Log:
[USETUP]: Try to use correct flags for the NtCreateFile call that creates new file
directories.
DIRECTORY_ALL_ACCESS is not the correct flag, because it is used with the
NtCreateDirectoryObject API that creates virtual "directories" in the NT object
namespace; that's not our purpose here.
This commit needs review to verify which flags are actually the best.
