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, then select Change additional tablet settings. Under When I'm using tablet mode, make sure that Hide app icons on the taskbar and Automatically hide the taskbar are both set to Off.
