In the past I have seen that opening a temporary file on Windows did not honour any of the environment variables you mention. The result was, in fact, that a temporary file would get opened in the root directory of the disk the program was running on. This failed when that disk was a network disk, because I was not allowed to write there. It may have improved since then, but I just wanted to make sure this is not getting an issue again.
