All the icons have disappeared from my desktop

Please, follow the instruction below:

1. Right-click anywhere on the desktop. Since there are no icons on the desktop, it should not matter where you right-click.
2. Click on "View" in the pop-up menu.
3. In the pop-out menu, look to see if there is a checkmark next to the "Show desktop icons" setting. If this is missing, this is exactly why you suddenly cannot see your desktop icons. The good news is nothing is lost, you just need to re-enable the setting.
4. Click "Show desktop icons" if the checkmark is missing which will toggle all of the icons back onto your desktop.

I’m glad I was able to get that sorted out for you.
