Windows is "protecting" various directories and that can get in the way as well.

You haven't shown what these are in detail, though. Use getfacl to see what Cygwin thinks the permissions are and icacls to get the Windows view. Once you know what the ACL look like it usually becomes clear what you need to do to get what you want. In your particular case I'd try to recursively do a 'setfacl -kb' to remove all ACL and inheritable defaults. Again, it's possible that your user has insufficient permisions to do that (which will then result in some ACL still present, i.e. a '+' sign after the permission bits in 'ls -l' output).
Keep in mind that running things as a member of the Administrator group usually confers some extra permissions on top of that, like Backup/Restore privileges.

I have a dedicated build directory outside anything that Windows cares about and mount that under /mnt/share from Cygwin. I usually remove all inheritable and default ACL on the toplevel directory before populating it.
