Friends, you can do this. Right-click the desktop, click Properties, click Desktop, and then customize the desktop. Then check the desktop icon you need and confirm.

If it still doesn't work, your computer may be poisoned. I suggest you download a 360 antivirus version 2.0, update the virus database to the latest, and then do a comprehensive scan in safe mode. If there is a virus or Trojan horse, deal with it immediately and restart the computer. I hope my answer is helpful to you.
