The specific functions and interfaces are as follows:

Right-click the menu and save it automatically when Windows loses its focus. You can choose whether to duplicate the name, move the prompt, and delete the prompt!
I hope you will give more comments. If you need to comment out the program, please leave a message. When there are many people, I will write the process and code comments into an article!
I will not post the program file code. Please download and view it directly.
