I used to be able to share my C drive(all folders except the system protected folders like Windows, Program Files etc.) in Win 7 x86 by just sharing C. After reinstalling Win 7 x64 SP1, I discovered that only folder names that begin with letters "less than" P are shared. How weird! I have to manually set individual unshared folder's shared permission to Read for Everyone. Is this a bug or do I have some abnormality in my Win 7 x64 installation?
