According to the testbot results CreateDirectory("C:\\", NULL) fails with ERROR_ACCESS_DENIED for not administrators. However with UAC enabled and not and administrator account I get ERROR_ALREADY_EXISTS in that case with Windows 7 64-bit running on real hardware. Moreover, Wine doesn't really perform any access checks in that case and blindly assumes that returning STATUS_ACCESS_DENIED is correct behaviour for the drive's root: dlls/ntdll/directory.c,lookup_unix_name(). This patch fixes an application that can't find its data files because after it receives ERROR_ACCESS_DENIED it stops further directory traversing.
