Step 2: On the top right, go to the "View" tab and from there press the "Options" button
Step 3: In the menu that will open, select "Change folder and search options".
Step 4 : A new window titled “Folder Options” will open. There go to the “View” tab, then navigate with the bar scrolls down the menu until you find the “Show Libraries” option located under the “Browsing Window” chapter.
Step 5: Check "Show libraries" and then press the OK button. Close all windows.

Alternatively and for those who are "looking for it" a little more, you can display the Libraries from Run with a shell command. Press the keys shortcut Win + R and type the following in the Run box that will open: shell:Libraries
