If your desktop shows no icons at all, right-click (or press and hold) the desktop and select View. If Show desktop icons has no checkmark, click it to add one.
If that doesn't work, try this:
Select Start > Settings > Personalization > Themes > Desktop icon settings.
Make sure the check box for Recycle Bin is checked, then select OK. You should see the icon displayed on your desktop.
Note: If you are in tablet mode, desktop icons are not displayed. To see your desktop icons in tablet mode, go to Start > Settings > System > Tablet Mode. Hide app icons on the taskbar in tablet mode and Automatically hide the taskbar in tablet mode should be turned off.
