Windows 10 changed the default folder view for the File Explorer application. The default is now "Quick Access" Most people prefer the "This PC" seen in previous Windows versions. Here's how to change the default folder view when File Explorer is opened:
Open File Explorer.
Click “View” in the menu ribbon bar.
Click “Options” (far right) to open the Folder Options dialog.
Under the “General” tab, “Open File Explorer to:", change the drop-down option to “This PC.”
