Why is the password displayed when installing Windows Service created in C? (Resolved)

I used C # To create a Windows ServiceProgramAnd a project installer is created. Then generate the executable file of the service program and install it.
When you use installutil.exe for installation, you are prompted to enter the user name and password. I entered the username and password of my administrator.
After that, even if you switch to the adminitrator user, restart and reinstall the instance, you also need to enter the user name and password. The result is still incorrect.
The following is a prompt message. Let's see why. Thank you!
