How to delete the registry in mysql

Due to installing the executable file of a certain project, I was prompted to uninstall MySQL in order to install MySQL itself. Then I disabled the MYSQL service. After deleting the folder, I found that I was still prompted to uninstall the MYSQL service. This is very confusing. Finally, it is found that the registry needs to be deleted before reinstallation can be carried out.
