OT: What Info Does Your Computer Whore Out?

I was wondering what information apart from my ISP info and IP address is my whore of a computer broadcasting to each and every web site I might visit? Does it give them my PC name, network name, or other what we all would consider to be private info?

And what can I do to stop my whore of a machine from giving out any information other than IP and ISP info?

However, a browser can find out a lot more. Some versions of IE allow sites to check for the existence of files, for example.
