The `ServiceInstall` element's `Account` attribute specifies the account under which the service runs. The `LocalService` account is a built-in account with reduced privileges that's appropriate for most services. Common values include:

- `LocalService`: A built-in account with reduced privileges and no network credentials.
- `NetworkService`: Similar to LocalService but has network credentials.
- `LocalSystem`: The highest privilege level (use with caution).

When you build the project, the output is an MSI file that can be used to install and uninstall the service.
