Cleanup
[DefaultInstall]
Cleanup=1

Function
This parameter located in an install section is useful for when you want to delete your INF when you uninstall, but you need your INF to finished uninstalling.

In the case where you need a reboot to finish deleting or unregistering a file because it is in use, then your INF may still be needed to do this. This function causes your INF to automatically be deleted when it has finished the uninstall.

источник вроде из win Setup API. А в переведнной статье нет такого упоминания использования Cleanup. Правда API вроде года 99...

вот кстати еще содержимое setupapi.h
....
#define DIRID_USERPROFILE 53
#define DIRID_LOADER 54

#define DIRID_DEFAULT DIRID_SYSTEM

//
// First user-definable dirid. See SetupSetDirectoryId().
//
#define DIRID_USER 0x8000
...
по идее это определяемый dirid ?
