Don't worry if you can't find the libraries in Windows Explorer. They are still there - just hidden. Here's how to make your Windows Explorer libraries reappear.
QUESTION: I recently performed a clean installation of Windows 8.1. The process seemed to go without a hitch, but I haven't got any libraries in File Explorer. How can I get them back?
HELPROOM ANSWER You'll be pleased to know that the libraries are still there, they're just hidden by default.
To make your WIndows Explorer libraries reappear, open a File Explorer window and click the View tab. Now click on the Navigation pane icon at the top left and select 'Show libraries' from the pull-down menu. Your libraries should now be visible in the Navigation pane.
