show you how to change the default setting.
To change your default setting, open File Explorer then go to the top ribbon and click "View." All the way to the right of the menu is an "Options" button; click it. Select the dropdown menu that appears next to "Open File Explorer to." Change it from "Quick Access" to "This PC" and click OK.
