Two issues in the code

[EddieIvan01]

LPWSTR lpwStream = (LPWSTR)DS_STREAM_RENAME;
fRename.FileNameLength = sizeof(lpwStream);

sizeof(lpwStream) is always 8 bytes on 64-bit OS

FILE_RENAME_INFO fRename;
RtlCopyMemory(fRename.FileName, lpwStream, sizeof(lpwStream));

The FILE_RENAME_INFO.FileName buffer need to be allocated by yourself

Hi there, this will be fixed in the next version with a few more improvements.
