I am following your website for wonderful tutorials. This is the first time I am posting a comment. I am using Sony Vaio which came with Win 7 basic. As a MSDN member, I installed genuine Win 7 pro. My question is, how do you get that vaio icon while clicking my computer properties. I am not able to do so. Can you post a tutorial on this, or email me if possible. Thank you.
