18. Turn off File Explorer’s Quick Access view
When you open File Explorer in Windows 10, it defaults to a new Quick Access view that shows your most frequently accessed folders and recently viewed files. If you’d rather File Explorer defaulted to the ‘This PC’ view found in Windows 8, here’s how.
Open File Explorer, then select View > Options from the Ribbon. A Folder Options window will open. Click the ‘Open File Explorer’ drop-down menu at top, then select the ‘This PC’ option. Click OK and you’re done.
