By default, there are no folders pinned to the Start Menu in Windows 10. Fortunately, you can use the Settings application to display several common folders in the left-hand column of the Start Menu.
To configure the Start Menu to display a folder, first launch the Settings application. There are three ways to launch the Settings app. The first is to open the Start Menu by either clicking the Start button on the left-hand side of the Taskbar or by tapping the WINDOWS key on your keyboard. Once the Start Menu appears, type the word “Settings.” The Settings app will be the top hit, and you can launch it by clicking on its icon.
The second way to launch the Settings app is through the Action Center, Windows 10’s notification area. You can open the Action Center by clicking on the Action Center icon in the Notification area in the right-hand side of the Taskbar, by swiping from the right edge of the screen on a Windows 10 tablet, or hitting the WINDOWS+A keys simultaneously. Once the Action Center opens on the right-hand side of the screen, you can launch the Settings app by clicking on the All Settings icon.
Finally, you can open the Settings app at any time by hitting the WINDOWS+I keys simultaneously on your keyboard.
Once the Settings app launches, select the Personalization item, and then click on the Start item in the left-hand column. This will bring up configuration options for the Start Menu. At the bottom of the list will be a link labeled “Choose Which Folders Appear On Start.” Click on this link, and you will see a list of folders that can be pinned to the Start Menu. Select the folders you wish to have displayed, and the next time you go to the Start Menu they will appear on the Menu’s left-hand column.
