Hi same problem here. After rotating some photo's they get a new date. Not in windows explorer but in Bulk Rename.
Above Geovane suggested to go to options, extract.... but where can i find options?.... AH i found it. It is:
Renaming options:
ID3/Exif data...
extract exif data(photos)
Now in the file window right click on de date column and select Taken(Original)
Works great now.
