As more of us are deploying Windows 7 in School like me you will find something annoying about the Navigation pane. There is a "Network" icon shown are there is no built in group policy to remove this. I have found a custom ADM template that will allow us to remove it. I have attached it on this post.

Hope you will find it useful!

Steps on how to add an ADM template can be found here:
