Use the command method and use the command prompt to restore the icon. The following is the specific operation method:

1. Open the running program in the start menu, and then enter the cmd command and confirm.

2. Then, in the command prompt window, enter the command assoc.lnk=lnkfile and press Enter. Because the command is very concise, you can't make mistakes with symbols. You'd better copy the command directly here and paste it into the command prompt window to avoid mistakes.

3. After pressing Enter, you will be prompted. Lnk=lnkfile indicates successful repair.
