Windows 7 Contact way of Microsoft

I guess the only way is to make contact through common channels. But I bet, it won't be easy. If you can make it to the secretary of the assistant of the assistant's secretary etc. you can consider yourself lucky. Big bosses aren't that easy to reach. You won't even be able to reach me directly, and I'm not a very big one.
Thanks, but I don’t think that good for me, as I want to point the weakness of Windows, but I don’t want more people know that
