- The initial dwWin32ExitCode for a disabled service is ERROR_SERVICE_DISABLED and ERROR_SRVICE_NEVER_STARTED for non-disabled services.
- The initial dwWaitHint is 2000 (2 seconds) for (user-mode) services and 0 for drivers.

Extra fix: avoid derefencing potential null-ptr.
And also, as bonus, comment the function so that logic can be easily understood.
