Okay this would still seem like a PHP issue as in moving or deleting files automatically. You are going to have to give me time to set up a specific testing environment and this is going to take me a while to do since I do not specifically myself run a windows site.
However just looking at your error it is telling me you have not set permissions to READ WRITE EXECUTE ON THE UPLOADS AND OR DATA DIRECTORY AND THE CHILDREN OF THOSE DIRECTORIES. If you did you would not get a unable to move statement from php.
