- Replace the UNICODE_STRING usMessage by a PWSTR pszMessage.
- Use the "%02d:%02d:%02d" time format and get rid of the safe string printf because the string will NEVER be longer than 8 characters.
- Rename the timer id constant because it is NOT a resource id.
- Rename variables according to the coding style.
- Add empty lines to separate logical blocks of code.
- Add spaces according to our coding style.
- Move g_hShutdownDialog and g_bShuttingDown into the shutdown parameters struct.
- Pass a pointer to the shutdown parameters to the shutdown thread and the shutdown dialog and use the pointer instead of the global variables.
- Move the timer code into a separate function because it requires local variables.
